Southern Emerald: an unexpected extra English damselfly – 19th & 22nd July

Since 22nd June a newly revealed colony of Southern Emerald has been reported in the British Dragonfly Society (BDS) online sightings log. This is in Buckinghamshire close to the M40 motorway. I first heard about it a week ago when Adam told me he had obtained precise location details and invited me to go with him to check things out at the site. On Thursday (19th) his work commitments allowed us to do that.

Two years ago I wrote in this journal of finding my last regularly occurring English damselfly, Scarce Emerald at a site on the Thames estuary in Essex (see here). Then a year later I observed many more of that very localised species at Canvey Island in the same county (see here). Southern Emerald is much rarer in the British Isles, with (as I understand) just two established populations in Kent and the Isle of Wight and small numbers seen occasionally elsewhere. So the emergence of this new colony is attracting much interest amongst odonata enthusiasts.

Southern Emerald (note the cream and brown two tone pterostigma)

We followed a public right of way towards a woodland where Adam had been advised to start looking for these insects, and once there it wasn’t long before he spotted a first damselfly in the trackside vegetation, then another and another. Yes they were Emeralds and yes they had bi-coloured cream and brown pterostigma (wing tags), the easiest diagnostic for Southern Emerald. Mission accomplished! Then we met another Oxon naturalist making his way back, who said there were many more of them a little further along the track.

At that hotspot I took the pictures in the next two collages. One entry on the BDS sightings page quoted 50+ and another 100+, and there were certainly plenty. Southern Emerald is about the same size as Common and Scarce Emerald, and smaller than Willow Emerald (see here); these being the four of their genus that occur in the British Isles. Southern is the only one of this metallic green quartet with bicoloured pterostigma. The lower rear of the head is entirely yellow, the thorax exhibits broad, pale anti-humeral stripes; and yes males can be distinguished by their diverging inferior anal appendages. Don’t forget that last one!

It was striking at this spot how many mating pairs were on the wing (pictured below). To quote Brooks and Lewington, eggs are laid by solitary females or tandem pairs into emergent aquatic plants or the branches of waterside trees and shrubs; and there was plenty of evidence of that. The egg is the over-wintering stage and larvae emerge the following spring.

This is a widely distributed species throughout central and southern Europe, except in Alpine regions. It is more common in the southern part of it’s range, but has been expanding north since the late 1980s. My own first record was in Sardinia in June of this year (see here). The discovery of a new colony so close to Oxford begs the question of how many more might be out there nationally, awaiting the sharp eyes of intrepid odo hunters.

The situation strikes me as another of those open secrets, that is meant to be kept quiet but which everyone with an interest knows about. The BDS requests that visitors respect limited roadside parking and public rights of way at the Bucks site, and pay due attention to personal safety. But the society is not consistent since in it’s log people are urged not to visit, then a few posts later a contributor gives away the exact location. So I have chosen not to do that, but working things out is a matter of common sense on consulting the BDS sightings page.

Three days later (22nd) I went back to this place to try to obtain less cluttered pictures. The two above were amongst my better results until the walk back, when I was able to capture Southern Emerald in the long yellowing grass by the trackside. The images below are more like what I seek in recording insects and made this return visit well worthwhile.

Far fewer insects were on the wing this time, so perhaps their emergence had peaked at around the time of our first visit and hopefully some of them might have dispersed. In the interim one contributor to the BDS sightings page had spoken of tandem pairs rising in clouds from his footfall. There were still some pairs propagating their species on this day, and I managed a few more pictorial records (below).

A few years ago a small number of Blue-eyed (or Southern Migrant) Hawker dragonflies arrived in Britain in the same area of Essex as the Scarce Emeralds referred to at the start of this post. That colony is now thriving, and as of today BEH has also been reported in 2018 from Kent, Sussex, Cambridgeshire, Hampshire, Dorset, Somerset, Gloucestershire and even as far south-west as Cornwall. I do hope this latest continental European migrant, Southern Emerald damselfly is as successful in expanding it’s own range and that before too long we might find them just up the M40 motorway in Oxfordshire.

