Genus Evagetes
Numbers
10 species in North America.
Size
Generally 8-22 mm; females slightly larger than males.
Identification
This genus belongs to the subfamily Pompilinae, tribe Pompilini and is identified by the following characters:
Spines at apex of hind tibia of unequal length and spacing.
Hind tibia always smooth in nearctic species.
Dorsal side of hind femur with at least a few spine pits.
Pocket in the basioposterior corner of the third discal cell.
Labrum at least partially concealed.
Females of this genus possess a tarsal comb.

In Evagetes:
The antennal segments are very short, less than 3X as long as its greatest width.
Postnotum not broadly widened laterally.
Pygidium of females lacking stout bristles.
Jugal lobe small, scarcely more than half the length of the submedian cell (compare Chalcochares.
Pronotum rather long compared to other pompilini, with a distinct dorsal face.
Range
Transcontinental as a genus.
Habitat
Varied, wherever hosts are found (see Life Cycle).
Season
Typically found from early summer through early autumn (June through September or October), usually longer in the south.
Food
Adults commonly visit flowers. Young eat the spider prey of their host wasp (see below).
Life Cycle
Evagetes are social parasites of other pompilidae. They will find a host (they are usually host specific and in many species the host is not known), dig into the nest, eat the hosts egg and lay one or their own.
