Daphnephila ornithocephala is a species of gall midge first associated with leaf galls on Lauraceae species, particularly Machilus thunbergii in Taiwan.

Based on analysis on sequences of the mitochondrial cytochrome c oxidase subunit I, it has been suggested that in this genus, the stem-galling habit is a more ancestral state as opposed to the leaf-galling habit.

This genus appears to have originated tropically and dispersed to Japan through Taiwan.
