Oberea oculata

Oberea oculata is a widely distributed Palaearctic beetle species. This species is commonly found in riparian stands, forest edges, road edges, and ruderal plant communities, with a particular preference for goat willow (Salix caprea) in Europe, although it can be found on various broad-leaved willows.The adult beetles are active from June to August, during which time they can be found on leaves and twigs, feeding on leaf tissue and young bark. Females lay their eggs on live twigs or thin trunks, where the larvae later create longitudinal galleries under the bark, eventually boring into the pith wood. This tunneling can cause significant damage to the host trees, evidenced by the presence of exit holes left by emerging adults. The larval development typically spans two years, although the exact duration can vary depending on local environmental conditions.
