Cecidomyia fraxini Bremi, 1847Perrisia fraxini Kieffer, 1897 Dasineura fraxini is a gall midge which forms galls on the leaves and petioles of ash (Fraxinus species).

Most of the gall is on the underside of the main vein, where it forms a narrow green pouch.

[1][2] It is found on Fraxinus angustifolia & subsp., F. excelsior, F. ornus and F.

[3] The larvae of Clinodiplosis botularia are reddish-yellow, grow faster and outcompete the gall maker, which perish.
