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.
Gall-inducing insects are usually species-specific and sometimes tissue-specific on the plants they gall. Gall-inducing insects include gall wasps, gall midges, gall flies, leaf-miner flies, aphids, scale insects, psyllids, thrips, gall moths, and weevils. [36] Many gall insects remain to be described. Estimates range up to more than 210,000 ...

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.
The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
Galls induced by insects can be viewed as an extended phenotype of the inducing insect, and gall-inducing insects specialize on their host plants, often to a greater extent than insects that feed on the same plant without creating galls. [2] The gall's form or type depends on what organism is attacking the plant and where the plant is being ...
Galls. Melaphis rhois is an aphid species first identified by Asa Fitch in 1866. [1] Known as the staghorn sumac aphid, it is the only species in the genus Melaphis. [2] It is a type of woolly aphid and one of the few aphids that induce the formation of galls.
Rhopalomyia solidaginis, the goldenrod bunch gall, is a species of gall midges, insects in the family Cecidomyiidae. The galls of this species have the following host species of goldenrods: Solidago altissima , Solidago canadensis , and Solidago rugosa .