Roseate Terns at Hill Head, Hants – 17th July

This is a bird I really should have connected with long before now, but one circumstances have always seemed to conspire against. One of only two regularly occurring migratory Terns in Europe I had not observed until now (the other being Sooty), there are good numbers of British records each year. So most seasoned birders will have it on their lists. These credentials all gave Roseate Tern “huge lifer” status.

My long standing ill luck concerning this species looked set to continue when on going away from home a week ago two adult Roseate were reported daily during my absence at a convenient location, the Solent by Titchfield Haven NNR. Mid-July is when failed breeders begin to move around, and birds were also reported from other places nationally. Then upon my return last Saturday the Hants Terns relocated to Poole Harbour though not for long.

Yesterday (16th) they were back on the Solent, resuming a routine of loafing with Common Terns and Gulls on mud and shingle by Hill Head Harbour (SU534023), then moving onto the adjacent reserve’s Meon Shore scrape at high tide. I didn’t hear about their return until mid-afternoon, and my first reaction was to go down the following morning. That thought lasted about five minutes before I upped and went, and didn’t the buzz that comes from a bijou twitchette such as this feel good.

I arrived 80 miles later at some time after 5pm to find the tide lapping against the sea wall and Titchfield Haven already closed to the public. It would be wrong to take issue with that, since the reserve is manned by volunteers and health and safety legislation no doubt rules against visitors entering out of hours, but such an early 5pm closure was still inconvenient. I checked through the Terns on the nearest lagoon, then explored further to ascertain there were indeed no viewpoints from where the scrape could be viewed from distance.

Returning to Hill Head Harbour at around 6pm I found the tide was going out again and Terns were beginning to congregate on the exposed “beach”. Two more birders joined me and for the next 90 minutes we watched the comings and goings on the falling tide, though all of the Terns present were Common. But this morning (17th) the Roseates were reported again first thing from this exact same spot and so I reverted to plan A.

The second attempt was at the opposite end of the fortune scale to the first. On re-arriving at around 11am I enquired of a departing birder, to be told the two adult Roseate Tern were out on the shingle and a few people were watching them from the sea wall. I parked (it’s free here) then hurried over, observing my usual priorities of see the bird first, get any kind of picture, then try for a better picture. Someone told me where to look and one Tern immediately stood out as being different. Then I found the second Roseate.

I had got here just in time since shortly afterwards the birds flew out into the Solent to feed. I then walked around the harbour to join more birders sitting on a breakwater and when the Terns came back I took all of the digiscoped pictures herein. One predictable outcome of this post’s return to bird matters is a reduction in image quality, but I can see what these birds are. I even learned to recognise their distinctive, high-pitched call as they came and went. When the tide came right in they flew off again towards the Meon Shore scrape.

To quote the Helm guide to confusion species, Roseate Tern is slightly smaller and more delicate than Common with shorter, narrower wings; and even longer tail streamers than Arctic Tern. The previous evening I had concentrated on looking for more black in the bill. But having now read up on other diagnostics before setting out I at once picked out the pale upper side, lack of black in the tail and very bright legs that my earlier companions had discussed. All these features show fairly well in the picture that heads up this post and the two blurry crops above. The difference from the greyer-toned Common Terns was striking.

roseate tern.1803 hill head

In this picture the Roseate Terns are the paler-toned outer birds

Currently in 2018 there are around 116 breeding pairs of Roseate Tern in the UK (per RBA), restricted mainly to Coquet Island in Northumberland with a few pairs scattered elsewhere. A much larger population occurs in Ireland. The species takes its name from a pink tinge that is visible on the breast during the breeding season. Small post-breeding numbers are seen on migration in southern and eastern English counties, and it was an absolute pleasure to finally catch up with this very attractive Tern today.

