22 facts about Housefly


Musca domestica

It is one of the most common insects on earth. It is found in almost every corner of the planet. The housefly is thought to have originated in areas of the Middle East in the early Cenozoic, which began 66 million years ago and continues to this day. Across the globe, the housefly has spread through migration and human colonization.
1.It is probably the most widespread insect in the world.
It is found in all populated parts of Europe, Asia, Africa, Australasia and the Americas, in the Arctic and in tropical equatorial forests, where it is widespread.
2.The house fly is a small insect, reaching a size of 6 to 7 mm.
The wingspan is 13 to 15 mm. The female fly is larger than the male.
3.Each leg ends in a pair of claws and pulvilli.
The pulvilli is an adhesive tab that allows the fly to move along walls using Van der Waals forces. This effect is based on the mutual attraction of electrons and nuclei in molecules, specifically between the permanent dipole and the induced dipole induced by the molecules that build the adhesions.
4.The thorax of a housefly is dark gray and covered with darker stripes.
The underside of the body is lighter than the top.
5.Flies have a liquid diet adapted mouthparts.
It is used to ingest liquids and the solid fraction previously dissolved with saliva.
6.The eyes of flies provide a 360° field of vision.
They are brownish-reddish in color, compound and consist of about four thousand ommatidia.
7.They are mainly carnivorous and feed on decaying organic matter.
Both adults and larvae can be found on decaying vegetables, fruits, meat, and plant secretions. Adults also feed on the nectar of flowers. Solid food is softened with saliva before being aspirated.
8.Houseflies play an important ecological role in the decomposition and processing of organic matter.
By feeding on feces and carrion, flies contribute to faster decomposition.
9.Flies flap their wings about 200 times per minute during flight.
Average housefly speed is about 8 kph.
10.Because of their ectothermic nature, they are most active in warm conditions.
The search for warmth explains why flies so eagerly seek shelter in human dwellings. 12 generations may hatch in temperate regions per year; in the tropics and subtropics, more than 20.
