Aegomorphus clavipes is widely distributed species, occuring in almost whole Western Palaearctic ecozone. 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 common pan-European Aegomorphus clavipes and rare Aegomorphus krueperi from Balcan peninsula (Greece, Bulgaria). A new species, Aegomorphus francottei was described by Gianfranco Sama in 1994 also from Balcan peninsula [❖]. Situation become even 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 our 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 reared from a larva collected in a dead lime (Tilia cordata) branch in Kohoutov Mt. (Křivoklátsko UNESCO Biosphere Reserve, Central Bohemia, Czech Republic).
