Agrilus viridis

Beech splendour beetle

Description

Larvae feed subcortically in branches of a larger diameter or in thin trunks. Life cycle lasts 1 to 2 years. The larvae excavates S-shaped feeding galleries under bark of branches and trunks. Apart from freshly felled trees, this secondary pest attacks also seriously weakened, languishing trees. Sufficient food sources can cause their serious outbreak mainly after hot summers and dry years. To pupate, the larva penetrates about 5-10 cm into wood. Adults fly from May to August, when they spend time sitting on leaves of host plants. The species is broadly polyphagous on deciduous trees but preferring Salix caprea, Fagus spp. and Betula spp. The infected stems can be identified by the dark spots on the bark.
