chokecherry midge, chokecherry gall midge
Contarinia virginianiae is a gall midge species in the family Cecidomyiidae that induces galls on chokecherry (Prunus virginiana). The larvae feed on developing fruit, causing enlargement and hollowing of the fruit into a pear-shaped gall. The species was described by Felt in 1906 and occurs in northern North America where its host plant is native.
