Overview of our fauna:
Abdomen long and stalked (petiolate), giving the body a "thread-waisted" appearance; middle tibiae with two apical spurs; body may be all black (sometimes tinged with metallic blue or green), black and red, yellow and black, or white and black. Males have no tarsal rake, 11 flagellomeres, and 7 gastral segments. Females have a tarsal rake, 10 flagellomeres, and 6 gastral segments.
Sceliphrinae: Chalybion wing venation
Chloriontinae: Chlorion wing venation
Sphecinae: Prionyx (left, Prionicini), Isodontia (center, Sphecini), Sphex (right, Sphecini) wing venation
Ammophilinae: Ammophila wing venation
Most species nest in the ground, usually in areas with sparse or no vegetation; some build aerial nests of mud; a few nest in hollow stems or abandoned bee burrows in logs
Larvae feed on paralyzed arthropods (the host varies according to wasp species) provided by adult; common hosts include spiders, grasshoppers, and caterpillars. Adults feed on nectar from flowers and extrafloral nectaries, honeydew, and body fluids of their prey.
most are solitary nesters; some species are kleptoparasitic, using prey caught by other wasps in order to provide it to their own larvae.
