A genus of small flies that are extensively used as test animals to study genetics, cell biology and developmental biology. The most well-known species used is Drosophila melanogaster, the common fruit fly.
Drosophila is a genus of small flies whose members are often called small fruit flies, or more appropriately vinegar flies, wine flies, pomace flies, grape flies, and picked fruit-flies. A second insect family, the Tephritidae are also called fruit flies; they feed on unripe or ripe fruit. One species in particular, Drosophila melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology.
