Back in May I visited this post’s location with the excellent Mariposa tour company (see here). On two brief passes through we encountered probably a single DOT that I was the only group member to get a record shot of. I at once appreciated it only takes one lucky picture in a trip report to make things look easy, whilst in my experience such studies of settled Orange Tip species have taken hours to obtain. So I decided there and then to re-visit what is cited as the best European hotspot for the species solo in autumn, a much more reliable time of year, and devote more effort to recording this butterfly adequately.
By late July wanderlust was growing in me once more. Checking flights, walk-on fares were low in September. Then I located an attractive holiday let at reasonable cost within walking distance of the site, so this quest positively beckoned. This is how I prefer to do things at present: specific targets, plenty of time based in agreeable, self-catering accommodation; and the prospect of inspiring self-finds. And this particular tripette agenda fitted that mindset aptly.
As with my previous such exercise to Los Cristianos in Tenerife (see here) there was no need for a hire car since my destination 140km (80 miles) east of Málaga was reachable by bus at €20 return fare. So as all Orange Tips are hyperactive subjects the plan was to visit site as the day warms up, then wile away the rest of my time in and around that holiday apartment resort of my choosing. As things transpired all the buses on 15th were fully booked until 16:00 and I didn’t arrive at my accommodation until late evening. But that didn’t matter since on the following morning I made an immediate connect.
In north-west Africa (Morocco, Tunisia, Algeria) DOT is fairly common in places and continuously brooded; occurring in hot, dry, rocky places where the foodplant Caper (Capparis spinosa) grows. Outlier populations, patchily distributed across the far south of Spain are all tightly linked with that locally scarce larval host. From a possibly weak first brood in February or March, DOT numbers are said to increase progressively in each subsequent brood and peak in September. Residents are supplemented by migrants through the season and counts may vary a lot from year to year.
My strategy to record the trip target as the day warms up worked perfectly. The Castell de Ferro site is steeply sloping, so observers other than qualified mountain goats must rely on a broad track that crosses it around half-way up the hillside. At one point there is a large, low retaining wall above this track and my gut feel was that Desert Orange Tip must roost in long grass at the structure’s base. I located around 20, possibly a few more specimens there on each morning from around 08:30, and by 10:00 most must have dispersed.


Some individuals warmed up on the stone wall itself (above, top), offering quite striking upper-side studies. But most kept lower profiles in the dry grass where, having the place to myself, I could pick out some nice poses in creative light. The underside studies are especially subtle, reflecting the delicately lit toning of the subjects themselves. I believe this next sequence shows one male (top right) and two females.



These butterflies are noticeably smaller than the regular Orange Tip that is a feature of any English spring, the wingspan being 28 – 38mm. Indeed alternative names for the species are “Small Orange Tip” or even “Tiny Orange Tip”. They were also less inclined to pose flat-winged like other Orange Tips I have recorded. I believe these next two pictures are females.


Desert Orange Tips (female)
Reading things up, females have more dark scaling in the orange wing-tip but are otherwise similar to the males; while both genders may show more or less grey smudging on the wings, particularly in a streak along the trailing edge of the forewing. I understand some variation occurs from brood to brood through a season. Indeed the autumn specimens I observed are a little different to the illustrations in Collins.
At one point along the wall on Wednesday a small outcrop of Lantana was attracting attention from some DOTs, offering a different type of study that are quite attractive in their way. These images too reflect how the butterflies tend not to open their wings fully when perching.


I was disappointed to find very little other wildlife interest around Castell de Ferro. I had hoped this tripette might have some herp potential but encountered just one Wall Lizard over the two days. I saw very few other butterflies and the main added interest was a population of the locally common Scarlet Speckled moth (pictured below – see here) in a dry river bed through the town. I was content just to chill for the rest of Wednesday after two days in transit, but by mid-Thursday the fine line between what works and doesn’t in solo travel (which depends on the wildlife agenda) was wavering.
Hence I was glad to head home on Friday morning, and when I reviewed my memory card on arrival much later this exercise at once fell into the “worked” category. I am pleased with the images in this post that I would not have attained in company and especially not in a tour group jostling for camera angles with other people. That is not a reflection on any tour operator or participant, just the way I am. So I handle any lonely or anxious moments, ride out the dodgy bits and mishaps, and do things solo in the Rn’S tradition. When looking back it is only the wildlife experiences that I remember and images that I savour.
The featured site being a sensitive one for a rare migrant species, I have not disclosed the exact location; but it is known to informed butterfly circles. I could see it from my apartment’s terrace, but I wondered how many holiday home owners or indeed local people might know the precious resource presented herein is there. Visitors to the location should take great care as it contains numbers of deep and sometimes unprotected circular shafts that could cause serious injury if fallen into.
Footnote: In compiling this post I am saddened to see that Matt Rowlings’ most excellent resource EuroButterflies, that I have referred to frequently in this journal, has gone offline. If any reader can let me know why in comments that would be greatly appreciated.
