Big Sussex Butterfly Count

Yesterday morning I joined some of the craziest people in butterfly circles for a day long hunt for butterflies in Sussex. The event was designed to promote the start of the annual Big Butterfly Count which Sir David Attenborough, president of The Butterfly Conservation Organization, kicked off on Thursday.

Richard Bradford, Colin Knight  Martin Warren, Patrick Barkham
We were divided into two teams – my Team Purple Emperor scoured West Sussex and Team Silver-spotted Skippers searched East Sussex. We all started at the Liz Williams butterfly haven on the grounds of Dorothy Stringer School in Brighton. Following filming and photos we jumped into two Land Rovers and roared off.  The objective was to count the maximum number of butterfly species within our half of Sussex. This required good planning, knowledge of the sites visited and the butterflies we were targeting  at each location, luck with the weather and a good driver. Good video here: http://t.co/0bvmrWK5
The two teams
Team Purple Emperor had some of the country’s top butterfly people: Dr. Martin Warren (CEO of Butterfly  Conservation),  our team leader Nick Baker (nature broadcaster, author and conservation specialist),  Neil Hulme (Sussex BC Conservation adviser), Dr Dan Danahar (Environmental Science teacher at Dorothy Stringer School and Biodiversity Officer for Sussex BC), Patrick Barkham (Guardian journalist on Environmental issues and author of The Butterfly Isles) plus Richard Bradford (Headteacher at Dorothy Stringer School), Jan Knowlson (Ranger with the South Downs National Park and our wonderful driver) and myself. The weather was really kind to us. Team Silver-spotted Skippers were headed by Sussex Wildlife Trust CEO Tony Whitbread.

We got off to a great start during the traffic crawl out of Brighton when Neil cried ‘Skipper’ then jumped out and returned with our first sighting, an Essex Skipper. Our first stop was at Southwater Woods where we searched in vain for a Purple Emperor, craning our necks hoping to see one flying above the canopy of a master oak. White Admiral, Green-veined White, Comma and Ringlet soon followed. In the meadow we crossed off Marbled White, Meadow Brown and Purple Hairstreak and Large Skipper to give us 11 species. We then crossed the road to a Small Skipper site which boosted our count to 12. We then visited Botany Bay on the Surrey border hoping for Wood Whites which did not materialise. We did add a Dingy Skipper larva expertly found by Martin, plus Gatekeeper, Dark Green Fritillary, Common Blue and Red Admiral. Eagle-eyed Martin also spotted a stunning Elephant Hawk-moth resting in the grass. Our next call at Iping Common brought us an expected Silver-studded Blue then we found our rivals had exceeded our total so things got desperate. Both teams were tweeting their results and our competitive nature ensured that we got focused very quickly. At one point Team Silver-spotted Skippers tweeted a picture and claimed it was a Silver-spotted Skipper. Our eagle-eyed experts quickly declared it to be a Large Skipper and wondered what other errors our rivals had made.  What made it worse was that they had the Silver-spotted Skipper expert in their team! Much gloating at that.

On the way to Mill Hill we toured Arundel, checking buddleia bushes for a Large or Small Whites which were strangely missing from our list. Mill Hill gave us Small Heath and Small White, then we returned to Brighton. At Bevendean Down Patrick spotted a Chalkhill Blue and we then stopped at Hollingbury Park where I had seen a White-letter Hairstreak two days before.  No sooner had Neil said ‘check the thistle flowers' than Patrick exclaimed ‘there’s one’ pointing to a beautiful specimen nectaring on a thistle flower. This brought us to 22 species, one ahead of our rivals with 30 minutes to go. We returned to the Dorothy Stringer Butterfly. Haven where we bagged our final butterfly, a Peacock. The final  result was 23-21, with much jubilation on our part. Not that it was ever competitive ... Team Silver-spotted Skippers had 3 species that we were missing so the total Sussex count for the day was 26.
