Caryomyia eumaris
Gagne Description 2
Common, found on Eucarya hickories; usually single or scattered, attached to small veins on lower leaf surface; 2.2-2.7 mm in length, recumbent, subovoid except for apical, curved, tapered extension; rough textured, white, green, to tan, with short, sparse, white hairs not obscuring surface; base of gall with short, central conical projection surrounded by shallow, circular indentation; wall firm, brittle, uniformly thin, larval chamber glabrous with longitudinal ridges following gall axis from leaf vein connection to recurved apex. This gall is most similar to that of C. recurvata but has a rough surface with sparse hair. The gall of C. recurvata has a hairless, smooth, glaucous surface
Gagne Biology Note 2
In mid-June in central Maryland, galls are small to full-grown, green and soft, and contain first instars. By end of June through August, most galls examined contained second instars but a few still had first instars. By end of August galls mostly contained third instars and many galls were turning or had turned red.
