Euracmaeops septentrionis is an Euro-Siberian species inhabiting in Central and West Europe montane and submontane coniferous forests. In the northern and north-eastern regions of Europe and Asia, it is much more abundant in lowland coniferous forests. The larva develops under and in the bark at the bottom of the trunks of dead, dying or fire-damaged trees. Life-cycle 2 years, pupation usually in the top layer of the bark, just below the surface, or shallowly in the soil. Adults active from May to August, flying around or sitting on dying or dead trees, also can be found on felled trunks, logs and occasionally visit flowers (Apiaceae). More about biology of the species in the dedicated page.
Euracmaeops septentrionis was described from Sweden as Pachyta Septentrionis by Carl Gustaf Thomson in 1866 [▽]. Currently, this taxon is classified in the genus Euracmaeops Danilevsky, 2014 and subgenus Euracmaeops Danilevsky, 2014, but this view of the higher taxonomy of the Euracmaeops/Acmaeops species cluster is not accepted by all Cerambycidologists and remains debatable [✳][✧].
Body length: 7 - 10 mm Life cycle: 2 years Adults in: May - July Host plant: coniferous trees, but the principal host is Norway spruce (Picea abies) Distribution: Romania, Poland, Norway, Austria, Russia, Slovakia, Ukraine, Switzerland, Sweden, Slovenia, Latvia, Lithuania, Estonia, Czechia (Bohemia), Bulgaria, Belarus, France, Finland, Italy, Germany
The depicted beetles were reared from larvae found in spruce (Picea abies) in Las Kabacki (Warszawa, Poland) in 2013-2016 and collected on spruce logs in Nová Huť village environs (Svor, Lusatian/Lužické Mts., Česká Lípa district, Liberec region, North Bohemia, Czechia) on June 15, 2025.Collected by our friend Adam Woźniak and Daniel Rydzi
