fragment of a dead insect

5899  Found a few under my mattress. I came back from Costa Rica less than a week ago, and have been getting bites around my hands, ankles, a few on my chest. Standard red and itchy…. I have not seen any live bugs yet. Thought they were bed bugs at first, but I had them a few years ago, and was not affected by their bites.    thanks,  Justin

This is a fragment of a dead insect, possibly a larva of a beetle in the family Dermestidae (hide/skin/larder/carpet beetles and allies). Ed Saugstad, retired entomologist; Sinks Grove, WV.
