Appearance
This beetle is characterised by a somewhat coppery or greenish metallic tint. The typical form, characterised by a metallic pronotum, is widespread in Europe, except for most of Spain and the Southern Italy. In such regions, in North Africa, and in Asia to Japan, the species is represented by some subspecies characterised by a more or less red pronotum. The antennae are longer than the entire head and body length in male and as long as body in females. Nevertheless, the Oriental subspecies have usually shorter antennae.It can be found in Great Britain locally, for example at Caldicot and Wentloog Levels otherwise known as Gwent Levels SSSI

Behavior
The adults are usually found on leaves, especially those of the willow trees, where the larva of this species lives.References:
