- insects with wings, or insects whose ancestors had wings
This large order has many different members living in various habitats. There are many feeding habits of the adults such as chewing, sponging, biting, cutting, piercing and sucking. The Diptera have complete metamorphosis (egg, larva, pupa, and adult). Diptera literally means two wings, which is true for most species, but some flies are completely wingless. Most larvae are found in wet places. Common in our area are house flies, Musca domestica. The larvae are maggots that feed on decaying animal or plant material, and the adults have sponge-like mouthparts for sucking up liquids. House flies spread germs which they often carry on their feet. Black flies (Family Simulidae) are important pests of wild animals and humans. They are capable of biting into the skin of their host and sucking up the blood. Black fly larvae live at the bottom of streams and small rivers, where there is cool unpolluted water; and they feed on small organisms suspended in the running water. Mosquitoes (Family culicidae) are common biting flies in northwestern Ontario. In warmer climates some species spread a variety of human diseases including malaria.
