Phratora vitellinae (Linnaeus) - (brassy willow beetle)

This beetle attacks willows in Europe and temperate parts of Asia. It has been also reported from North America. Poplars and birch may be also attacked. Both adults and larvae feed on the leaves and may cause defoliation. Younger leaves are preferred. Outbreaks on willow and poplars in which beetles aggregate can cause serious damage, especially on young trees. The life cycle and damage is, for example described by Urban (2006).
