Akimerus schaefferi, a conspicuous, unmistakable and rare European species of old oak forests, has been described from Tyrol as Leptura Schæfferi by Johann Nepomuk Laicharting in 1784 [▽]. The occurrence of this species is associated with the presence of very old oaks, or with coppice oak forests. It does not occur in culturally planted oak forests. A. schaefferi larvae develop deep underground in dead or dying (sometimes quite fresh) oak roots. Life cycle 3 years. Pupation in pupal cells hidden among roots in soil during spring. The adults, active from June to August, fly in warm weather around the oak crowns/treetops. They also sit on the leaves of host trees, often on the plants below them, less often on flowers (eg. Apiaceae) [❖][✧].

Body length:♂♂ 15.0 - 22.0 mm / ♀♀ 20.0 - 26.5 mm
Life cycle:3 years
Adults in:June - July
Host plant:oaks (Quercus spp.)
Distribution:Central and South Europe

The depicted beetles were collected/photographed Ladná environs (Břeclav district, South Moravia, Czechia) in June 2014 and 2016.
