Scientific name: Scolia sp. Region: Throughout North America and Europe
Life cycle: Normally a single brood per year.
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.
When it locates a grub, it parasitizes it (often killing it with its powerful sting). In some cases she will burrow deep into the soil (up to four feet) dragging the grub behind, before forming a nest cell around the host and implanting an egg.
