Fly is a type of insect that comes from the suborder of Cyclorrapha ordoDiptera. The morphology of flies is distinguished from the Nematocera subordo mosquitoes based on antenna size, short-acting flies, while long-anticipated mosquitoes. Flies generally have a pair of original wings as well as a pair of small wings that are used to maintain stability while flying. Flies often live among humans and some species can cause serious illness. The fly is called a very serious disease spreader because every fly perches somewhere, about 125,000 germs that fall into place.
Flies rely heavily on vision to survive. Flexible eye flies consist of thousands of lenses and are very sensitive to movement. Some types of flies have accurate three-dimensional vision. Several other types of flies, such as Ormia ochracea, have very sophisticated hearing organs.
