Midge (family Chironomidae), also called chironomid, nonbiting midge, or gnat, any of a group of tiny two-winged flies (order Diptera) that superficially resemble mosquitoes. Although they resemble mosquitoes, midges are harmless, with small mouthparts that are not elongated into a piercing structure for blood feeding. They do not have scales on wings or body, and the pattern of wing veins differs from that of mosquitoes. The male antennae are feathery.
Midge was re-introduced in 1988 as part of the play line, though two vintage reproduction dolls were made specifically for collectors in 1993 and 1998. The dolls sold in this time period usually had red hair, often with freckles, and her eye color was usually blue.idge was re-introduced in 1988 as part of the play line, though two vintage reproduction dolls were made specifically for collectors in 1993 and 1998.