Butterflies of Mount Parnassos, Greece: 20th – 22nd June

The second part of the Naturetrek tour to southern Greece I joined last month was to a further renowned location amongst lepidopterists, Mount Parnassos above the northern shore of the Gulf of Corinth. There we spent two days exploring several high meadow and roadside sites that were known to our tour leader as holding butterflies of interest. The outcome was 10 more life-list additions including Niobe Fritillary (pictured below), Great Sooty Satyr, Purple Shot Copper and various new Blues, Graylings and Skippers.

niobe fritillary.1803 mt parnassos

Niobe Fritillary

Our base was the hillside town of Delphi, a tourist trap that serves the nearby ancient site of the Sanctuary of Apollo. After arriving on 20th we walked down to some waste ground below the streets lined with hotels, eating places and souvenir shops to see what was about. Here I managed some pictures of Scarce Swallowtail (below) that in this part of Greece can belie it’s name by being more plentiful than continental Swallowtail. In my experience this big, floppy butterfly is difficult to capture well but reasonable results if obtained can be quite pleasing.

Another common Mediterranean species that yielded above average images here was Eastern Bath White (above, right). And in the town itself we came across the only certain sighting for the trip of Southern Comma (below). The latter has sparser black markings on the top side than regular Comma and the unh marking that gives this species its name is Y rather than C shaped. The latter’s European range is from south-east France through Italy, the southern Balkans and Greece.

Three new (for me) Blues were observed at higher sites. Members of this group can often look more similar in pictures than they do in the field where jizz comes into play. Then something will just look or seem different from what has been observed more commonly before, and it is then a matter of identifying exactly what the newcomer is. I felt that when butterflying alone in les Cévennes (see here), and again here in Greece amongst very knowledgeable, Lafranchis-equipped tour colleagues.

A roadside male Amanda’s Blue (below) really stood out in this respect. Its dark outer borders to the upper forewings and pale ones to the inner lower hind-wings were both very apparent, but do not stand out so much in my pictures. But the underside is more clear-cut in ID terms having less orange than related species, and the clean looking unf with no cell spot is characteristic. The female, found at the same bramble patch as the White-letter Hairstreaks of an earlier post (see here) was less difficult to confuse. This was also a pleasing sighting since like many Blues females tend to keep a lower profile than territorial males.

Amanda’s is distributed across much of central and eastern Europe from the Baltic southwards into more mountainous Mediterranean areas. Perhaps surprisingly we found the even more widespread Idas Blue at just one meadow location. This common European Blue is similar in size and appearance to Silver-studded but with narrower forewing borders and other subtle differences. A clearer diagnostic is the array of black dots along the bottom edge. I only managed to gain images of our specimen (below) in the tour leader’s jar.

The rather more scarce Blue Argus (pictured below), another resident of the Balkans, Greece and Turkey, was located at one stony, high altitude site. There we came across a mating pair (far right), in which the Chapman’s-like white patch on the unh stood out in the female. Otherwise this butterfly rather suggested a smaller version of Chalkhill Blue. And that is the last of this complex and fascinating group for these two trip posts.

Two more regional Graylings made up their own group’s quota for the trip. Unlike some of its very similar members that have featured in this journal recently, Freyer’s Grayling (pictured below) was unmistakeable due to it’s underwing pattern. The pictures below were taken at Galixidi on the Gulf of Corinth during our relocation from Kalavrita. But we also encountered this butterfly at the Sanctuary of Apollo and on Mount Parnassos itself.

The evocative sounding Great Sooty Satyr is one of those Graylings with a rather more interesting name, like The Hermit near Kalavrita earlier in the week. We recorded this larger species (pictured below) a number of times in dry, grassy places at medium altitude such as it favours. The butterfly exhibits a degree of variation between individuals in colouration and markings, especially in females.

The last new Skipper for the trip was Orbed Red Underwing Skipper (below, left and top right) that is also known as Hungarian Skipper. That brought the total of Grizzled-type species lifers from southern Greece to four and I can now tell the difference between all of them. So someone is bound now to tell me I have mis-ID’d Persian Skipper (below, bottom right) that was also observed on Mount Parnassos a number of times.

Two more familiar brown Skippers demonstrated the silliness of their parochial English names here. Essex and Lulworth Skipper (pictured below) were both encountered on Parnassos far from their attributed homes, but both species are of course distributed widely across Europe. “Norfolk Hawker” in the dragonfly world is another example of what must be some kind of historical anachronism, and I rather wish that like Green-eyed Hawker the two butterflies referred to above might also be accorded more sensible international names. Lastly, Mallow Skipper (below, bottom left) that crops up wherever I butterfly in Europe was observed here a number of times.

