Natural history | |
Phaeogenes ater is believed to be a soliatry parasitoid that is specific to clearwing (Sesiidae) hosts. Host records include Synanthedon pyri , S. scitula, S. tipuliformis, S. exitiosa, and Podesia syringae (Heinrich, 1977). Phaeogenes ater has also been reared from Podosesia aureocincta (the banded ash clearwing) (Purrington and Nielsen, 1987).
Two pupae of Synanthedon exitiosa, collected by the author, produced two solitary adult female specimens of Phaeogenes ater. These were collected from a commercial orchard in Blue Ridge, Georgia on 4-VII-2007, with an adult emerging on 7-VII-2007 and 21-VII-2007. Dr. David Wahl (American Entomological Institute, Gainsville, Florida) confirmed the identity of these parasitoids.
