gall

Spindle-shaped swelling of a young branch, gradually narrowing at both ends, not unfrequently several in a row. The larva is distinguished from those of Rabdophaga species (Cecidomyiidae) by having a black of dark brown cephalic skeleton (more easily visible when the larva is seen from the side). The puparium is yellowish but the anterior segments are bright reddish brown and conspicuously sloping ventrally (Spencer, 1976a).
