Compton Down 20th May
We were toying with the idea of visiting the Isle of Wight specifically to see the Glanville Fritillaries, but as we were due to house/dogs/cats/kids sit for our son, in Sussex for a week, we would be unable to fit in a visit to the Isle. But I remembered that Compton had received an unofficial release of Glanvilles several years ago, so why not go there. We used to enjoy seeing them at Wrecclesham before it was ruined, so why not enjoy them at Compton...if they were 'out'. We could also combine the visit with a look for Marsh Fritillaries, but i'd not seen any online confirmation that Marsh Frits. had emerged at Compton either, but we decided we'd take a look.
We parked in the National Trust carpark under Compton Abbas airfield at the top of the down. There were already a few cars parked up but perhaps they were dog walkers? Setting off down the main track brought back memories of ten years ago, the last time we'd been here, and as we rounded a corner we suddenly caught sight of the down.
We hurried on down but made time to take a look in the quarry, which meant crawling under a barbed wire fence that I'm sure wasn't there ten years ago?
Taking a look round we found just two Dingy Skippers..
We carried on down the track until we reached the steps which led us up to the stile an onto the down. There we found two paths, one going up and one along, we took the latter as it would probably be easier going in the hot, bright, conditions. There were plenty of Small Heaths as we walked along the path which ran parallel to the track, but was separated from it by a large impenetrable hedgerow. We also began picking up Dingy and Grizzled Skippers, but we ignored these as trying to get shots would sap our energy, which we might need later if we found our targets. We followed the path for about fifteen minutes and had got to a point where the down curves round at ninety degrees. Just then I spotted a smallish ginger couloured butterfly which could only be one thing, our first Marsh Fritillary for quite a few years, so they had emerged.

As we searched around this area we began seeing more Marsh Frits. the problem was that as it was so hot in this sheltered micro-climate at the bottom of the down, they were closing their wings when they settled. It took some persistence and luck to catch an open-winged shot, the best time was as they had just landed, you had about fifteen second or so to get the shot.




We probably saw about fifteen in total, so their emergence was probably just beginning. After spending an enjoyable hour or so with these lovely butterflies we dragged ourselves away to go and see if any Glanville Fritillaries had yet emerged. As we took the path back along the down we found an amazing amount of Dingies, Grizzlies and now Small Blues, they were everywhere and really active in the heat. Heading Back down the main track not really knowing where to look, we kept our eyes on the bank to the side of the path as we walked. Having gone a little way along the path I spotted a medium sized ginger-coloured butterfly sat up on a plant stem, and thinking it was a Marsh Frit I took a closer look, but it wasn't a Marshie it was a Glanville Frit, mission accomplished.
Walking along the grassy bank it wasn't long before we found another and then three or four more..
We saw a total of 4 or five and later talked to a chap who told us that there was only one seen the day before. There was plenty of Ribwort Plantain growing on the bank which is probably why they are self sustaining. The amount of Small Blues on the bank was amazing,(but we left them for another time) they must be having a good year and the bonus was to find two Adonis Blues which looked really fresh.
