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.
