Feron gigas
Saucer Gall Wasp
Feron gigas, the saucer gall wasp, is a cynipid wasp that induces distinct galls on oak leaves. It exhibits an alternating generation life cycle with morphologically different galls produced by all-female (agamic) and bisexual generations. The species is associated with several oak species in western North America and has been widely documented through citizen science observations.
