Agrilus biguttatus

Oak splendour beetle

Description

A metallic shiny green beetle, about 8.5-13.0 mm long. It attacks mostly older, languishing oaks in sunny and warmer locations. It is one of the major contributors responsible for oak death in Europe in the last decade. A. biguttatus lays eggs in groups into oak bark notches. Larvae bore into the bark where they excavate narrow galleries and pupate at their ends. The larva overwinters in the galleries and pupates in spring. It swarms towards the end of May and in June. Damage typically results in three dieback.

Symptom

Galleries under the bark. Larvae bore into the bark where they excavate narrow galleries and pupate at their ends. Exit hole in D-shape.
