Behaviour
Adult blow flies feed on a variety of materials, but the larvae of most species are scavengers that live on carrion or dung. The adults lay their eggs on the carcasses of dead organisms, and the larvae (maggots) feed on the decaying flesh. The larvae of some species (e.g., Calliphora, Cochliomyia) also sometimes infest open wounds of living animals.
 Nuisance to people. The reproductive potential of fruit flies is enormous; when the surrounding is conducive, they are able to lay about 500 eggs
Rest on surfaces with their wings held over their back forming a roof-like structure
Female flesh flies give live birth after the eggs hatched inside of her abdomen, depositing maggots on a suitable breeding site.
Mouthpart fully adapted for sucking fluid and semifluid food. When not in used – the mouthpart is partially drawn into head capsule. Feed on: almost all food for human, rotting vegetable, carcasses, excreta and vomit - almost all organic food
Robust fly, prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night.
Crane flies do not bite or sting but can become a major pest to turf, pasture grass, golf courses, and field crops. This is because of their voracious larvae, which can leave grass yellow and thinning – and whole patches entirely bare.
Hatched larvae may cause damage to plant roots in large concentrations and attract more pests and may try to dig up the ground in order to feed on them.
Habitat
Blow flies like to inhabit on dumping area and decomposing organic matters.
Fruit flies are especially attracted to ripened fruits and vegetables in the kitchen. But they also will breed in drains, garbage disposals, empty bottles and cans, trash containers, mops and cleaning rags
Floor trap, plumbing drains and sewage systems
Relatively uncommon in houses or restaurants. They usually breed in excrement, decaying organic matter and animal flesh or meat
Normally sheltered indoors, avoiding direct sunlight
The larvae of horse fly develop in the mud along pond edges or stream banks, wetlands, or seepage areas. Some are aquatic and a few develop in relatively dry soil. Females lay batches of 25 to 1,000 eggs on water plant or wet sites
Larval habitats include all kinds of freshwater, semiaquatic environments
Life cycle
Complete life cycle takes about 2-3 weeks.
Complete life cycle from egg -> adult in a week
Complete life cycle takes about 10-15 days
Complete life cycle takes about 10-14 days
Complete life cycle takes about 7-10 days
They take about 1 year to complete the cycle
Eggs hatched into hungry larvae in 2 weeks time
