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 |
