What a wonderful sight! Our work group spotted a beautiful female Brown Hairstreak butterfly high in a hazel bush on the site yesterday (2.9.23). It fluttered continuously from leaf to leaf, round the bush and back again. Usually it settled hanging from a leaf or twig & was extremely difficult to photograph. It was around for so long the whole work group had time to rush to the spot and watch it. It is not a common butterfly, found in only a few regions of Southern Britain, one being West Sussex, so seeing it close to the Lewes Road in Brighton felt really special.
