Drosophila melanogaster is a species of Diptera, or the order of flies, in the family Drosophilidae. This species is one of the most commonly used model organisms in biology, including studies in genetics, physiology, microbial pathogenesis and life history evolution because they are easy to take care of, breed quickly and lay many eggs.
