Scientific name:  Scolia sp. Region:  Throughout North America and Europe

Physical Description:  These Wasps are large solitary wasps about .5 - 2 inches long.  The Adult is Hairy, black, with bright red and yellow markings on the abdomen.  The wings are black

Feeding characteristics:  "The Grub Killer." Scolia Wasps are mainly external parasites of Coleoptera.  The adult female burrows into the soil in search of grubs.