On 21st we were about to head back down the mountain in overcast conditions, but still stopped at one high meadow for a quick look around. The sun then broke through and the location gradually but steadily revealed its treasures. Heath Fritillary was plentiful, the first time I have encountered it outside England. Revisiting the species’ stronghold of East Blean Wood in Kent (see here) had fallen off my agenda this year because of these travels, so I was pleased to encounter it again on Parnassos. HF has pretty much a pan-European distribution apart from the southern Iberian peninsula.

Two more common and widespread continental Fritillaries also showed themselves in the meadow being discussed. I have yet to gain an acceptable top-side picture of Queen of Spain Fritillary (below left) but Spotted Fritillary (right) is often photogenic.

This was where I succeeded in recording Greek Clouded Yellow for the trip, having seen it fly by a few times on Mount Chelmos. Males have a deep orange upper side that really stands out in the field, though differences from other Clouded Yellows in the underside (below left) are not so obvious. The head colour in the picture does give some clue to the top-side colouring. A pale helice form of regular Clouded Yellow (top right), observed several times during this tour, also gave itself up to the camera here.

Two more Coppers for the trip were added in the same meadow. Having gained good images of male Sooty Copper in les Cévennes, I was pleased to add a female (below left) to my collection here. Still more satisfying was self-finding Purple-shot Copper (right), a butterfly I have wanted to experience for some time. What a pity about that unsightly tear in one upper wing. Both these Coppers range widely across continental Europe.

A last featured sighting from this place is Southern White Admiral (below) that a number of times in my butterflying past has provided excellent value. I already possess some premium top-side pictures taken in Provence (see here) and now I was able to add good underside images to my collection for the first time.

It remains to present four more butterflies of note. At one roadside location regular Marbled White were flying as well as Balkan MW. But these were of the M g procida form that occurs in the southern Balkans and Greece. They appear very black and white by comparison either with their Balkan cousins or the browner and most widespread Melanargia galathea that is a common sight in the English high summer.

On another mountain road we searched for Niobe Fritillary that features at the head of this post. This widely distributed larger Fritillary favours roadside Valerian and so was not difficult to locate. It is similar to the as widespread High Brown Fritillary but is distinguishable by black veins on the underside hind-wing and certain other diagnostics. I only managed acceptable pictures of the top side (below).

This Oriental Meadow Brown (below, left) was observed at the same ski resort bramble patch as the female Amanda’s Blue and White-letter Hairstreaks. By comparison with regular Meadow Brown the underside top wings have a rather cleaner look while the outer edges of the hind-wings are more scalloped. The upper side if seen is very different. This species occurs in the Iberian peninsula, southern Balkans, Greece and Turkey; as well as parts of southern France and Italy.

Lastly, on the afternoon of 22nd we drove up almost to the summit of Parnassos and walked into possibly the highest meadow of the trip. Conditions were overcast on our arrival but as soon as the sun came out the rocky slope before us became alive with Clouded Apollo (above right). Europe’s four Apollo species are butterflies I very much want to experience, but having been on the wing since early May those active here were all quite worn. We had encountered even more ragged individuals twice already.

