Asphondylia photiniae
North American-inducing insect
Asphondylia photiniae, also known as the toyon fruit gall midge or toyon berry gall midge, is a species of midge that induces galls on the developing berries of the toyon bush in North America.[1][2] Galled berries stay green (when other fruit has ripened to red or gold, etc.) and look somewhat warped.[2] Each galled berry contains a single larva, which emerges in spring.[2] This midge is known from the Californias, where native Heteromeles arbutifolia grows in relative abundance.[1]
