Dermestes haemorrhoidalis

This is a close relative of the preceding species which also lives on dried animal remains. Larvae ready to pupate have the same habit of gnawing their way into all kinds of materials.

This is a recent addition to the European fauna, but it appears to have become quite common, particularly in large towns. The adult beetles fly very well and so an odd one may appear in any house. In general, they can do no damage in a normal household, but they may multiply if the remains of food and other kitchen waste are left lying around for months. In many cases the beetles come from a pigeon’s nest.
