Euracmaeops marginatus, a species of Palearctic forest zone with a large area of occurrence from the Atlantic to the Pacific coast, belongs among the rarely collected and observed species due to the short cryptic lifespan of adults and the fact that it does not visit (in Europe) flowers. Larval development in the bark of trunks/thick branches of dead conifers. The larvae leave the trees and hide in the upper layer of the soil where they pupate at the end of the 2nd year of development. Biennial development, adults occur from mid-May to July (peak at the turn of May and June) on logs, sunlit standing trunks of dead/dying conifers and their branches. Swarming and mating take place in hot and stuffy weather, and beetles are also lured by charred standing trees [❖][✧].

Body length:♂♂ 7.0 - 10.2 mm / ♀♀ 9.0 - 11.5 mm
Life cycle:2 years
Adults in:May - July
Host plant:coniferous trees (especially Pinus, rare in Picea)
Distribution:Europe, Russia (including Siberia and Far East), Kazakhstan, Mongolia, North China, Turkey

The mounted beetles were collected in Nová Ves environs (Rychnov nad Kněžnou district, Hradec Králové region, Czechia) on June 1, 1973.

A new genus Euracmaeops gen. n. (type species: Leptura marginata Fabricius, 1781) has been proposed by Mikhail Danilevsky in 2014 [❖] for the Palaearctic species formerly included in the American genus Acmaeops LeConte, 1850 with 4 new combinations: E. marginatus (Fabricius, 1781), comb. n., Euracmaeops septentrionis (C. G.Thomson, 1866), comb. n., E. smaragdulus (Fabricius, 1793), comb. n. and E. angusticollis (Gebler, 1833), comb. n.
