Sphecid nest? - Sceliphron caementarium Hancock County, Indiana, USA June 19, 2011
Upon return from vacation, a wasp had built a mud nest on the floor of the garage. I saved what was left after it was run over. There are several larva and/or eggs, and one of the larvae seems to have a parasitoid on it. The cells were elongate, about an inch long (just a guess from memory). There were three cells and most of the entombed spiders are visible here. Some are still visibly twitching.
Would this have been a sphecid nest, or are there other wasps that provision with spiders? What might the parasitoid be? Will the parasitoid develop if I place it, a larvae or two of the wasp, and some spiders in a small closed container?
To our spider enthusiasts, if you'd like to see a close-up of any of the spiders let me know.
These images can be frassed if not needed.
