A purple hairstreak (Favonius quercus) seen on the edge of the reserve and photographed by Clive Knight.
It was referred to Wiltshire Butterfly Recorder, Michael Fuller, for identification. He said:
“Definitely a rather worn Purple Hairstreak. Usually common where oaks occur but very elusive, staying round the tops of the trees and rarely flying until early evening. A few occasionally come down to lower levels to feed from flowers.”
An exciting find and a new species for our lists.