The full species count for the two part tour of Mount Chelmos and Mount Parnassos, with life-list additions in bold, is: Swallowtail <P m gorganus>, Scarce Swallowtail, Clouded Apollo, Black-veined White, Large White, Small White, (Krueper’s Small White), Eastern Bath White, Greek Clouded Yellow, Clouded Yellow, Helice Clouded Yellow, Brimstone, Cleopatra, Eastern Wood White, (Purple Hairstreak), Sloe Hairstreak, Ilex Hairstreak, White-letter Hairstreak, Small Copper, Grecian Copper, Sooty Copper,  Purple Shot Copper, Lesser Fiery Copper, Long-tailed Blue, Holly Blue, Iolas Blue, Eastern Baton Blue, Zephyr Blue, Silver-studded Blue, Idas Blue, Brown Argus, Blue Argus, Chelmos Blue, Escher’s Blue, Amanda’s Blue, Chapman’s Blue, Ripart’s Anomalous Blue, Turquoise Blue, Meleager’s Blue, Adonis Blue, Common Blue, Southern White Admiral, Red Admiral, Painted Lady, Queen of Spain Fritillary, Small Tortoiseshell, Comma, Southern Comma, (Cardinal), Silver-washed Fritillary, Dark Green Fritillary, Niobe Fritillary, Spotted Fritillary, Lesser Spotted Fritillary, Heath Fritillary, Marbled White <f procida>, Balkan Marbled White, Woodland Grayling, Delattin’s Grayling, Freyer’s Grayling, The Hermit, Great Sooty Satyr, Great Banded Grayling, Meadow Brown, Oriental Meadow Brown, Small Heath, Speckled Wood <P a aegeria>, Wall Brown, Large Wall Brown, Lattice Brown, Oberthür’s Grizzled Skipper, Olive Skipper, Orbed Red Underwing Skipper, Persian Skipper, Mallow Skipper, Dingy Skipper, Lulworth Skipper, Essex Skipper, Small Skipper, Large Skipper.

Turkish Clubtail dragonfly and some other insects in southern Greece: 17th – 22nd June

After the relative failure of my recent week in Sardinia (see here) I was glad of securing a further dragonfly life-list addition on this second June trip to Greece. Just about the only odonata-oriented location on our butterfly dominated agenda was the Strimonas valley near Kalavrita and it was there that Turkish Clubtail (pictured below) was located.

turkish clubtail.1802 kalavrita

Turkish Clubtail (male)

This dragonfly (Gomphus schneiderii) replaces the far more widespread Common Clubtail (G. vulgatissimus) in the southern Balkans, Greece and as the name suggests Turkey. Its range also extends into the Caucasus, Lebanon and Iran. The overlap of the two species in Greece is poorly understood. Turkish Clubtail is generally smaller and more slender than Common, and in mature males the eyes are much bluer, not green as the pictures in this post show clearly.

The Dijkstra and Lewington field guide states that other differences between the two species are minor, but to me these Greek specimens looked much blacker than Common Clubtails at home in England. But that could be because I have only previously observed newly emerged individuals (see here). I also wondered if the Turkish variety is less prone to taking to the tree tops immediately after emergence, never to be seen again by frustrated odo hunters, since some of those in the riverside vegetation were quite ragged (pictured below).

2018 was an above average year for Common Clubtail sightings in Oxfordshire (see here), but I myself only had time to look for them once and did not repeat my success of a year ago. Six more Clubtail species in Europe all have limited or highly localised ranges. But I have now experienced all of the three that occur more widely, having self-found Western Clubtail (below, right) in Portugal in May 2014. These (below) are both archive pictures.

The main other odonata interest along the River Strimonas in Greece was Blue Featherleg, or White-legged Damselfly as the species is known in Great Britain. I was pleased to capture images of some new colour forms here, since most of those I had come across before in England were immature or maturing males. The blue mature male form (below, left and top right) is really quite striking and just look at those splendid white legs. The immature female (bottom right) was another pleasing new find.

The default Demoiselle in the areas we visited appeared to be Beautiful Demoiselle (pictured below, top) that was abundant along both the Strimonas and Vouraikos rivers close to Kalavrita. This largest and darkest of its genus is always photogenic with entirely metallic cobalt blue wings in males and transparently greenish to dark ebony tones in females. Some Banded Demoiselle (below, bottom) were also present here. Both species are common and abundant throughout Europe.

A purely chance sample of other insects now follow that caught my attention during the week under review. I can always find space for Grasshoppers and Crickets in this journal. Greece is especially blessed with this order since the majority of its 17,000 known European members are confined either there or in the Iberian peninsula. Only around 250 species extend into central Europe while the British isles have just 30. Given those numbers I can rarely match what I find on my travels to field guides and so have no idea of what species the individuals pictured below actually are.

The top left picture is of the biggest Grasshopper I have ever encountered, while the colourful Bush Cricket was seen a number of times. I am intrigued as to whether some of these insects can alter their colouration to blend with their surroundings, having previously seen a red-toned grasshopper against red soil in Portugal (below left) and now this blue-toned individual (below right) here in Greece. The two do look superficially similar in size and shape.

