broad-winged tree cricket
Nest of Isodontia auripes, a grass-carrying sphecid wasp that often stocks its nest with paralyzed tree crickets. This nest, stocked with at least a dozen Oecanthus latipennis, was found on the upper surface of a porch rail, beneath a door mat that had been draped over the rail for some time. Franklin County, Missouri.
