The life history of this species is described and the galls and cocoons figured by Breland and Schmitt under the name Bucculatrix fusicola Braun. The galls are somewhat variable in shape (as figured) often appearing as a swelling on the side of the stem. The larvae become full-fed in the fall passing the winter in the larval state within the gall, leaving the gall to spin and pupate in the spring; a raised ring may encircle the exit hole of the larva.
