Synonyms and other taxonomic changes
A fairly recent genetic study by Cecilia Waichert, Carol von Dohlen, and James Pitts found the three "species" in the Ageniella accepta species group to be composed of a single widespread, morphologically highly variable species. The name with taxonomic priority is Ageniella accepta, so A. conflicta and A. blaisdelli are now synonyms of A. accepta.
Females are entirely orange or red-orange.
Wings range from pale straw-colored with two very distinct bands to almost entirely dark. However, the wings usually show at least some indication of banding even in individuals with very dark wings.
The brush on the inner side of the hind tibiae in interrupted subapically and the marginal cell is separated from the wing tip by its own length or less.
The hind tibiae of both sexes are smooth.
Transcontinental from southern Canada south into Mexico.
Open areas are favored (i.e. fallow fields, sand barrens, and other places with bare soil and sparse vegetation). Also hunts at woodland edges.
Fairly rare so its seasonal distribution is difficult to assess. Seems to have a single generation in the northern states with adults on the wing from mid-July to mid-September. Possibly a much wider flight season and an additional generation in the extreme southern U.S.
Adults occasionally visit umbellifers and other similar-structured flowers. Nests are provisioned with Lycosid spiders.
Like all Ageniellini, they sever the legs of their prey to accommodate transport:

This individual is probably an aberrant A. accepta, although it could possibly be an undescribed species:
