22 facts about Housefly

Housefly
11.The female lays about one hundred eggs in a single batch.
The laying process can take several days, and over a lifetime, a female housefly can lay up to 2,000 eggs, although this number does not usually exceed 500.
12.Housefly eggs are about 2.5 mm in diameter.
They are most commonly laid in pig feces, where up to 15,000 larvae may hatch in one kilogram of a substrate. After 24 hours, the larvae hatch from the eggs and feed on the liquid fraction of the substrate. The quality and freshness of the substrate affect the growth rate of these insects.
13.Fly larvae are called maggots.
They are white, legless organisms that feed on organic material at their hatching site. After hatching, they avoid light. Larval development takes two weeks under optimal conditions to 30 days or more in a cooler environment.
14.The housefly larva goes through three stages of development.
At the end of the third stage, the larvae crawl to a dry, cool place and develop into pupae. The pupa has a cylindrical shape with rounded ends. It reaches a length of about 1.2 mm and consists of the last stripped skin of the larva. At first, it is yellowish, darkens with time, and becomes practically black with red and brown tint.
15.The metamorphosis of the pupa at 35 °C lasts from two to six days.
At 14 °C, metamorphosis may take more than twenty days. After hatching from the cocoon, the fly stops growing and reaches its maximum size. A housefly pupa weighs between 8 and 20 milligrams.
16.The size of a fly is not an indication of its age.
Whether a fly is large or small only indicates whether the insect fed adequately during the larval stage.
17.Adult houseflies live from two weeks to one month.
Individuals reared under laboratory conditions live even longer. Males reach sexual maturity 16 hours after hatching and females after 24 hours.
18.When conditions are optimal, the life cycle of a fly may be completed within seven to ten days after hatching.
Under less favorable conditions, it can take up to two months.
19.They are the prey of many animals.
They constitute a significant meal for birds, reptiles, amphibians, spiders, and other insects. In turn, eggs, larvae, and pupae are usually threatened by parasitism.

Histeridae beetles feed on fly larvae and some mites larvae such as  Macrocheles muscaedomesticae feed on fly eggs. A single larva is capable of eating 20 of these per day.
20.Flies are a transmission vector for over 100 pathogens.
Because they can travel up to several miles from their breeding sites, they spread various diseases and parasites found on fly body hairs, mouthparts, vomit, and feces. The pathogens spread by flies cause typhoid fever, cholera, salmonellosis, dysentery, tuberculosis, anthrax, and ocular inflammation.
