Definitely coffin flies. These can be indicative of a broken sewer pipe or a dead critter. If they are present in an area with a drop ceiling I would inspect there. Inspect any crawl spaces or basements for broken or seeping lines. Check for bodies. Any odd smells nearby?... could be a funky floor drain.

I'm not sure, but the first one seemed a little different to me in the wing pattern, and the antennae seem thicker, not so coincident with those of the others. may be? kind regards, Nelci El jue, 27 jul 2023 a la(s) 11:00, Günther, Christina (guent...@snsb.de<mailto:guent...@snsb.de>) escribió: Hello! I´m responsible for the IPM at the Bavarian State Collection for Palaeoanatomy (Munich, Southern Germany) and since a couple of weeks I noticed an increased appearance of some sort of fly or wasp in our traps. The insects are about 1 to 3mm in length (body), most of them range between 1 and 2mm. My pictures aren´t good, I know. Maybe somebody can help me with the identification in spite of their quality. Thanks a lot for your time, Christina Günther Technical assistant at the Bavarian State Collection for Palaeoanatomy -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
