Trypodendron domesticum

European hardwood ambrosia beetle

Description

The adult beetle is about 3–3.5 mm long. The female excavates branching galleries in wood and infects them with ambrosia fungi. Both larvae and adults feed on the fungi. Each larva excavates a short tunnel axially to the trunk in which it lives and also pupates. The larvae push a high amount of wood debris in the form of a whitish powder out of the holes in wood. It swarms in early spring and has one generation per year. This ambrosia beetle is a significant technical wood pest causing damage mainly to Fagus spp. In Europe it has two other, similar relatives. On conifers occur the strip ambrosia beetle Trypodendron lineatum and on oaks the ambrosia beetle Trypodendron signatum.
