Caryomyia viscidolium
Gagne Description 2
Occasional, found on Eucarya hickories; on upper leaf surface, between veins; 3.0-4.1 mm in height, spheroidal, longer than wide, base broadly rounded to truncate in profile, apex with small central nipple surrounded by extensive areola that eventually separates from gall; surface resinous, especially on young galls, sticky, smooth except for scattered minute resin dots, areola paler than surrounding surface; base with wide, deep, circular indentation; wall firm, brittle, almost uniformly thin, larval chamber glabrous, with longitudinal ridges. This gall and that of the unrelated C. turbanella are the only Caryomyia galls that occur exclusively on the upper leaf surface of hickories. For notes on galls of related species, see under C. cilidolium.
Gagne Biology Note 2
Pupae break out of the weak cap at the gall's apex. Emergence occurs in April.
