Drosophila elegans is a flower-feeding species of fruit flies, belonging to the family Drosophilidae. It is found in Taiwan and the Philippines in Asia. It belongs to the Drosophila melanogaster species group where it forms it own subgroup. There are two morphs (brown and black) of the species. The difference is due to the percentages of 7- and 9-pentacosene on the cuticle. As a lab model species, it requires banana-opuntia-protein food. Its genome has been sequenced in 2011.
