On the final day of April I was alerted that the second item on my butterfly agenda for this year was ready to pursue. I had wanted to make further visits to Sussex Butterfly Conservation’s Fritillaries for the Future Project site at Rewell Wood (SU979074) to see how things were progressing, and large numbers of the insects had now emerged for the 2019 season. On my previous visit a year ago (see here) the land management of progressive coppicing had been explained by the project officer Neil Hulme, and it was fascinating to learn about.
My second aim was to obtain more pictures of Pearl-bordered Fritillary. Though I have near perfect images in my collection already, they were all of a cold wrangled specimen at Bentley Wood in 2015 so it would be good to gain some more natural studies. After the two warm, sunny days that had triggered the mass hatching Wednesday (1st) was more subdued. And so I reasoned the conditions could be right for achieving my purpose.

Pearl-bordered Fritillary
These butterflies are hyperactive and fast flying in the sunniest conditions, so are not prone to settle and hence very difficult to capture pictorially. I arrived at the managed east-west ride early in the afternoon to find things lightly overcast as anticipated. But my BBC weather app, in so far as it can be trusted was predicting some sunshine later in the afternoon. Several people were searching along the ride and Pearls were being found.
I myself saw two fly pasts but conditions became cooler and all the butterflies went to roost. The number of people built up, since pictures had been published online in the previous two days when a record tally of 243 had been counted. Rewell Wood has now clearly taken over from Bentley Wood, Hants as THE place to see PBF. But on this day other observers were no more successful than myself and most gave up and left. At 4pm hazy sunshine did break out for a while, but the Pearls must all have gone to sleep by then since none re-appeared.
I took the opportunity to reconnoitre the length of the ride and appreciate the impressive nature of the rotational coppicing that has been undertaken here over the last few years (pictured below), all by BC volunteers. This of course replicates how such woodlands were harvested in centuries past, and it was the decline of the practice that caused Pearl and Small Pearl-bordered Fritillaries to struggle for survival themselves, with falls in number of more than 70% across their British range since the 1970s.
Weather over the next two days was not butterfly friendly, then Saturday (4th) was forecast to be sunny but with cold northerly winds. Plan A having failed I now set out to get pictures of the Pearls as the day warmed up, that being one of the more likely scenarios for success. This time I arrived at the ride’s western end at 9:45am but though the sun was out there was nothing on the wing yet. I had expected it to be quite crowded here, being a weekend but could see just one other person walking up ahead.
Things remained quite cool and big, threatening clouds were crossing the sun, though the strong wind kept the grey stuff moving. I engaged with the other observer, Adrian from Clacton in Essex and we carried on searching together. He was in just his second year of butterflying and looking for his first PBFs. Eventually we had brief views of maybe five Pearls during one sunny interval. My first three field priorities with any wildlife – namely see it, see it well, get any kind of picture – were all now gained.
By 11am the day indeed began to warm up and there were six of us now present. This proved to be a mannerly gathering since we all kept to a well trodden path at the edge of the coppiced habitat without walking in to its lush ground cover of wild plants. But inevitably we got in each others’ way at times. Once the blue areas of sky became wider and more prolonged warmth was on offer, we began to come across Pearl-bordered Fritillary (pictured below) basking open-winged on or near the ground.
The warmth from sunshine had needed to last a little while before the butterflies showed themselves, which explained their low profile three days earlier. Plan B was now working perfectly as the attractive little Pearls warmed up with the day. Over the next hour there were one after another such encounters, possibly of the same several insects. No doubt there were many more to be found had we steamed into the habitat but we remained respectfully on the margins and let our quests come to us, which is the most effective and eco-friendly policy.
My day’s results though grassy were indeed an improvement on last year’s upper side studies, and more natural than those previous premium treatments from Bentley Wood as desired. In time the Pearls became flightier and harder to capture again and one by one my companions went on their way. At 12:20 pm Adrian was the last to leave and I then enjoyed the wholly unanticipated luxury of having this place all to myself for another hour. And so field objective four, get better pictures was followed as conditions cooled a little again by five: go in with the macro lens. That produced the image at the head of this post.
Eventually my tranquillity was shattered by an interloper who asked if I was looking for Pearls then, without asking how long I had been on-site or what I had seen went straight into telling me I was in the wrong place. He boasted of seeing hundreds earlier in the week at the eastern end of the ride, with lots of egg-laying females; that being a conservation area and off limits to visitors. Though what this man recalled matches Neil Hulme’s account on the Sussex BC sightings page, I objected to being engaged with in such a way as if I must be having a bad time while the accoster does things bigger and better. I told him I only needed one PBF to get good pictures of, at which he said he didn’t have much time and that I was wasting my own. Perhaps he was a BC officer or volunteer going to do the daily count, who knows? But my morning had been perfectly fine, thank you and I opted to stay where I was, away from all the noise.
A few more PBF encounters were then enjoyed before I too headed home. This had been a largely satisfying exercise and my knowledge and experience of this species had grown meaningfully. In a couple of weeks these butterflies’ flight period will be over. The evidence of this visit was that the entire ride is being colonised as intended, as year upon year butterflies emerge from one coppiced area then move into and lay eggs in neighbouring compartments. And long may that continue.
