Lasioptera clavula

Cecidomyia clavula

Gall.--On the terminal twigs of dogwood (Cornus florida). It is club-shaped and about 0.5 to 1 inch long. Inside is an elongate channel inhabited by one or more larvae.

The larvae leave the gall in September and October and enter the ground to transform. They overwinter and the adults emerge during May and June.
