Questo coleottero di circa 3 millimetri di lunghezza è rimasto intrappolato nella finestra di un hotel, in un ambiente rurale. Qualche idea di cosa potrebbe essere? Forse Nitidulidae?

Reesa vespulae (Mill., 1939), Dermestidae

Infinite thanks!!!!! I never heard before about this genus of dermestid beetles! Are they wasp parasites? (vespulae) German wasps are extremely common in this zone!

The specific epithet "vespulae" derives from the fact that the first specimens of this species were collected from a wasp nest in the USA. Today, Reesa vespulae is considered a pest of museums, because its larvae feed on dried insects and specimens of other animals. Today, It's a cosmopolitan parthenogenetic species and only females are known for this species.
They could be simbionts of wasps... At the moment, I couldn't say if, sometimes, they could be parasites of these insects.
