Habitat and ecology
The beetle be found in every place where the willow grows. They hibernate under barks or debris, and can be found under logs and mud. The species live for 8–9 months. They are active during spring, particularly in May, and can be found on the ground where the tree have started throwing its buds. From May to June the species can be visibly seen on poplars and willows, whose leaves they feed on, by the round holes left as a result. Starting from June to August the beetles start mating. The females lay their eggs on the recently fed-on leaves of plants. The eggs' colour is yellow, and are spindle-like. The larva hatches in summer, with the size of  in length, black coloured, and in resemblance of a slug. The larva feeds on the same plants that their previous generation used to feed on. The larva becomes adult within approximately three months, and the cycle continues from that point.
