Aromia moschata is undoubtedly one of the most beautiful European longhorn beetles, in addition, it is very variable in color, which can be green, less often blue, blue-violet to black-violet, or copper-red. A. moschata is a Palaearctic species widespread from North Africa to Japan with several subspecies of uncertain systematic value. The nominal subspecies, Aromia moschata moschata, is focused in the Central Europe, reaching westward the Cantabrian Mts., eastwards to the European part of Russia, southwards to central Italy and the Balkans, and northwards over most of Scandinavia and Great Britain [❖].

It is a species typical of willow riparian vegetation and floodplain pastures, forests with a high proportion of Salix caprea. Development preferably in old willows, in the past mostly occurred on trees, where branches were often pruned (Aromia prefers trees weakened after technical damage, such as pruning branches, repeated infestation, etc.). The larvae develop under the bark and in healthy or seemingly healthy wood of thicker tree trunks and weak branches from a thickness of 2 cm (in this case especially Salix caprea). Subcortical corridors extend into the surface layer of the sapwood. Perennial development, probably three years. Adults occur from the late May to September, most often in July and August (depending on the local climate and altitude) [▽].

Body length:13 - 35 mm
Life cycle:3 and more years
Adults in:May - September
Host plant:primarily in willows (Salix, Salix caprea preferred in Central Europe), rarely in other decidouos trees
Distribution:Palaearctic region


Aromia moschata adults emit a pungent odor, when more numerous, a pleasant odor spreads many meters away around the infested trees and often reveals the beetles present before they are seen. The secretion, produced in glands associated with the metasternal coxae, is a mixture of several terpenes (cis-iridodial, trans-iridodial, cis-rose oxide and trans-rose oxide). It is probably a chemical defense, or an alarm pheromone, however, the function of the aggregation pheromone is not excluded either, as it is often possible to observe intense emission of pungent-smelling terpenes even in non-endangered or undisturbed individuals [✧].
