A very nice and broadly distributed taxon (Europe, Caucasus, Transcaucasia). However, in Central Europe it is becoming rare due to the destruction of its natural habitats. It develops in the dead, dry wood of deciduous trees (Carpinus, Quercus, Castanea, Fagus, Ulmus, Acer). In our climate it prefers hornbeam (Carpinus betulus).

Body length:	10 - 22 mm
Life cycle:	at least 2 years
Adults in:	June - July
Host plant:	polyphagous in deciduous trees
Distribution:	Europe except North, Caucasus, Transcaucasia

The depicted beetles were reared from larvae found in dead hornbeam (Carpinus betulus) in Kančí obora (Břeclav environs, South Moravia, Czechia) in June 2017.
