Cecidiomyiidae is the correct name for the insects known as the gall midge. They are flies (Order Diptera). As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls.

These are very fragile small insects usually only 2-3mm. in length and many are less than 1 mm long. They are characterised by hairy wings, unusual in the Order Diptera, and have long antennae. Worldwide there are 3000+ species but since 1,100 are from from well studied North America it is clear this is an underestimate. Many are economically significant especially the important insect pest of wheat, the Hessian fly , the galls causing severe damage to the crop. Other important pests include the lentil flower midge (Contarinia lentis), the lucerne flower midge (C. medicaginis) and the alfalfa sprout midge (Dasineura ignorata) on the Leguminosae ; the Swede midge (Contarinia nasturtii) and the brassica pod midge (Dasineura brassicae) on the Cruciferae; the pear midge (Contarinia pyrivora) and the raspberry cane midge (Resseliella theobaldi) on fruit crops. Antennae (singular antenna), are the paired appendages connecting to the first (and in crustaceans also to the second) segment of the head of the members of all subphyla of the arthropods except Chelicerata. ...

Curiously a large number of species are natural enemies of other crop pests.The larvae of these species are of are predaceous, and some are even reported as parasitoids. The most common prey are aphids and spider mites, followed by scale insects , then other small prey such as whiteflies and thrips and many eat the eggs of other insects or mites.Because the tiny larva are incapable of moving considerable distances, there usually has to be a substantial population of prey present before the adults will lay eggs and Cecidiomyiidae are most frequently be seen during pest outbreaks. One species Aphidoletes aphidimyza is an important component of biological control programs for greenhouse crops and is widely sold in the United States of America.

Cecidomyiidae are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. Even stranger in some species the daughter larvae produced within a mother larva consume the mother and in others the reproduction occurs in the egg or pupa. Paedogenesis is the act of reproduction by an organism that has not achieved physical maturity. ...
