Neither dermestids nor clothes moth larvae eat silk. Silk has no keratin (animal protein) in it. The text books are wrong. If dermestids or clothes moth larvae damage silk, they inadvertently do so as they graze on the sizing. Silk threads are so fine, the larvae may damage them, but they are not "feeding" on the silken threads. They simply chew through them as they forage of the sizing. Wool, horse hair, whale baleen, porcupine quills, embroidery, etc. all have keratin and will support fabric pest larval development.

It would be worth checking any upholstery containing these materials for damage.

It looks like they are a click beetle (Elateridae), a type of darkling beetle (Tenebrionidae), and another one I can't quite make out. The larva appears to be an Odd Beetle. It's one of those strange dermestid beetles, whose larvae feed on protein materials.

I am fairly new to insect ID and would love a little help identifying the bugs. I have attached some (admittedly pretty poor) photos and would appreciate any insight you might be able to share. Thanks very much! Whitney Robertson Whitney A. J.
