Chrysomela populi

Description:

Chrysomela populi is a species of broad-shouldered leaf beetles belonging to the family Chrysomelidae, subfamily Chrysomelinae. Length is about 10–12 mm. Head and pronotum are black, while elytra is bright red, with a black stain at the base. Some species come as orange colored.

Habitat:

It feeds on plants of the Salicaceae species, especially Populus and willow species. It is found in most Europe.

Notes:

It can be distinguished from Chrysolina grossa by its shorter antennae and less estensive pronotum - I don't think this is C Grossa because head and pronotum are not metallic blue-green colors. But because C Grossa is found in former Yugoslavia, I am not 100% sure... Photos taken @ Bikodze, Bosnia & Herzegovina.
