Dear pestlist-members Thank you all for helping me in identifying the beetles. As you all tried to help me, I'd like to let you know what we find out. Yesterday we looked more closely at the beetles and the holes they are making in the wood – and we’ve even seen one of the beetles just trying to make a hole in the wood. As far as we know now, it is a wood-boring beetle and it must be a leperisinus varius. Amongst them, it could be, that we have a few Anthrenus (or something similar) – but they don’t seem to be the ones of which we have thousands. And we don’t have the beetles inside the display cases – except maybe one or two near a bird’s nest - so this could be one of the few Anthrenus. But we have a lot more of the leperisinus varius. Thank you again and best regards from Switzerland Elisabeth Abgottspon -----Ursprüngliche Nachricht----- Von: pestlist-ow...@museumpests.net [mailto:pestlist-ow...@museumpests.net] Im Auftrag von Jones, Lynn Gesendet: Mittwoch, 7.

The way the head is tucked at a right angle to the body, the clubbed antennae, the mottled elytra, and the piles of powder; I too agree these are not Anobium punctatum, nor are they Dermestids. I have no idea what they might be.
