Ageniella accepta
This record describes Ageniella accepta (species). Recorded family: Pompilidae. Recorded order: Hymenoptera.
Identification and Appearance

♀ ♂ Like all Ageniellini, they sever the legs of their prey to accommodate transport: This photo shows either an aberrant A. accepta or (less likely) an undescribed species

Habitat and Range
Habitat
Open areas are favored (i.e. fallow fields, sand barrens, and other places with bare soil and sparse vegetation). Also hunts at woodland edges.
Geographic Range
Transcontinental, southern Canada to Mexico
Seasonal Activity
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.
Diet and Behavior
Diet: Adults occasionally visit umbellifers and other similar-structured flowers. Nests are provisioned with Lycosid spiders.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Ageniella accepta. Species-specific details appear above.
Group overview
Hymenoptera includes over 150,000 described species of ants, bees, wasps, and sawflies. Earth harbors approximately 20 quadrillion (20×10^15) ants, with a combined biomass of ~12 megatons of dry carbon - exceeding the combined biomass of all wild birds and mammals (PNAS, 2022).
Ecological role of the group
About 35% of the world's food crops depend on animal pollinators. The chocolate industry, valued at over $100 billion, depends on pollinating flies and midges. Ants are the dominant soil engineers in most terrestrial ecosystems, turning more soil than earthworms in many habitats.
Economic and practical significance of the group
Pollinators contribute $235-577 billion worth of annual global food production (FAO). In the U.S., bee pollination alone benefits crops valued at $18 billion annually, and honey bees are responsible for $5.4 billion in agricultural productivity. Between April 2023-2024, 55.1% of managed honey bee colonies were lost. The U.S. bee population dropped from 5 million to 2.5 million.
