Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls . Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long.
The Cecidomyiinae, commonly known as gall midges or gall gnats, is the largest subfamily in Cecidomyiidae with over 600 genera and more than 5000 described species. [1] Larvae of the other ( basal ) cecidomyiid subfamilies feed on fungi; whereas this subfamily is best known for its members that induce galls on plants.
Creosote gall midges are a species of gall-inducing flies in the Asphondylia auripila group (Diptera: Cecidomyiidae). This group consists of 15 closely related species of flies which inhabit creosote bush (Zygophyllaceae: Larrea tridentata ) sensu lato . [ 1 ]

Orseolia oryzae, also called the Asian rice gall midge, is a species of small fly in the family Cecidomyiidae.It is a major insect pest of rice. [2] [3] [4] The damage to the crop is done by the larvae which form galls commonly known as "silver shoots" or "onion shoots".

Asphondylia floccosa, the woolly stem gall midge, is a species of gall midges in the family Cecidomyiidae. [1] The larvae induce galls on Atriplex polycarpa. [1] They don't feed on the gall itself, but rather fungus that grows within the gall. Each gall can contain anywhere from one to fifteen chambers. [2]
