Larval Diptera feed in leaf-litter, in leaves, stems, roots, flower and seed heads of plants, moss, fungi, rotting wood, rotting fruit or other organic matter such as slime, flowing sap, and rotting cacti, carrion, dung, detritus in mammal bird or wasp nests, fine organic material including insect frass and micro-organisms.
On the other end of the spectrum, horse flies and deer flies use "blade-like" mouthparts to slash the skin before eating the spilling blood, which causes large, painful bites, Frye says.
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.
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.
Anastrepha is the most diverse genus in the American tropics and subtropics. Currently, it comprises more than 300 described species, including nine major pest species, such as the Mexican fruit fly (A. ludens), the South American fruit fly (A. fraterculus complex), the West Indian fruit fly (), the sapote fruit fly (A. serpentina), the Caribbean fruit fly (A. suspensa), the American guava ...
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]
For terms see Morphology of Diptera.Chloropidae are minute to small (1.0 to 4.0 mm), rarely medium-sized, flies (6.0 to 9.0 and 12 mm) They are either black, gray, yellow, or greenish and the mesonotum often has a pattern of three to five dark longitudinal stripes against a light-colored background.
Bibionidae (March flies) is a family of flies containing approximately 650–700 species worldwide.Adults are nectar feeders and emerge in numbers in spring. Because of the likelihood of adult flies being found in copula, they have earned colloquial names such as "love bugs" or "honeymoon flies".
