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]
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.
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.
Larvae eat and burrow into the fruit that their mother laid them on. While grapefruits and oranges are preferred, other citrus fruits, pears, apples, and peach are also common hosts and thus food sources. [4] Like other fruit flies, A. ludens need to consume a mixture of amino acids, minerals, carbohydrates, water, and vitamins in order to ...
The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea , by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in ...
[13] [20] D. silvestris and other recently evolved planitibia species emit less complicated and higher frequency courtship songs compared to this subgroup's more ancestral flies. [21] D. heteroneura, another member of the plantibia subgroup, is a close relative of D. silvestris. Both of these fly species are native to Hawaii, and genetic ...
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking flight. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. [1]
Adult flies are found mostly on mammal excrement, including that of humans (less often on other rotting organic matter), where eggs are laid and larvae develop, and on nearby vegetation, carrion, fermenting tree sap, and shrubs and herbs. Many Sepsidae apparently play an important biological role as decomposers of mammal and other animal excrement.
