The 5 to 7 mm large cylindrical bark beetle Colydium elongatum (family Colydiidae) is one of the species of the genus in Germany and is very similar to its sister species C. filiforme. Colydium elongatum is known to occur from the southern Part of North Europe and the British Isles over Central Europe to South Russia and the Balkan. The beetles live in deciduous and coniferous forests under the bark and in decaying wood of various deciduous trees and conifers (oak, beech, spruce, fir, and others). The nocturnal beetles prey on the larvae of various bark beetle species. Presumably the larvae are predacious too, possibly the also feed on fungi growing in the galleries of their prey. In Germany, recent records are known from most Federal States. However, Colydium elongatum is still regarded as vulnerable (RL 3). (CB)
