Acanthocinus aedilis, a widely distributed Euro-Asian cerambycid species, is a typical inhabitant of continuous pine forests as well as small pine grooves. Development mainly under thick, rarely under the thin bark of felled, uprooted or otherwise dead trees. Because the thicker trunks are taken from the forest, the development is most often under the bark of the stumps. For standing trees, almost only the lower parts are attacked, but lying trunks along their entire length except parts with very thin bark. The larvae feed beneath the bark, creating a flat galleries. Prior the pupation, larvae bore pupal cells in sapwood, usually up to 2 cm below the wood surface. Often, in the case of thick bark, the pupal cell surrounded by oval chamber from wooden splinters is made directly in the bark or between bark and sapwood. Adults hatch from August to October and overwinter in pupal cells. Very exceptionally, after the long warm season, adults emerge wood during the autumn months. From these findings a frequently published mistake of two generations a year emerged. The life-cycle is usually two years, but the one-year one is also reliably proven. Adults occur in nature sometimes in March, usually from mid-April to mid-May, sometimes until early June. A. aedilis is an crepuscular and nocturnal species, during the day the beetles are usually hidden in the bark crevices and under the wood, but they often run over the logs or fallen trees, sometimes even fly [❖].
Palearctic taxa of the Acanthocinus genus were divided into two subgenera, Acanthocinus s.s. and Acanthobatesianus, on the basis of morphological differences at the generic level by Henrik Wallin et al. [✧].
Body length: 12 - 20 mm Life cycle: 1 - 2 years Adults in: March - September Host plant: pines (Pinus), rarely in other coniferous trees Distribution: Albania, Austria, Belarus, Belgium, Bulgaria, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, Netherlands, Norway, Poland, Portugal, Romania, Russia, Serbia, Sicily, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom, China, Mongolia, North Korea
The live beetles were collected in: (DR) - Oleško village environs (Litoměčice district, Ústí na Labem region, North Bohemia, Czechia on May 11, 2015; (ML) - Olešná u Rakovníka environs (Rakovník district, Central Bohemia, Czechia) in April 2022. The mounted specimens were collected in Kulmbach environs (Upper Franconia, Bavaria, Germany) in spring 1977.
