Clothes moths will eat more than our wardrobe. Given a chance, they'll eat us too.
Casemaking clothes moth caterpillars can digest human hair and will feed on corpses. But it's not all bad news, scientists say.
Hair bits nipped off of corpses by caterpillars of the casemaking clothes moth, Tinea pellionella, can yield enough DNA to identify the deceased, according to entomologist Sibyl Bucheli of Sam Houston State University in Huntsville, Texas.
Particularly helpful is the caterpillars’ habit of retreating to nearby, out-of-the-way corners when it’s time to stop feeding and metamorphose into small tan moths, Bucheli reported November 16 in Reno, Nev., at the annual meeting of the Entomological Society of America. The human body they’ve been feeding on may get moved away, but left-behind caterpillar cases containing human hair can still tie the body to the location, she said.
Casemaking clothes moths rank among the two major wardrobe attackers in North America, though the species remains more of a rural dweller than an urban one.
Scientists have discovered clothes moths nibbling on a corpse before, according to Bucheli. And clothes moth larvae in the wild will graze on a dead animal. “They had to eat something before people invented wool sweaters,” she said.
What’s new is the human hair in the home of the casemaking clothes moth caterpillar. This species takes its common name from the half-inch long, skinny, fiber-fuzzed cases that young larvae build.
Youngsters create the case with one end open, nestle inside and then crawl around in search of food. They feed by sticking out their front ends partway, like chilly campers refusing to climb all the way out of warm sleeping bags. As the caterpillars grow, they enlarge their cases, incorporating bits of nearby fibers into their portable homes.

I’m a wooly worm man myself.
So, how long will the winter be? :’)
