About Asphondylia photiniae Pritchard, 1952
Asphondylia photiniae, commonly called the toyon fruit gall midge or toyon berry gall midge, is a species of midge. It induces galls on the developing berries of the toyon bush in North America. Galled toyon berries remain green, even when other toyon fruit has ripened to colors like red or gold, and they have a slightly warped appearance. Each galled berry holds a single larva of this midge, which emerges in spring. This midge has been recorded from the Californias, where its native host plant Heteromeles arbutifolia grows relatively abundantly.