Ant-lions, Ascalaphids and Lacewings are another complex order that no field guide appears to do justice to. These are soft-bodied flying insects with membranous wingspans ranging from about 3mm to more than 100mm. The large Ant-lion species pictured below left confused proceedings a number of times by resembling a dragonfly at first sight, but they are much narrower bodied and once settled pull their wings in tightly and so are then difficult to pick out from the vegetation in which they rest.

Lastly Ascalaphids provided variety on a number of times here as in Sardinia. The right hand picture is of the only one I managed to capture adequately. These fast flying relatives of the Ant-lions are generally shorter and stouter with long clubbed antennae. There are 15 European species occurring mainly in the south.

Butterflies of Mount Chelmos, Greece: 17 – 20th June

This (pictured below) is one of Europe’s rarest butterflies. Chelmos Blue flies only for a few weeks each year high on the mountain of the same name in Peloponnesian Greece. Collectors come from far and wide to steal it from the wild because though the species also occurs in Turkey and eastward into Asia they (the collectors) all covet a Chelmos from Mount Chelmos. Lying a little to the south of the Gulf of Corinth, this is one of Greece’s most well known butterfly locations in which the range of habitats can yield more than 50 species in one day.

chelmos blue.1801 mount chelmos

Chelmos Blue (male)

I now have Chelmos Blue in my butterfly picture collection, a rather more eco-friendly way of going about things, after self-finding this individual during a Naturetrek tour of two centres in southern Greece from 17th – 22nd June. As the group searched one gulley near the mountain’s summit, I walked back to the roadside after a while and noticed a different looking, fairly bright butterfly very close to our minibus. Nobody else was near and so I set about taking pictures without being sure what it was.

Chelmos Blue has a greyish underside with an arrangement of dark spots, and the broad white stripe on the lower hind-wing is a key diagnostic. On showing the above image to our tour leader on his return he confirmed I had indeed stumbled upon what was our top trip target. We then decided to stay at the spot for our picnic lunch and the butterfly appeared again so everyone got to see it in the end.

After lunch we moved on to search out Odd-spot Blue. This tiny species entails even more of a challenge since not only does it occur in Europe at just two Greek mountain top sites, but on Mount Chelmos only on a particular rocky slope, above a certain elevation where the larval food plant grows. Colonies are typically this small. Fortunately the tour leader knew exactly where to look, that after all is a pretty essential skill for a guide.

I am aware that the image cropping I employ often makes butterflies presented in this journal appear larger than life size. Odd-spot (pictured below) is a Small Blue-sized species that takes it’s name from the prominent arrangement of dark spots on the upper hind-wing. We had searched in vain a day earlier in rather too cool and damp conditions, but the second attempt was in sunshine. Having climbed all the way to the top once I opted to let others do the work this time and sat down to rest half way up.

When the sighting was called a sudden surge of adrenalin nonetheless propelled me to the higher elevation. There two males and a female had been located, this being a fast-moving insect that darts about and so tends to go out of view then appear again. The two species featured above were quite a double for our day, since no more than three of each had been found by Naturetrek groups in any previous year.

I joined this trip on the recommendation of its leader Philip Thompson, with whom I had been to the Macedonian region of northern Greece in May 2017. Noticing my interest in butterflies on that occasion he told me this June tour usually returns 80 plus species. In the event, despite untypically cool (by Greek standards) and showery conditions for the time of year, we found 86 different butterflies that for myself included a respectable 30 lifers. Happy bunny then! This tour delivered its itinerary.

The default Blue species at altitude here are Common and Silver-studded Blue (pictured below) that are both present in their thousands. In normal summer weather conditions of constant 35+ degree heat large concentrations of butterflies occur around water sources such as mud puddles, natural springs and livestock water troughs. Identification is then a matter of painstakingly picking out the specialities from the commonplace. But 2018 has been a wet summer in Greece and with much more damp ground available butterflies naturally disperse into it. In the event we still did rather well and were only actually rained off on the first day.

