Caryomyia lenta
Gagne Description 2
Occasional, on Eucarya hickories, not found east of the Appalachian Mts (Map 2); on lower or upper (one example) leaf surface between veins; height 3.3- 5.0 mm, depressed-spheroidal, sometimes conical, with small nipple or tiny opening at center apex; rough textured, sticky, hairless, light green turning brown; base with central conical pedicel, leaf with raised, wide, mucilaginous, brown ring surrounding connection with gall and on reverse side showing discolored, hardened convexity; wall thin, rubbery, larval chamber surrounded laterally and apically by much larger, false chamber, the chambers separated by hemispherical, thin, sticky wall, both chambers longitudinally striate. The one instance of a gall on the upper leaf surface (Amston, CT) occurred on a leaf that also had a gall on the lower surface. This gall is superfically similar to that of C. inflata except that the present gall is extremely sticky to the touch and its false chamber nearly completely surrounds the top and sides rather than sits atop the larval chamber.
