Digger Wasp

Dear Sharon,
This is a solitary Digger Wasp,
Scolia dubia, and it is not an aggressive species.  They develop underground, but they are not social wasps with hundreds of members of a colony.  According to BugGuide:  “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.”  Any insect that preys on the invasive Japanese Beetle is a friend to the gardener.  We do not provide extermination advice.