The other prizes high on Mount Chelmos are Pontic and Greek Marzarine Blue, but neither of these were found. It would be very unusual to record all four speciality Blues in one visit, since emergence times vary from year to year. A third new Blue for me here was Zephyr Blue (pictured below) that was present in good numbers, the easiest diagnostic being black dots along the hind-wing bottom edges. This butterfly occurs in dry habitats from Spain through Alpine regions and as far east as Iran. It is said to resemble Silver-studded Blue in appearance but is larger, and there are a number of sub-species.

Also encountered in similar numbers was Escher’s Blue (Agrodiaetus ainsae) that I had observed previously in Les Cevennes, France (see here). This largish Blue is patchily distributed across Europe south of the Alps, flying in flowery and often rocky places. But here in south-eastern Europe there is a different sub-species A e dalmaticus that appears brighter and more iridescent and that is what I saw this time. I also found my first ever female Escher’s on this trip that are encountered far less frequently than males.

The Blues are of course a highly complex group of often similar species, so I am open to correction if I have got anything wrong in this post. One lesson of this trip is that to continue to advance with butterfly identification I will eventually need a net, a lepidopterist’s jar with magnifying glass in the lid, and a copy of the out of print 2004 Lafranchis field guide. This after all is how things are done by true experts in the field, whatever some others might think about netting. Lafranchis details the exact fine diagnostics that should be matched to close inspection of every European species. Copies now change hands for large amounts of money and Naturetrek owns one that it issues to its tour leaders.

At lower elevation, in meadows and roadside habitat as we drove up to the summit, I was pleased to gain good underside pictures of Chapman’s Blue for the first time. This widespread central and southern European species is most easily distinguished by the large white patch mid-way along the array of orange sub-marginal spots. Their upper side is very similar to Common Blue, but to me the underside appears much brighter and for the Lafranchis devotee there is no cell spot. The top right hand picture is of a roosting individual on the day that was rained off, and I rather like the wet effect.

Moving on to some common larger butterflies of Mount Chelmos, one of the most plentiful encounters was with Balkan Marbled White (pictured below). I now have several European MW species in my picture collection and this south-eastern one has rather more smoky tones than the others. The often cool conditions gave rise to excellent picture opportunities of less flighty than usual and sometimes roosting individuals. Familiarity certainly didn’t breed contempt since this was one of my favourite butterflies of the trip and always good value.

Black-veined White was fairly frequent though not generally inclined to settle, as is their wont. For the first time I distinguished and captured pictorially females of this species that have a translucent quality, while some exhibited brown-toned veining by comparison with the males.

There are several Grayling species in Greece, the biggest and most often seen of which was Great Banded Grayling (below, left). Though this handsome butterfly might at first appear to resemble White Admiral in flight, upon settling the jizz and cryptic underwing patterning of the Grayling group is all too apparent. Our tour leader identified the right hand butterfly (below) as Woodland Grayling, one of three others of the genus that can only be separated reliably by close examination of the genitalia. Yes, a bits job!

On 17th, after poor weather had driven us down from the summit, I self-found another of the Graylings named simply The Hermit (pictured below) in a sunnier valley area that we headed for. This butterfly had a pale top side band like Great Banded but was smaller and when settled on stony ground the underwing pattern was totally different. I was told it was quite a scarce record for this Naturetrek tour, but like the Chelmos Blue it was relocated so all the group saw the Hermit too. That wasn’t always so easy since like all Graylings this one was a master of camouflage against both stony ground and leaf litter.

Having spent much of the first two days around the summit of Mount Chelmos, on 19th we turned our attention to some lower locations that held various species of note, closer to our base of Kalavrita. The first of those was Lattice Brown that I had seen just once previously in northern Greece in May 2017 (see here). This large and striking Brown has a long flight season from April to October, occurring locally across south-east Europe and the near East. It is known for concealing itself in dense shade so I was pleased that one individual here struck up a nicely back-lit pose before relocating to a metal gate (pictured below).

Later that morning we visited the monastery garden of Aghia Lavra that has already featured in the previous post about Hairstreaks. Amongst the mix of butterflies here were Lattice Brown again, Clouded Yellow, Southern White Admiral, Sloe and Ilex Hairstreak, Grecian and Lesser Fiery Copper, and Ripart’s Anomalous Blue; producing collectively one of the highlights of the trip. I have saved the best Ilex Hairstreak nectaring on Mint pictures (below) for this post, and things do not get much better.

