Caryomyia antennata
Gagne Description 2
Occasional, on Eucarya hickories; on or closely adjacent to veins of lower leaf surface; 3-6 mm in height, spheroidal, usually tapered to conical apex, covered with moderate to thick, white to tan hair not quite obscuring gall surface; base with central hemispherical pedicel fitting into corresponding leaf depression, some short exfoliation of leaf surrounding connection; wall woody, uniformly thick, larval chamber narrowed at both ends, with longitudinal ridges. This gall could be mistaken for one of the less hairy C. holotricha or C. aggregata galls, but galls of those species have a basal excavation rather than the prominent hemispherical connection to the leaf of the present species. The larval chamber of this gall is unique in that it extends into this connection.
Gagne Biology Note 2
First noticed as full-size, hard galls in eastern West Virginia in early July, all were inhabited by second instars. By early August galls contained either a second or third instar. Full-grown larvae fully fill the larval chamber.
