Aegomorphus

Aegomorphus

*Aegomorphus* Haldeman, 1847 comprises small to medium longhorn beetles (8–20 mm) with a robust, cylindrical body clothed in mottled grey-brown pubescence that renders them nearly invisible against bark. The genus counts five Palaearctic species, two of which occur in Europe. Adults are active from May to August and are associated chiefly with dead or dying wood of broadleaved trees, particularly *Fagus* and *Tilia*, as well as *Quercus*, *Betula*, and *Populus*. Larvae develop in subcortical galleries of standing snags, uprooted trees, and logging debris, typically over one to two years before pupating in shallow chambers just beneath the surface of the sapwood.
