The taxonomic status of Euro-Anatolian Morimus species is unclear, but the recent [✧] and by presented data very well supported work of Emanuaela Solano et al. says:

"The genetic variability among Euro-Anatolian Morimus populations and the geographical structure suggest that they can not be ascribed to the currently accepted five W Palaearctic Morimus species and may actually represent a single, genetically and morphologically variable biological species (M. asper), highlighting the necessity of an extended taxonomical revision."

The existence of only one, very variable M. asper taxon, is supported also by authors of this site. But until well done revision of the Morimus genus, the traditional division to several taxa will be preserved here.

Body length:	15 - 38 mm
Life cycle:	several years
Adults in:	March - October
Host plant:	polyphagous in deciduous and coniferous trees
Distribution:	SW, S and SE Europe

The depicted beetle was collected on a dying poplar (Populus) near Thermopylae (NE Greece).
