Cecidomyia? racemicola
Rhopalomyia racemicola
Gall. Green, smooth, rounded, tapering to a point at the apex, giving it a bud-like appearance. Inside it is hollow and contains a single larva. Length about 3 mm and 2.5 mm in diameter.
Found singly, or in clusters, among the racemes of different kinds of goldenrod (Solidago canadensis [sense unknown], puberula, serotina [gigantea] and probably other species).
Habitat: NC, NY, DC
The galls may be found in September and are somewhat difficult to detect, owing to their resemblance to the buds of the goldenrod flowers. The larvae leave the gall in autumn and enter the ground to transform.
