The nominotypical subspecies, Morimus asper, has been described from Italy as Cerambyx Asper by Johann Heinrich Sulzer in 1776 [✧]. M. asper funereus, a subspecies distributed in Central-West and South-Eastern Europe, has been decribed from France as a new separate species (Morimus funereus) by Étienne Mulsant in 1862 [☆]. It is currently considered, even thanks to DNA analysis [❖], only as a subspecies of M. asper.

M. asper funereus, a polyphagous species on a plethora of deciduous trees, is occuring in deciduous forests, grazing forests with solitary trees, as well as in parks and old orchards. The development of larvae takes place in dead wood, fresh stumps, dead parts of standing trees and in wood with bark lying on the ground. Pupation in the wood, life cycle several years. Adults, occurring from spring to late autumn, live a very long time and some even overwinter successfully. M. asper funereus is a nocturnal species but can easily be found hiding in piles of cordwood or sitting on stumps even during the day. Biology of this remarkable species (sensu lato) was in detail described in a brilllant paper by Sönke Hardersen et al. published in 2017 [◊].

Body length:16 - 38 mm
Life cycle:several years
Adults in:April - October
Host plant:polyphagous in deciduous trees (Fagus, Populus, Tilia, Acer, Salix, Carpinus, Quercus, Ulmus etc.)
Distribution:Albania, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czechia, Greece, Hungary, Italy, Macedonia, Montenegro, Romania, Serbia, Slovakia, Slovenia, Turkey


The depicted living beetles were found: (DR) - Danube-Ipoly National Park (Pest county, Hungary) on May 31, 2015; (TN) - on Haláp hill (N46°55′28″ E17°27′30″, Zalahaláp village environs, Veszprém county, Hungary) on July 23, 2017; (MH) - the oak stump in Sarpdere environs (Demirköy district, Kırklareli Province, European part of Turkey) on May 31, 2011. The mounted specimens were collected in Velika (Βελίκα) beach village environs (Melivoia municipal unit, Larissa regional unit, Thessaly, Greece) on June 12, 2008.

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.
