Wasp Series

Wasp Series
Thompson Falls, Sanders County, Montana, USA
September 10, 2006
I am thinking that this might be what killed the larvae. It looks similar to a carpet beetle larva. I found it inside the cells and every larva in that nest was dead.

Dermestidae.
It is indeed the larva of a dermestid, though I'm not sure which genus (NOT Anthrenus). It would not have killed the larvae, but probably would have eaten the dried-out spider remains.
