The immatures induce a closed, light-to-dark green gall (Figs 281–286). The galls are globular (Fig. 281) or conical (Fig. 282) on the adaxial leaf side, and tubular with many white trichomes apically (Fig. 283) on the abaxial leaf surface. All dissected galls were unilocular and each contained a single immature. After adult emergence, the galls undergo gradual desiccation while the leaf remains attached to the plant.
