maleblackwaspLife history:

These wasps do not make a communal nest, but often form small swarms over an area of turf, a compost heap or around a shrub. They can also been seen taking nectar at flowers. The females burrow into the soil to locate scarab beetle grubs, which they sting and lay an egg on; the resulting wasp larva consumes the scarab, to emerge the next season as an adult wasp.

Pest Status:

Females can sting but rarely do, as they are not aggressive. Potentially beneficial as predators of scarab grubs.

Control is not necessary. Ignore them.
