Insects of Cedar Creek

Order DIPTERA

Family CECIDOMYIIDAE

(Gall Midges)

(Table of Species)

The Gall Midges (1059 NA spp) is a large family of small, slender, fragile flies most of which attack a variety of plants and form characteristic galls. The state of New York (Felt in Leonard, 1923) reports 765 spp, and it is likely that a specialist could find at least 500 species in every state in the Union.  Specimens are commonly taken in old field sweeps. Some have been saved, but no attempt has been made to identify them.

The Gall Midges of Cedar Creek await some enthusiastic collector. I can mention but a few here. Rhabdophaga spp form characteristic cone galls on species of Salix and Rosa. Asteromyia spp form blotch galls on a variety of Asteraceae, and xx forms 'broom galls' on the tops of Solidago gigantea.
