Origins

Flies are insects of the Diptera order (derived from the Greek term di=two and pteron=wing), possesing only one pair of wings on the median thorax, a pair of sheaths. The housefly is one of the most popular animals. The Diptera order is a general order, including an estimated number of over 240,000 different varieties of insect species, although only about half of them have been studied and described (about 120,000 species) according to the authors estimate.

The Diptera order is one of the most important insect orders, some of these insects are predatory flies and mosquitoes, which are extremely important because of their role in the transmission of diseases like malaria and yellow fever.

Food Fly

Most feed on organic matter, even on the one undergoing decomposition. The fly will sit on anything and will basically eat anything.

Features Fly

Flies have a length of 5-10 mm; the anterior part of the body is black, crossed with four stripes on the back; the posterior part of the body is gray on top and yellow on the underside; the whole body is covered with hairs; the head has two compound eyes (facetted eyes) big and red; houseflies have only one pair of wings for flying, the second serves to stabilize the flight.

The fly is a typical upsetting agent and also a hygienic pest. Flies bother people, sitting and moving around on various parts of their bodies, flying erratically around the room and buzzing. By laying eggs and due to the larval feeding stage, they can contaminate food. Because they are disease carriers , they become a threat to hygiene. There is evidence that houseflies can transmit the Helicobacter pylori bacteria, which can cause ulcer in humans. This implies that the flies are carriers of other diseases too, although her role as transmitter of diseases is often overestimated.

To prevent the presence of flies, biodegradable garbage has to be discarded as soon as possible and regularly. Cat litter trays must always be clean. Foods that spoil should not be left outside and uncovered. The potential hatching places, such as manure and compost heaps, must be placed away from the house. To prevent flies entering the house you can install nets on windows and balcony doors.

Flies that will appear randomly can be killed with the classic flyswatter. Other methods that are combating flies are flypaper, fly nets, insect sprays and UV lamps. In restaurants, hotels and food companies it is recommended to use UV lamps, for aesthetic reasons.

Reproduction Fly

Among the most popular flies are the blue flies and meat flies. The female lays her eggs in manure, compost, rotting food (biodegradable garbage) and manure mixed with straws. After the embryonic development of about 15-25 hours, the larvae hatch, which have no head or legs.

By waving their body, they can easily move in the food substrate, without needing any help. They feed on substances found in the rotting matter. During this time they grow and shed twice before moving to the nymph stage. In this stage they are fusiform. The duration of metamorphosis performed in the nymph stage depends on temperature and is from 3 to 8 days.

On exiting, the fly will move the casing away by using a bladder, which comes out in an arc form, located on the head. Adult flies are three days after hatching ready for reproduction. Flies fly with great precision and agility. Their flight speed is 2m/s (7,2km/h), beating their wings 200 times per second.

Did you know that:

The fly lives anywhere where the man lives, where there is food and waste.

There is species of fly, Cephenomia, whose flight exceeds the speed of sund, reaching 1,3 km/h?

The flies larvae have been used to treat souldiers wounds in wars.
