Caryomyia hirtiglobus
Hickory Woody Globe Gall Midge
Caryomyia hirtiglobus is a gall midge in the family Cecidomyiidae, described by Gagné in 2008. The species induces woody, spherical galls on hickory trees (Carya spp.). It is one of several Caryomyia species associated with hickory, with its specific epithet 'hirtiglobus' referring to the hairy, globe-shaped galls it produces. The species has been documented in eastern North America where its host hickories occur.
Odontocynips nebulosa
root gall wasp
Odontocynips nebulosa is a cynipid wasp that induces large, woody, subterranean galls on oak roots. Adults are small and rarely observed; the galls are the primary sign of its presence. The species was long misidentified due to confusion with a different gall-former on oak leaves. It has a two-year life cycle and is restricted to the southeastern and central United States.
