Europe's butterflies, beetles and dragonflies under threat

The Duke of Burgundy butterfly ( Hamearis lucina ) is among the endangered species. It is the sole representative of a subfamily known as the "metalmarks", some of whose members, especially in south America, have a metallic appearance. The Duke of Burgundy is found mainly in central southern England, although scattered colonies are found in Cumbria and Yorkshire. It is not found in Wales, Scotland or Ireland. Photograph: Peter Eeles/National Trust Photograph: Peter Eeles/guardian.co.uk The Duke of Burgundy was, in the past, primarily known as a woodland butterfly, feeding on primroses growing in dappled sunlight. There were many colonies in chalk and limestone grassland. However, the cessation of coppicing in woodlands has had a marked effect on this species, with many woodland colonies dying out as a result.

Now it is endangered throughout Europe, according to an assessment by the International Union for Conservation of Nature (IUCN).

After the last UK colony – on Dartmoor – became extinct in 1979, the species was brought back from the dead using stock from Sweden.

In Britain, it is never found more than five miles from the south coast. It is found in central Europe and North Africa, where its population is considered stable. But numbers have declined in northern Europe.

Its Latin name commemorates Thomas Vernon Wollaston , an entomologist who discovered several insect species on Madeira.

It is suffering because quarrying activities are reducing its habitat.

The island species is notable for the large black rectangle on the underside of its forewing. Photograph: IUCN Photograph: guardian.co.uk The violet copper butterfly ( Lycaena helle ) is found from the Pyrenees to northern Norway and from Belgium to central Asia. But in many of these areas, its wetland habitat is increasingly under threat. Photograph: Chris van Swaay/IUCN Photograph: Chris van Swaay/guardian.co.uk The violet copper ( Lycaena helle ) feeds on common bistort – an herbaceous flowering plant – and on white buttercup. Because of this, it is seen only during the blooming season of mid-May to mid-July.

Photograph: Jean Pierre Boudot/IUCN Photograph: Jean Pierre Boudot/guardian.co.uk The large red damselfly ( Pyrrhosoma nymphula ) lives in Britain and has a preference for small acidic pools. The only other red damselfly in the UK is the small red ( Ceriagrion tenellum ). Photograph: Jean-Pierre Boudot/IUCN Photograph: Jean-Pierre Boudot/guardian.co.uk The rosalia longicorn beetle ( Rosalia alpina ) has very distinctive markings and the male's antennae can be twice as long as its body. It is found from the Alps to Slovakia but its numbers have steeply declined.
