Abstract

Recent (2024) photographs of Pepsis elegans Lepeletier (Hymenoptera: Pompilidae: Pepsinae) females searching through plant litter disclosed no clues about its nesting behavior or host spider. However, coupled with geographic site locations, they reveal important habitat information. The various site locations are specifically defined as part of the Eastern Temperate Forests Level I Ecoregion of North America, numerous Level III Ecoregions of the Continental United States, several U. S. Forest Type Groups, and natural habitat designation of mesic open woodland.
