Gall midge larvae, and many adults, are orange or yellow in color due to carotenoids. [10] Cecidomyiidae are among the very few animals which can synthesize carotenoids, but its unknown to what degree de novo biosynthesis of carotenoids accounts for their characteristic color as opposed to dietary sequestration or endosymbionts.

Females deposit 100-250 tiny (1 ⁄ 64 inch [0.40 mm]) shiny orange eggs singly or in small groups among aphid colonies that hatch in 2–3 days.After 3–7 days the larvae drop to the ground and burrow 3 ⁄ 4 to 1 + 1 ⁄ 2 inches (1.9 to 3.8 cm) inches into the soil to pupate.
A midge is any small fly, including species in several families of non-mosquito nematoceran Diptera. Midges are found (seasonally or otherwise) on practically every land area outside permanently arid deserts and the frigid zones.
During the spring and summer, males create mating swarms which people can find quite a nuisance, though adults do not bite or feed. Females lay egg masses in water where the egg mass will grow and sink to the bottom. The larvae stay at the bottom in silken tubes. [4] The larvae feed on organic material such as organic debris and algae.
Polytene chromosomes were originally observed in the larval salivary glands of Chironomus midges by Balbiani in 1881. They form through repeated rounds of DNA replication without cell division, resulting in characteristic light and dark banding patterns which can be used to identify inversions and deletions which allow species identification.
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". The rice plant is stunted and the seed heads fail to develop.

Chaoborus is a genus of midges in the family Chaoboridae. The larvae are known as glassworms because they are transparent. They can be found commonly in lakes all over the world and can be up to 2 cm (0.8 in). The adults are sometimes called phantom midges or lake flies. [1]
