The eggs, which are about 0.5 mm long, hatch after 12–15 hours (at 25 ☌ or 77 ☏). Their life cycle is broken down into 4 stages: embryo, larva, pupa, adult.

Drosophila melanogaster is a holometabolous insect, so it undergoes a full metamorphosis. Females lay some 400 eggs (embryos), about five at a time, into rotting fruit or other suitable material such as decaying mushrooms and sap fluxes. Under crowded conditions, development time increases, while the emerging flies are smaller. Under ideal conditions, the development time at 25 ☌ (77 ☏) is 8.5 days, at 18 ☌ (64 ☏) it takes 19 days and at 12 ☌ (54 ☏) it takes over 50 days. Development times decrease at higher temperatures (11 days at 30 ☌ or 86 ☏) due to heat stress. The shortest development time (egg to adult), 7 days, is achieved at 28 ☌ (82 ☏). melanogaster varies with temperature, as with many ectothermic species. melanogaster lifespan is about 50 days from egg to death. Under optimal growth conditions at 25 ☌ (77 ☏), the D. Their eyes are sensitive to slight differences in light intensity and will instinctively fly away when a shadow or other movement is detected. Drosophila melanogaster flies can sense air currents with the hairs on their backs. Furthermore, males have a cluster of spiky hairs (claspers) surrounding the reproducing parts used to attach to the female during mating.

Males are easily distinguished from females based on colour differences, with a distinct black patch at the abdomen, less noticeable in recently emerged flies, and the sexcombs (a row of dark bristles on the tarsus of the first leg). They exhibit sexual dimorphism females are about 2.5 mm (0.10 in) long males are slightly smaller with darker backs. The brick-red color of the eyes of the wild type fly are due to two pigments: xanthommatin, which is brown and is derived from tryptophan, and drosopterins, which are red and are derived from guanosine triphosphate. Wild type fruit flies are yellow-brown, with brick-red eyes and transverse black rings across the abdomen. This can cause confusion, especially in the Mediterranean, Australia, and South Africa, where the Mediterranean fruit fly Ceratitis capitata is an economic pest. įlies belonging to the family Tephritidae are also called 'fruit flies'. melanogaster is a common pest in homes, restaurants, and other places where food is served. Its geographic range includes all continents, including islands. It was originally an African species, with all non-African lineages having a common origin. melanogaster is typically used in research owing to its rapid life cycle, relatively simple genetics with only four pairs of chromosomes, and large number of offspring per generation.

As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the animal. melanogaster continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. Woodworth's 1901 proposal of the use of this species as a model organism, D. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the ' vinegar fly' or ' pomace fly'. Drosophila melanogaster is a species of fly (the taxonomic order Diptera) in the family Drosophilidae.
