    • n Cecidomyia A genus of nemocerous Diptera, or small two-winged flies, typical of the family Cecidomyiidæ, containing such as the Hessian-fly, C. destructor, noted for the ravages of its larvæ upon crops. C. tritici is the wheat-fly. The genus comprises a vast number of minute, slender-bodied midges, which are of special interest on account of their mode of life, the peculiar structure exhibited in the larvæ, and the economic importance attached to several species. In most cases the female lays her eggs in the stems, leaves, or buds of various plants, producing gall-like excrescences of various forms, inhabited by the larvæ. These are sub-cylindrical, legless grubs, mostly of a reddish or yellow color, and are furnished on the ventral side of the thoracic joints with a corneous plate, usually forked, called the breast-bone. Some species, however, do not produce galls, and among these the most familiar are the Hessian-fly and the clover-seed midge, C. leguminicola (Lintner), which latter infests the seeds of clover, causing great damage in the more northern parts of the United States. See also cut under fly.
