Diptera Is One Of The Major Insect Orders And Of Considerable Ecological And Human Importance. Flies Are Important Pollinators, Second Only To The Bees And Their Hymenopteran Relatives. Flies May Have Been Among The Evolutionarily Earliest Pollinators Responsible For Early Plant Pollination. Fruit Flies Are Used As Model Organisms In Research. Flies Are Often Abundant And Are Found In Almost All Terrestrial Habitats In The World Apart From Antarctica. They Include Many Familiar Insects Such As House Flies, Blow Flies, Mosquitoes, Gnats, Black Flies, Midges And Fruit Flies. More Than 150,000 Have Been Formally Described And The Actual Species Diversity Is Much Greater, With The Flies From Many Parts Of The World Yet To Be Studied Intensively.
