Flies belong to the order Diptera, which gets its name from the Greek words di-'two' and pteron 'wing'. Although the name flies has been given to a variety of insects, it belongs specifically to the Diptera class. There are several types of flies like a house fly, fruit fly, horse-fly bee fly, drain fly, tsetse fly, lantern fly, may fly, scorpion fly, sand fly, yellow fly, and more.

We try to keep flies away with the help of fly repellent, fly paper, and other such deterrents as they spread numerous illnesses like E.coli and Salmonella. They often vomit or excrete after landing on our edibles, breaking down the food particles into smaller pieces, and proceed to eat this poop or vomit. Thus, spreading various germs and illnesses. Many people make fly traps with the help of jars, vinegar, and water.

Interestingly, fly bites are more common than you think. While some bites like the female black fly bite feeding on blood and are not particularly painful, the deer fly bite is painful and causes welts or bumps, giving you rabbit fever. A fly's predators are birds and other bigger insects.

Where do flies live?

Flies are terrestrial beings and can be found in many places. For example, house flies can be found in houses, in ceilings, walls, floor, plants, garbage cans, and in many more places, while fruit flies prefer places closer to food like kitchens, restaurants, and more places as such.

What is a fly's habitat?

Flies can live in almost any form of environment or organic matter. In lakes, birdbaths, marshes, wetlands, swamps, puddles, rivers, and even in brackish water, the larvae of aquatic species of flies can be found. Some larvae can be seen burrowing into bottom sediment while others live in the branches, roots, and leaves of plants. Non-aquatic flies can be found in soil, algae, herbs, trash, barks, dead bodies, houses, and kitchens. Flies prefer a warm and moist climate as it helps them breed.

Who do flies live with?

How long do flies live?

Horse and deer flies have a two to three-year lifespan but for common house flies and fruit flies, it is about 30-60 days. House flies complete their life cycle in about 30 days out of which they spend 25 days as an adult. Fruit flies stay in the larvae and pupae stage for about a week or two before becoming adults, in which stay they live for about 40-50 days. Most adult flies cannot survive winter but their larvae or pupae can. If a fly does survive winter, it is due to hibernation.

How do they reproduce?

Flies go through complete metamorphosis, whereby they undergo four stages i.e. egg or embryo, larva, pupa, and adult.

The release of tempting chemical odors or pheromones by female flies signals that they are ready to mate. Complex mating exercises exist in some species. For example, in the case of fruit flies, to successfully seduce the female fly, the male follows a set of steps. Even after the female issuing pheromones, he has to assure her that he is the best suitor. He starts by tapping the female on the stomach with his leg. This is followed by him strutting about with the vibration of his wings, 'singing' to her. If these steps are not completed in the correct sequence then the male fly is doomed.

Flies usually lay their eggs in huge numbers. They lay eggs in dozens and hundreds, and wet places like vegetables, fruits, carrion, fungi, manure, and inside their host in case of parasitic species. In her lifetime, a single housefly the Musca domestica can lay 600 eggs and more with almost 10 or more generations within one single breeding season. Eggs hatch about 12 hours to a week later in humid weather on the basis of the species. In some cases, live maggots are born which then feed on garbage and carcasses.

What is their conservation status?

While some flies like common house flies or fruit flies are found in abundance and have no conservation issues, there are some species of fly that are threatened or rare. Some like bog hoverfly or Clubbed General Soldier fly are becoming rare due to their habitat loss.

Flies taste food with their feet. This is due to the presence of taste receptors or chemonsensilla on their lower legs and feet. When a fly lands on a tasty meal, which can range from animal feces to your lunch, it will sometimes walk around to give its next meal a taste before consuming it.
