An incorrect identification may be followed without the error being recognized for considerable time.
In case that happens with a common species, the first image in bugguide bearing the wrong ID is soon tailed by several others:

37 images, until now, had been sampled under Anthrenus flavipes, evidently none of them showing the species! For the most part, images show the similar species A.verbasci. The basic ID seems to be one from Mr.Kingsolver on an image, that in itself is insufficient for species ID, because the critical characters cannot be seen:
I like to excuse Mr.Kingsolver immediately, because in the web (and probably in collections also) there are plenty of A.verbasci labeled as A.flavipes - a species, by the way, not listed by Nearctica(!), and still to be found for the guide.
For the sake of the growing importance of bugguide as information source I have rearranged the images, and included diagnostic information on the species pages. Error not perpetuated any more!
