Yes, Katy. You can see that the body shape, scale pattern and scale morphology are the same in those photographs. Scales get rubbed off over time, especially when they try to push into narrow places. More recently eclosed adults might have a somewhat pale body integument to start. Other Anthrenus species have different scale morphology, pattern and other coloration differences, too.

(I have logged them as Anthrenus verbasci though am open to correction). My question is less about identification and more about threat level. The three beetles in the attached images were found in traps on two different levels of the museum each at least a year apart. I put down additional traps in the area each time I came across one and never came up with any more beetles or their larvae. I assumed they were incidental, brought in on the clothing of our visitors. Looking back at my photos though I began to wonder. The first two images are from May of 2018 and March 2021 and the pattern on their elytra(?) looks nearly identical to my novice eyes. Our third specimen, found in July of 2019, strikes me as very similar also but a bit “paler” in its coloring. I don’t know much about these insects beyond what their larvae can do to our collection. Are similar patterns indicative of some localized “family” of beetles somewhere in our building? Or would any member of this species have such a pattern? Most importantly, is there anything else I can do besides laying down additional traps and monitoring more frequently to assess the actual threat level these specimens represent? Any insight is much appreciated.
