Digger Wasp

Hi Jim,
This is a Digger Wasp or Blue Winged Wasp,
Scolia dubia.  Female Digger Wasps prey upon the grubs of Green June Beetles and Japanese Beetles in order to provide food for her brood.  For that reason, Digger Wasps should be considered beneficial and there presence should be tolerated in the garden.  Adult Digger Wasps feed on nectar, and since they are solitary wasps, they are not considered aggressive.  It is possible that one might be stung if an attempt is made to handle a female Digger Wasp.  Male Digger Wasps cannot sting.  For more information, you should see BugGuide.
