Midges comprise many kinds of very small two-winged flies. The term does not encapsulate a well-defined taxonomic group, but includes animals in several families of Nematoceran Diptera. The habits of midges vary greatly among the component families, which include:[1]
- Blephariceridae, net-winged midges
- Cecidomyiidae, gall midges
- Ceratopogonidae, biting midges (also known as no-see-ums or punkies in North America)
- including the Highland midge Culicoides impunctatus
- Chaoboridae, phantom midges
- Chironomidae, non-biting midges
- Deuterophlebiidae, mountain midges
- Dixidae, meniscus midges
- Scatopsidae, dung midges
- Thaumaleidae, solitary midges
While the Ceratopogonidae (biting midges) are serious biting pests, and can spread the livestock disease Blue Tongue, the other midge families are not. Most midges, apart from the gall midges (Cecidomyiidae), are aquatic during the larval stage. Some Cecidomyiidae (e.g., the sorghum midge) are important plant pests. The larvae of some Chironomidae contain haemoglobin and are sometimes referred to as bloodworms.[2]
