Dasineura investita
Wood Nettle Gall Midge
Dasineura investita is a gall midge in the family Cecidomyiidae that induces distinctive galls on wood nettle (Laportea canadensis). First described in 2016, this species produces oval to globose galls measuring 4–5 mm by 8–12 mm on various plant parts including petioles, leaves, leaf midribs, leaf veins, flowers, and stems. The galls exhibit variable coloration ranging from pale and white to red and green translucent. The species has two generations annually, with autumn-generation larvae overwintering inside the gall's central chamber.
