Caryomyia marginata
Gagne Description 2
Infrequent, on Eucarya hickories; on lower leaf surface, between or on veins; length 3.2-5.0 mm, conical, the base flat against leaf surface, circular, with flattened lip surrounding cone that gradually and evenly narrows to pointed apex; green to tan, smooth, covered evenly with long, sparse hairs not obscuring surface; base with narrow, shallow, circular, central excavation, the leaf without exfoliation surrounding connection; larval chamber ovoid, located at base of gall, surrounded by woody tissue. This conical, sparsely haired gall is most similar to that of C. conoidea but the sides of the cone of the C. marginata gall are concave and the basal angle is acute and marginate. This gall is entirely woody unlike that of C. conoidea, which is partially filled with soft tissue that eventually collapses.
