Very large wasps, not quite rivaling Pepsis or Hemipepsis, but most exceed 20 mm and some may attain lengths of almost 30 mm.
Large size is one of the best clues.
More technically they belong to the subfamily Pepsinae, tribe Pepsini which is defined by the following characters: groove in 2nd sternite, crease on side of 1st tergite marking off an epipleuron, serrate hind tibiae, at least a partially exposed labrum, concave sides of 1st tergite (look dorsally), spines on end of hind tibia of equal size and spacing.
Subtle wing venation and other characters used to separate genera and species, see Townes(1)(1957) for this information (and keys plus brief species descriptions/discussions).
The genus is found practically transcontinentally but some species have restricted ranges.
Open areas, woodland edges; never found in deep woods.
found later in the season (late summer-early autumn)
Adults frequently visit flowers, especially umbellifers and Solidago spp. Adults provision a pre-existing cavity or modification of a pre-existing cavity with a Lycosid spider.
Life Cycle
one generation per year in most of the US
