Osmoderma eremita, the hermit beetle or Russian leather beetle,[2] is a species of European beetle in the family Scarabaeidae. Adults reach between 28 and 32 mm in length.[3]
The larvae develop in hollow trees. Oak is the preferred kind of tree, but the larvae may develop in any tree species with suitable hollows.[2] Due to extensive scientific research, O. eremita is the most well known insect species associated with ancient or hollow trees. For instance, research has addressed the beetles' dispersal biology,[5] population dynamics,[6] and chemical communication.[7] Trained conservation detection dogs are being used in monitoring larvae in Italy.[8]
