The UK has 57 species of resident butterflies and 2 regular migrants (the painted lady and clouded yellow). The UK Butterfly Monitoring Scheme has been surveying populatons annually since 1976 and has shown evidence of long-term declines in many species. Several, including heath and high brown fritillary, black hairstreak and Lulworth skipper, are now limited to a small number of sites and some once relatively common butterflies, such as small tortoiseshell, wall brown, small skipper, white admiral and small heath, have shown steep population declines in recent years. More extreme and unpredictable weather may have a part to play here, but loss of habitat (and foodplants) is believed to be the key factor in declining populations. Many UK conservation organisations, including Butterfly Conservation, the Wildlife Trusts and The National Trust, actively and successfully manage land for butterflies. The large blue, once extinct in Britain, has been successfully reintroduced to the south west of England in recent years. This gallery profiles the full range of British butterflies, from fritillaries and browns, to whites and blues, skippers and hairstreaks, without forgetting the spectacular purple emperor and swallowtail.
