flies

Flies / Diptera is an order that follows the class of insects of the phylum Arthropods. It is a large order of insect species. It has two wings on its middle chest and two stabilizing pins located at the back of the insect's chest. The presence of a single pair of wings is what distinguishes it from other insects

Different types of flies produce two types of larvae, all without legs, the first type is characterized by the presence of a plate or head capsule, and chewing mouth parts, while the second type, known as the larva, is characterized by its worm-like shape, and has a mouth equipped with hooks, while the mouth parts are reduced, and the adult fly It is distinguished by the fact that its middle chest is larger than both the front chest and the back chest in terms of size, and that the wrist of its legs is made up of five sections. As for the antennae, they differ from one type to another, where there are threadlike antennae, and the other sutures, and spinal antennae

The larvae of flies live in places that protect them from the danger of drought; Therefore, they abound in aquatic and semi-aquatic environments, moist soil, animal dung, in addition to plant and animal tissues, and the larvae of most types of flies feed on the organic materials of living organisms after their death, or parasitize on animals, especially vertebrates, arthropods, and mollusks

Few of them also feed on plants, and the larvae of all types of flies are legless, but the larvae of more primitive species, such as the larvae of flies belonging to the nematodes of the horn, have a developed head plate or capsule and mouthparts attached to a jaw, while the more developed species such as shorthorns produce Druzes are worm-like larvae that possess a pair of hooks for feeding, have no head capsule or mouthparts, and, if present, are often shortened

The adult fly is adapted to live in a wide range of habitats, and differs in its shape and lifestyle from one species to another, and this is evidenced by the diversity of the mouth parts of the flies, as the mouth of the types of flies that feed on honey, nectar, or secretions of dead and living plants and animals contains a suitable hose. For sucking and licking, the proboscis of deer flies that parasitize animals and humans are modified to be suitable for puncturing, cutting, and sucking the blood of the host host

Flies belong to the order of two-winged insects, and are distinguished by their use of only one pair of wings to fly, while the other pair is reduced to form two balancing pins that are used to maintain balance. Flies are spread all over the world, including subarctic regions and high mountains, and it is worth noting that the word The fly is used in entomology to refer to flies that have several characteristics. Such as: the compound eyes are large in size, and the antennas that differ in their shape from one type to another, like the mouth parts that transform into several types depending on the type of fly and the way it is fed; Where there are sucking mouthparts, sucking piercings, squishy cutters, or squishies
