Desert Diary Desert Diary
Mankind utilizes the services of all sorts of animals. You know many of them, from chickens to cattle to horses to lab mice. Then there are some not so familiar, such as falcons used for hunting. There are others you know of, but probably aren't apt to have come to mind, like bees. But there's probably not one person in a thousand who would tie together natural history museums and dermestid beetles.
If you're in the habit of turning over dried up carcasses in the wild, you're probably familiar with these small insects. The name comes from words meaning eaters of flesh, which
may give you some idea as to why you find them in carcasses and museums. Many natural history museums collect animals as part of their scientific investigations. The study of skeletons is a worthy
endeavor in its own right, but mammalogists, especially, need skulls for identification and evolutionary studies. Thus many such a museum houses a colony of dermestid beetles, whose larvae delight
in delicately nibbling flesh from bone. To each their own, I always say.

Adult and larval dermestid beetles. The larva is the worker; the adult's role is to produce more larvae.
