Hickory Bumpy Woody Gall Midge
Caryomyia tuberculata
Gagne Description 2
Common, on Eucarya hickories; often in groups, on lower leaf surface between veins; 3.5-5.1 mm in height, depressed-spherical to spheroidal, occasionally with slightly pointed apex; surface hairless, bumpy, sticky, green, yellow, or brown to almost purple; base with large, central, deep, circular ex- cavation, leaf without exfoliation surrounding connection; wall uniformly thick, woody, larval chamber ovoid, floccose, white, green, to purplish. The gall is most like that of C. purpurea because of its shape, the thick, woody wall, and the leaf connection but, unlike that of C. purpurea, is bumpy and hairless.
Gagne Biology Note 2
Tiny, yellow-green, soft galls containing first instars were first noticed in central Maryland on June 10. On June 22 new and full grown galls were found on the same leaf, with first and second instars, respectively. Galls found from late June through mid-August contained second instars, after which third instars were reg- ularly found. The full-grown larva fills the larval chamber. Adults emerge through a hole in the side of the gall
