Hickory Awl-shaped Gall Midge
Caryomyia subulata
Gagne Description 3
Occasional, on Eucarya hickories but not east of Appalachian Mts; usually in scattered groups, on lower leaf surface between veins; length 6.0-9.0 mm, elongate-cylindrical, erect, slightly bowed, tapered to pointed apex; shiny, brown, becoming black; base of gall deeply recessed, and set into socket formed from thick, scabrous, leaf growth with sharp apical edge; larval chamber occupying full length of gall, green, longitudinally striated, the wall firm, brittle, uniformly thin. This gall superficially resembles that of C. tubicola but the apex of the present gall is tapered rather than blunt and its base is deeply recessed rather than conical.
