Rank Reasons
This species has a large range, many occurrences, and populations appear to be relatively stable over the long-term.
Range Extent Comments
This species occurs in southeastern Canada from Ontario to Nova Scotia and in the United States from Wisconsin to Maine, south to Florida and west to Arizona, and north to Utah and Nebraska (Freeman and Perkins 1992; Lewis 2005; Waggoner et al. 2006; Dourson and Feeman 2006; Hotopp and Pearce 2007; NatureServe 2025; RARECAT 2025; InvertEBase 2025).
Occurrences Comments
This species is known from > 1900 occurrences using a 1 km separation distance and records from 1994-2025 (Freeman and Perkins 1992; Lewis 2005; Waggoner et al. 2006; Dourson and Feeman 2006; Hotopp and Pearce 2007; NatureServe 2025; RARECAT 2025; InvertEBase 2025).
Threat Impact Comments
Too frequent burning likely threatens this species, at least in grassy woodland habitats (Brand et al. 2020).
