Pelecinid Wasp

Pelecinid Wasp – Pelecinidae – Pelecinus polyturator.  Millstream Gardens Conservation Area, Madison County, MO.

Parasitoids of insect larvae, the Pelecinid Wasp female uses her extremely large abdomen to thrust through soil to deposit eggs primarily on scarab beetles.  I assume the family and genus names are derived from the Greek – pelicos, referring to the great size of the wasp.  Females can reach lengths of up to 6 cm.  No need to worry, these guys do not have stingers.
