Green Hairstreak butterfly Callophrys rubi resting on Bilberry — Clougha, April.
This butterfly always rests with closed wings, showing its distinctive, iridescent green underside — effective camouflage against the surrounding leaves of the bilberry, one of its caterpillar’s many foodplants, which include bramble, heathers and gorse. The upper side of the wings are brownish and plain apart from a small, lighter patch of scales on the forewings of the male. The eggs are laid singly in May, caterpillars are green with yellow and darker markings and brown head, and pupation occurs towards the end of July on the ground. The pupa overwinters and can emit an audible squeaking or rasping sound — apparently this attracts ants which can protect the pupa to an extent by burying it beneath the surface.

The Group is a local group of the Wildlife Trust for Lancashire, Manchester & N. Merseyside, primarily for members living in the Lancaster City Council District and immediately adjacent areas of Lancashire, South Cumbria and North Yorkshire. Meetings are open to all members of the Wildlife Trust. If you are not already a member, come along to a few meetings and, if you like what we do, join us. The Committee coordinates all the work of the Group and, in particular, arranges meetings,field outings, recording sessions, working parties on local reserves and the production of the annual Newsletter. The Recorders receive and collate records to help conserve interesting sites, to monitor changing numbers and distribution of species and to contribute to national recording schemes.
