Scientific name: Diptera (order)
Identification: True flies include flies, gnats, mosquitos, midges, and no-see-ums. In their aquatic larval stage, true flies are soft-bodied and barrel-shaped. They generally range in color from red to orange to tan, and they are segmented. In the adult stage, these flies have one set of membranous front wings, since their hind wings have been reduced to small structures used for balance.
Habitat: True flies prefer slow moving or still water to lay their eggs in. Some diptera are able to survive in oxygen-poor conditions, since they utilize hemoglobin as a respiratory pigment.
Overview: True flies feed on organic matter or decaying materials, and they are considered to be a nuisance by many. They can be vectors of disease, and they can also disrupt agricultural crop yields.
