Acmaeops 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.

Body length:7 - 10 mm
Life cycle:2 years
Adults in:May - July

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.
