Eighty-one species of primarily ground-nesting solitary wasps belonging to the families Tiphiidae, Pompilidae and Sphecidae were observed, collected and identified from six sandy and gravelly study areas in Cayuga and Onondaga Counties, New York. The observations and collections were made 1 September-3 November 1966,1 September-l November 1967 and 13 September-29 October 1984, with some species (Ammophila urnaria, Diodontus franclemonti) nesting through the entire months of September and October. An attempt to associate extended flight season with overnight resting site, geographic distribution, taxonomic affinity and prey type is made, but only the association with prey type appears to have any validity.
