The biggest fly in the world
Content
The fly is one of the most annoying insects attacking a person’s home during the warm season. There are over seven tens of thousands of different species of fliesamong which there are both harmless and biting creatures. There are those that carry infections. Pretty sticky dung fliesthe most common are room. Adapting to a living organism and laying its own parasitic eggs there can be a fly larva, with the result that the larvae begin to develop right in the stomach and intestines,later gnawing his moves to other organs. In its own way, the biggest fly is also amazing. On the most interesting and large copies and will be discussed in this article.
Gauromydas heros
The largest fly in the world Gauromydas heros from the family Mydidae is an inhabitant of the forests of South America. It is a very large insect whose body length reaches 6 cm. It has this creature and the largest wingspan (up to 10-12 cm). The main body color is black (a photo of a big fly can be seen below).
The biology of this large insect is not yet fully understood, since imago is quite rare. It is known that only males feed on nectar, the female individuals are stocked with nutrients, being in the larval stage. Larvae the largest member of the fly family lives in the ant burrows of Atta Fabricius and pupates in the soil.
Interesting!
When meeting a person, a big black fly can leave a mark on the body in the form of a large bruise. About how dangerous this "giant" has not yet been established.
Hippobosca equina
Hippobosca equina flies or horse leech can be attributed to insect giants.A representative of this species has a large size (body length can be 6-8.5 cm), wide chest and fairly strong wings. On the brilliant brown color of the body is well highlighted yellow pattern from the side of the chest. The oral apparatus is represented by large powerful jaws identical to sharp knives.
Wings have young individuals who lose them after attacking the victim. Horses and cattle usually serve as the latter. Insect clings to the tail, belly or the hips of the animal. Fly bite causes skin irritation that causes great discomfort. Moreover, only females bite to feast on the blood of mammals during the mating season. The rest of the time, the huge fly is harmless, as it feeds on nectar and pollen of plants.
Ktyr
Representatives of this species can be found everywhere, with the exception of the territory of Antarctica. A fly ktyr is a predator-exterminator of various insects (flies, beetles, wasps, butterflies, grasshoppers, beetles) than sometimes provides a great service to man.
Differs in large size (5-8 cm), strong body, strong spiked limbs, hard proboscis.A characteristic feature of the structure of the imago is a large mid-chest and elongated abdomen. The predator has a black color, sometimes there are species with brown, reddish or red sclerites. The whole body of the individual is covered with gray pollen, there are also specimens with a pattern of light stripes or spots. On the large head are the facet structure of the eye, three simple ocelli and short antennae.
On a note!
Caught victim ktyr destroys poison. With the help of a proboscis, the predator wounds its prey, and from the salivary glands it throws out a potent poison, which consists of substances splitting the entrails of the insect.
Bulldog fly
Another unpleasant insect is the Horsefly fly, referred to as the bulldog fly. In Russia, it is known as a gadfly.
It is not only the size of insects that are impressive (the length of their body can reach 3-4 cm), but also their rather powerful shell. The bite of the gadfly is unpleasant and rather painful. Most often, cattle are the victims of a bloodsucker’s attack, and a person may also suffer. Thanks to the powerful mandibles of the jaw, the flies exert strong pressure on the skin, cutting it like a knife.
Very often these flies are going to swarm and feed on together, so if such a swarm attacks a hulking animal, then the chances of driving the bloodsuckers away are almost negligible.
On a note!
"Vampire" features appear in females of gadflies exclusively during mating games, yet the remaining time they feed on nectar and pollen of flowers.
Glutton bovine Tabanus bovinus Linnaeus
Another giant fly whose body length is 19-24 mm. In the upper part, the insect's abdomen has a dark gray color, it is yellow-brown with a brown stripe from below. First two segments of antennae brown, others black. In males, unlike females, eyes are closed.
Females suck the blood of cows, horses and other large mammals. A person is attacked very rarely. Food for males is nectar of plants. The larvae develop in moist soil.
Insects are distributed almost throughout Europe (except for the northern regions), the Caucasus, and Western Siberia.
Big gray horsefly Tabanus autumnalis Linnaeus
Large well-known fly, whose body length reaches 16-23 mm. Quite often, such gadflies are mistaken for gadflies, although the latter are members of the Oestroidea superfamily.The insect has a dark gray color, the abdomen is black with a well-recognized pattern.
Females suck the blood of mammals, and they are able to attack humans. Before you sit down on their victim, they circle around for a long time. The vegetarian lifestyle is a large fly male, feeding exclusively on floral nectar. Insect is a carrier of very dangerous infections, such as anthrax.
You can meet such a fly in Europe, North Africa, Western Siberia, Asia, the Caucasus and Kazakhstan.
