The 3 to 5 mm large spider beetle Ptinus rufipes (family Ptinidae) is one of 16 representatives of the genus currently known to occur in Germany. The species ranges from virtually entire Europe to northern Russia and the Caucasus. The development takes place in wood of deciduous trees, e.g. oak (Quercus), beech (Fagus), hornbeam (Carpinus), linden (Tilia), elm (Ulmus) and hazel (Corylus) infested with white rot. Contrary to other representatives of the genus, the larva does not only feed on the leftovers of other insects, but on the wood itself. Like many Ptinidae, Ptinus rufipes exhibits a marked sexual dimorphism: The elytra of the female are rounded oval and covered with scales, whereas the male is elongate and without scales. In Germany, Ptinus rufipes is the most common Ptinus species and present in all Federal States. (CB)
