The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. [1] Another distantly related family of flies, Tephritidae , are true fruit flies because they are frugivorous, and include apple maggot flies and many pests.
Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/ [1] [2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.
Unlike humans, the sex and physical appearance of fruit flies is not influenced by hormones. [16] The appearance and sex of fruit flies is determined only by genetic information. [16] Female fruit flies are substantially larger than male fruit flies, with females having bodies that are up to 30% larger than an adult male. [17] [18]

Fruit flies are also drawn to things such as drains, garbage disposals, empty bottles and cans, trash bags, cleaning rags and mops. Essentially, they are drawn to food waste and moist environments ...

Oxygen in the tracheal tube first dissolves in the liquid of the tracheole and then diffuses across the cell membrane into the cytoplasm of an adjacent cell. At the same time, carbon dioxide, produced as a waste product of cellular respiration, diffuses out of the cell and, eventually, out of the body through the tracheal system.
The flies of these species have switched host plants to prickly pear cacti on these islands, and genetic differences have also been isolated in these flies. After comparing the genotypes of these species on the Catalina islands to other flies that use prickly pear cacti as their hosts, haplotype relationships among D. mettleri and D. mojavensis ...
