Three nests of Crabro advena from near Chittenango, Madison County, NY were excavated, examined, measured, and drawn. The cell contents were taken to a laboratory, analyzed, weighed, and sent out for identification. Adult Tachinidae comprised the major prey type captured by the wasps. This study further extends the ecological and behavioral variation of C. advena. Information on nesting season, soil type, number of cells per nest, cell depth, number of prey per fully provisioned cell, and prey type from this and five other upstate New York studies are compared.
