Dermestid beetles sexes

How do you tell the difference between a male and a female flesh eating beetle? (dermestid beetles)

It will depend on which species you are looking at; how you tell males from females is different for every species (color, antennae, horns, bristles etc.). For example, in some species of dermestid beetle, like the ones used in skeleton preparation (Dermestes maculatus), the females are generally larger than the males. Also in some species, the very last segment of the antennae are much longer in males than in females.