That having been said, after the Ripart’s Anomalous Blue appeared it too set up as captivating poses on the monastery garden Mint. My insect pictures involve no props, no bait and with few exceptions are captured with entry level equipment in completely natural and uncontrived circumstances. What an absolute pleasure it is that butterflies and other insects allow for such an approach but then I do not regard myself as a photographer, merely a wildlife enthusiast who enjoys taking pictures as records of what I observe. To my mind that is the best sense of priorities, rather than an insect or bird being a subject for the complex technicality that is a “photograph”, and for this reason I now try to avoid using that last term altogether.

The Anomalous Blues are something of an enigma since both males and females are plain brown on the top side. Collins lists nine different European species, most of which are very tricky to separate and limited to highly localised geographical ranges. Three of these were on the wish list for this trip but Ripart’s was the only one we located. This butterfly is rather powdery in tone on the underside of both wings, has strong marginal markings, and males have a prominent white unh stripe very like the Chelmos Blue that headed this post.

The last of the “Mint specialists” was Grecian Copper (pictured above), the most frequent of the Coppers we came across through the week as well as the most vividly coloured. Our next stop after the monastery was a walk along the nearby River Strimonas where that fiery little native of the southern Balkans, Greece and Turkey was again present in good numbers. Females of this species tend to keep a low profile after pairing, so I was pleased to record one here (below, right). Another sighting of note in this location was egg laying Iolas Blue but I didn’t attempt pictures in the glary light and shade conditions, and in any case had captured the species well in Macedonia.

In the afternoon we headed higher up again, taking a very winding road above Kalavrita to a remote and scenic second home village, Souvardo. A walk onwards from there along a high track produced two more Blues for my life list and another Grayling. Meleager’s Blue (pictured below) is an attractive species with a bright blue top side and subtle, pale-toned marginal markings and dark grey spots on the underwings. It ranges fairly widely through eastern and southern Europe.

Having in the past self-found Baton and Panoptes Blues in France and Portugal, I was now pleased to record a third member of their diminutive group Eastern Baton Blue (pictured below) at this location and along a second lower track . This one is by far the most widely distributed of those three Small Blue-sized species, occurring across the eastern half of Europe from southern Finland down to Turkey then across southern Asia to China.

There are a number of very similar Grayling species in south-eastern Europe. This one (below) matches the Delattin’s Grayling illustration in Collins nicely, and I can see it is also different from the slightly smaller Southern Grayling that I observed in Corsica last autumn. Our group leader assured us Delattin’s is a good enough ID since separating it from Balkan Grayling that Lafranchis also lists (but not Collins) is another bits job.

Lastly there were the Skippers. Various Grizzled Skipper-like species were experienced during the trip but I thought of this group as too tricky to attempt to get my head around, especially as the illustrations in Collins are not of the best. Fortunately my tour colleague Paul Selby and our group leader were both very good at distinguishing them from one another. I am indebted to them both for the following IDs, and so am now getting my eye in too.

On 20th we took a walk around countryside just to the south of Kalavrita, following a track from the River Vouraikos through smallholdings and arable fields into the low hills nearby. Here butterflies of interest included Silver-washed Fritillary, Southern White Admiral and the third brood form of Small Copper. The last of those (below right) is much darker toned than the form seen at home, and some individuals can be smaller due to premature pupation.

I found Kalavrita to be a pleasant if touristy town, tucked into a verdant river valley below the slopes of Mount Chelmos in which the pace of life seemed unhurried and largely unchanged from times past. It lies at the head of a famous funicular railway dating from the late 19th century. Foreign visitors here mostly arrive by the coach load, not usually staying for more than one night so a longer remaining group such as ours was good trade for local hoteliers and restaurant owners.

After these three and a bit days described above we relocated from here to our second centre, the as notable butterfly location of Mount Parnassos across the Gulf of Corinth to the north. That second stage of this trip will be the subject of a further post in due course.
