Evania appendigaster
Cockroach Egg Parasitoid Wasp
Not native to Florida
Common in Florida and across the southern United States to California. Also present in New York, Pennsylvania and Ohio. Believed to originate in Asia.
Members of this family have a small flatted abdomen connected with a thin petiole near the top of the propodeum. This abdomen appears somewhat like a flag and is the source of the family common name of ensign wasps. The large size helps identify this species. Evania appendigaster has forewings 5.5-7mm (3/16 to 9/32 in.) in length. Other species have forewings of 5mm (3/16 in.) or less.
Often found in homes and businesses, this wasp is parasitic on the egg cases of American cockroaches.
Evania appendigaster is a member of the Evaniidae - Ensign Wasps family.
