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]
Like other members of the Drosophilidae, D. suzukii is small, approximately 2 to 3.5 millimetres (5 ⁄ 64 to 9 ⁄ 64 in) in length and 5 to 6.5 millimetres (13 ⁄ 64 to 1 ⁄ 4 in) in wingspan [3] and looks like its fruit and vinegar fly relatives. Its body is yellow to brown with darker bands on the abdomen and it has red eyes.
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.
An adult fruit fly is a strong flier that's been known to travel 30 miles in search of food and sites to lay eggs, giving it the ability to infest new areas quickly, according to the food and ...
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.
They include many familiar insects such as house flies, blow flies, mosquitoes, gnats, black flies, midges and fruit flies. More than 150,000 have been formally described and the actual species diversity is much greater, with the flies from many parts of the world yet to be studied intensively.
Some fruit flies have extensive mating rituals or territorial displays. Many are brightly colored and visually showy. Some fruit flies show Batesian mimicry, bearing the colors and markings of dangerous arthropods such as wasps or jumping spiders because it helps the fruit flies avoid predation, though the flies lack stingers.
