Interesting facts about flies

Posted on May 8, 2022      207


Pesky insects like flies have an important place in nature. They serve as food for many birds, spiders, and other critters, and because they reproduce extremely quickly, their population is not declining. But some of them can also be dangerous, such as the famous tsetse fly, which is fierce in Africa. Fortunately, modern science has learned how to combat such plagues.

Facts about flies

  • Some of their species live only in the wild, while others long ago adapted to coexist with humans, and can no longer survive without humans.
  • Different flies feed on completely fresh foods, from plant sap to blood and excrement.
  • Many people have seen flies rubbing their legs against each other. They do it in order to clean dust and dirt from the pads of their feet, because their taste buds are located there. Flies sense flavor by touching it with their paws.
  • The larvae of these insects are very similar to small worms.
  • There are no hairless flies. All their species are covered with hairs, but thin, so visually they are not conspicuous.
  • Flies’ eyes comprise several thousand segments-fascicles.

  • Besides colors, flies also distinguish ultraviolet light.
  • They can sense odors at a distance of up to 500 meters. The olfactory organs are the antennae growing on the head.
  • In ancient Egypt, an honorary military award for bravery was a golden fly the size of a palm. It was awarded to especially distinguished warriors.
  • The stomach of flies is not adapted to digest solid food, so before eating, they wet it with their saliva.
  • The average housefly lives on average about 30 days. During this time, under favorable conditions, they lay up to 3,000 eggs.
  • Flies are carriers of dangerous diseases such as typhoid, anthrax, tuberculosis and more.
  • The most dangerous tsetse flies do not bite zebras, because in their eyesight, the striped skin of these ungulates looks like a disorderly flurry of black and white stripes. The zebras themselves are not tameable, but locals have long used partially striped hybrids between zebras and horses in agriculture, as they are much less often bitten by tsetse flies than conventional horses.
  • The Hessian fly, also called the “bread mosquito” because of its outward resemblance to mosquitoes, feeds on grain plants. In the Middle Ages, swarms of these insects repeatedly devastated fields no worse than locusts, causing famine in entire areas.
  • The real scourge of gardeners and farmers is the cabbage fly. It practically does not harm itself, but its larvae devour all cabbage.
  • The pincushion flies attack other tiny insects in flight, put them on their spiny paws and suck their insides.
  • Tollflies are also related to flies. They get their name because they lose interest in everything around them while they are feeding, and they are easy to swat.

  • Some species of flies are beneficial. For example, the tahina lays its eggs in the larvae of other insect pests.
  • In Iceland, New Zealand and Japan there are amazing species of flies, which are born and spend their entire lives near thermal springs at temperatures of +55-60 degrees.
  • In green flies, the female usually tries to eat the male after mating. To avoid this fate, the male usually brings some kind of food to the female before mating. But this does not always help him.
  • One of the most famous works of the children’s writer Korney Chukovsky, “The Fly and the Dumpling”, tells exactly about this insect.
  • The aforementioned tsetse fly is not poisonous, but it carries the most dangerous sleeping sickness. Because of it, tens of thousands of people and a huge number of livestock die each year in Africa.
  • In the United States, California, there are flies whose larvae hatch in lakes of crude oil.
  • The larvae of some species of these insects can parasitize in the bodies of a wide variety of living things, from earthworms to humans.
  • All flies lay eggs to reproduce. More precisely, all except one, which produces offspring by live birth.
  • One kilogram of pig manure contains enough nutrients to produce 15 thousand fly larvae.
  • Because of their modest size, the flies weigh very little. About 40 thousand flies will weigh near 1 kilogram.
  • In Ethiopia, scientists have reduced the population of the most dangerous tsetse flies. They breed the flies in special plants, sterilize the males, and destroy the females. The males are then released into the wild. The fact is that after fertilization, albeit false, the female does not let other males near her.
  • The most short-lived flies are mayflies. They live about a day.
  • An ordinary housefly can carry the dirt on its legs up to 20-25 km from the place where it picked it up.
