Food
Adults take nectar, may also feed on juices from beetle prey. Larvae are parasites of scarab beetles.
Life Cycle
Males and females have a courtship dance, flying close to the ground in a figure-8 or S pattern. Females burrow into ground in search of grubs, especially those of Cotinis and Popillia japonica. She stings it and often burrows farther down, then constructs a cell and lays an egg on the host. Larva pupates and overwinters in a cocoon within the body of the host. One generation per year in North, more in South.
Remarks
Males have a 3-pronged "pseudostinger," a part of copulatory gear
