Plagiodera versicolora (Laicharting, 1781) - (willow leaf beetle)

This leaf beetle is widely distributed across Europe, temperate parts of Asia and northern Africa. It has been introduced into North America and is an important pest of willow and poplar trees. The larvae and adults feed on the leaves and can defoliate the host tree. There are usually 2-3 generations per year and the adults of the last generation overwinter under the bark or in other shelters.

Adults and larvae are dark, mostly black. The young larvae have a cream colour, but when they grow they become darker, often with some brownish spots. They also have rows of prominent dorsal projections. The adults are 3-4 mm long, metallic and shiny with a blueish, coppery or greenish tinge.
