Caryomyia purpurea

Gagne Description 2

Common, found on Eucarya hickories; on lower leaf surface, usually found in groups between veins but may occur close to veins; 2.2-3.0 mm in height, spheroidal, occasionally with slight, conical prominence at apex, surface covered with long, thick, mostly dark brown hair obscuring gall surface; base with deep, circular, central excavation, the leaf without exfoliation surrounding connection; wall woody, of even thickness but thicker apically if peak present, green to brown; larval chamber at base of gall ovoid, violet to purple. Exteriorly, the more conical galls are similar to the more short-conical galls of C. holotricha; such galls must be cut open to see whether hairs intrude into the larval chamber from the apex as they do in galls of C. holotricha.
