The fly is a terrestrial insect, with a great presence in the environment that belongs to the Insecta class and the Diptera order. The most common part of the Muscidae family and found in most regions of the world. Its scientific name is Musca domestic. The earliest known fossils of flies are amber from the Baltic, that is, from 35-40 million years ago. The insect lived 20 million years ago and presents four very well-defined wings (the actual flies only have two).
The Californians (beetles) are estimated to have appeared during the Tertiary, 20-30 million years ago. However, the oldest pupae that undoubtedly belong to the Californians, are remains found together with Australopithecus bones in South Africa, dating to 1-2 million years. Unlike beetles and other insects, adult flies are rarely kept. Consequently, they are not usually preserved in archaeological remains.
In contrast, pupae are very durable and are often found in archaeological excavations in many parts of the world. This helps to know the environmental conditions that prevailed during historical times.
Characteristics of Fly
The fly reaches 1cm. This species inhabits gardens, Rear, and open spaces. The fly is a species that is usually active during the day. Flies have eyes composed of several cells, which helps them to see in all directions. They also have small side-eyes, located on the top of the head called ocelli. These annoying flying insects have a viewing angle of almost 360 °, meaning that they see virtually everything around them, and not just head-on as we humans do.
The fly has a body divided into three zones: head, thorax, and abdomen. Although it is an insect that walks through the garbage, it is not so dirty, because when landing in any area, they rub their feet to remove all the dirt from them. This species has a liquid that causes it to expel any dirt by simply rubbing its legs. Flies have 15,000 taste buds spread over their paws.
The flies that itch are those that have the mouthpiece sucking Picador. These with their calorific sensors detect where the arteries or the veins are more superficial. When they have already completed this step, they make the cut with the scissors, blow their sorbet to clean it and with this same suck the blood. Generally, you do not feel the sting because the flies have an analgesic substance that they apply to him before pricking.
The hairs that own the flies serve to maintain the internal temperature of the body. Flies like all insects have tracheal breathing: small openings on the sides of the toráx called spiracles, where oxygen enters the tracheas, and then into the body. The size of the spiracles and the tracheas are one millimeter or less, depends on the proportion of the fly. You May Also Like To Read Roundworm.
The fly feeds on decomposed meat, feces, sugary matter, such as decomposed fruit and nectar. The fly vomits its food and then returns it to eat. They do not chew but absorb and regurgitate fluids. What we believe flies vomit is the liquid they use to dissolve the solids, and then digest them. This one is yellow.
Flies are used as biological control, as they parasitize various species of bedbugs. Another positive aspect of flies is that they serve as prey for other animals, such as small rodents and birds, making them an essential part of the food chain. Some of these insects are active pollinators, especially cruciferous plants and tails.
The fly has an endless number of enemies, including spiders, amphibians such as frogs and toads, reptiles such as chameleons, insectivorous birds such as robin, thrush or nightingale.
The life cycle of this animal passes through four morphological phases, which means that it is holometábolo: egg, Cresa or larva, pupa, and adult. The life expectancy of flies is up to 15 and 25 days. Some species of flies can complete all their cycles in a few days, and others in one or two months.
A fly can spawn up to 5 generations in 1 year. Over the next 24 hours, larvae begin to hatch and devour organic remains that are highly nutritious. At that time they have an average size of 3 to 9 millimeters in length, without legs, with a terminal mouth, and pale in color. You May Also Like To Read Chickenpox
After feeding, they become a pupa, which is brown or reddish, about eight millimeters in length. Once the metamorphosis occurs, the adult fly circularly breaks a part of the pupa. And it takes flight in the search of congeners to mate and to be able to conclude its life cycle.
Each female can lay about eight thousand white eggs, approximately 1.2 millimeters in length. Not all flies lay eggs. Some species are ovoviviparous, that is, eggs hatch inside the mother, which causes the offspring to come out in the form of larvae.
The fly has compound eyes, formed by a set of individual lenses. As the eyes of the fly do not have eyelids, to clean them the fly uses its previous extremities. The fly, although it may seem like an unpleasant animal, is very beneficial, allows the recycling of decomposing matter, is a good source of food for insectivorous animals, and participates in the pollination of plants.
On its legs, it has small adherent pillows that offer the possibility of walking on smooth surfaces like glass. Adult flies usually measure between 5 and 8 millimeters in length, and between 13 and 15 millimeters of wingspan. Females are generally larger than males and have greater separation of their two eyes.
In your body it carries bacteria, making it very dangerous for health. Each female can lay about eight thousand white eggs, approximately 1.2 millimeters in length. The biggest disadvantage is that flies feel attraction for decaying flesh and fecal matter, which are often a source of transmission of infectious diseases such as cholera, dysentery, and typhoid fever. Likewise, flies can transmit epizootics, and sleep sick.
Flies are insects of the order Diptera, the name is derived from the Greek δι- di- “two”, and πτερόν pteron “wing”. Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. This article has covered some basic facts about flies and how they relate to humans in terms of their biology (including reproduction) and behavior.
