Aegomorphus clavipes, widely distributed species, occuring in almost whole Western Palaearctic ecozone, has been described from Austria as Cerambyx clavipes by Franz von Paula Schrank in 1781 [▽]. In central Europe is the species a typical inhabitant of sub-mountain deciduous forests with larval development in broad spectrum of broadleaf trees (Fagus, Quercus, Tilia, Corylus, Juglans).

The taxonomy of European Aegomorphus genus was for years relatively simple, with two known species only - a depicted common pan-European Aegomorphus clavipes (Schrank, 1781) and rare Aegomorphus krueperi Kraatz, 1859 from Balcan peninsula (Greece, Bulgaria). A new species, Aegomorphus francottei was described by Gianfranco Sama in 1994 also from Balcan peninsula [❖]. Situation become complicated after description of the fourth species by Jacek Hilszczański and Cezary Bystrowski in 2005, Aegomorphus wojtylai, from Poland [✧]. This interesting species, very close relative to Aegomorphus clavipes, was eventually synonymized with Aegomorphus obscurior Pic, 1904, and Aegomorphus francottei was moreover reported also from Poland [✧].

Body length:7 - 17 mm
Life cycle:2 years
Adults in:May - August
Host plant:polyphagous in deciduous trees (Populus, Tilia, Betula, Alnus, Fagus, Salix etc.)
Distribution:West Palaearctic region

The depicted beetles were collected in Uľanka (Bánská Bystrica district, Banská Bystrica region, Slovakia) on July 11, 2020 and reared from larvae found in dead lime (Tilia) in Křivoklátsko Protected Landscape Area (Central Bohemia, Czechia) during winters 2014-2015 and 2020-2021.
