Angelica - For a thorough treatise detailing this moth, its biology, and habits go to: https://entemdept.edu>creatures>urban>occas This is the website of the University of Florida Entomology Department, the members of which encounter this moth routinely. I have worked with it in several locations in museums in Florida. Vacuum, vacuum, vacuum. The larvae love to feed on spider webs. Tom Parker

Thomas, we're in Lima, Peru. The museum is about 30km south of the city. These are our rough what3words coordinates. The climate is akin to San Francisco, with a desertic coast but constant cloud cover and common fog. Thank you, Tony. Yes, I am very wary of Google photos since I never know for sure what they're showing. Thank you for your thoughts! I just found on an entomology page from the Univ. of Florida that Phereoeca are actually parasitised by Apanteles carpatus, which we have had identified by an entomologist in our stores, so this is great news.

Please be wary of Google photos - many of the identifications are incorrect - you need to be doubtful of any that are not posted from an experienced entomologist.

I recently came across a moth I hadn't heard of before called Phereoeca uterella or plaster moth / household casebearer and it suddenly struck me that perhaps the case moths I am used to finding at work are in fact that and not the T. pellionella that I thought. Unfortunately for me, the fact sheet for P. uterella doesn't seem to be up on the museum pests website yet. I had always wondered about this ID because we find a lot of our cases stuck to our poured concrete walls even in spaces where there are no exposed objects. I wasn't sure what they were eating. The cases have this grainy quality under the microscope which doesn't look like threads or wool-derived, and the cases are rather flat instead of tubular (pumpkinseed shaped, as described on Wiki). The cases we find are always white or very light grey. We also tend to find them grouped around the other insects in our traps, suggesting they are eating the bodies of the dead insects. This said, I don't believe I have ever, in 5 years, seen a moth in our traps that looked as dark as the P. uterella adult according to the Google photos. I attach a few images. Any thoughts will be greatly appreciated.
