Appearance
It is similar in shape and colour to the steel-blue cricket hunter. Like other types of wasps, males do not have an ovipositor, and therefore cannot sting. It is ranged from northern Mexico to southern Canada, including most of the United States. It has also been introduced to regions including Hawaii, Bermuda, Croatia and other European countries.Naming
This species is most famous for its predation of black widow spiders. Adults feed on the nectar of flowers, which powers their flight. They pollinate some common wildflowers, including "Berberis vulgaris", "Daucus carota", and "Zizia aurea". Larvae are fed spiders, often "Latrodectus mactans". They prefer to hunt prey on the ground or under rocks.Behavior
Females can build their own nests, but often refurbish nests abandoned by other wasps and bees, particularly those of "Sceliphron caementarium", removing any spiders captured by "S. caementarium" and the larva, replacing it with an egg of its own and freshly caught spiders. They go through multiple generations in a year.References:
