The rhinoceros beetle is an insect belonging tofamily of lamelliformes and to the type of arthropods. Its habitats are localized everywhere, except for taiga and tundra. Preference is given to forests with broad-leaved trees. You can meet him in the gardens, as well as in the territories with artificial plantings. The name of this insect very well approaches its appearance. Beetles really are very much like a real rhino. Like this animal, they have an outgrowth located on the front of the head - a horn. In addition, the body of the beetle is covered with a thick layer of chitinous "armor". A slow gait and the whole appearance of this insect makes it a miniature likeness of a large animal.
The rhinoceros beetle has a massive body, which inlength can be from twenty-five to forty centimeters. His legs are strong and thick. The front ones are designed to perform the digging function, and the rear ones, having small spikes and denticles, are for support. Male beetles have a three-toothed transverse elevation on the pronotum. The horn bent back is located on the head. In female individuals, only a small tubercle rises on the nose. The back of the beetle can have a different color, depending on the environment. It varies from reddish-brown to dark-brown color. The extremities and abdomen are much lighter. Their outer cover is yellowish-brown hairs. The chitinous shell of the insect has a shiny surface.
The rhinoceros beetle, which belongs to the class of insects,has similar structure to other representatives of this class. The limbs, and even the body itself consists of several segments - segments. Three pairs of legs, designed for walking, are located on the chest of the beetle. They consist of five segments. There are limbs at a fairly large distance from each other. At the same time, it seems that the beetle has spread its legs widely. The insect shows activity with the onset of twilight. The beetle flies fine. Without stopping, he is able to cover a distance of fifty kilometers.
The amazing property of an insect isthe fulfillment of its qualities of semiconductors by the iglane. They are manifested when exposed to ultraviolet rays. The rhinoceros beetle, the food of which remains uncertain until the end, according to one data uses plant juice or liquefied food. Other specialists are of the opinion that there is aphagia. That is, some scientists believe that the insect does not feed at all. During its existence, it uses the nutrients that the larva of the rhinoceros beetle has accumulated. Confirmation of the first version is the structure of the mouth of the insect. Its chewing surfaces are poorly developed and do not have teeth for grinding solid food. At the same time, the lower jaws are covered with brushes made of dense long hairs, which are supposed to facilitate the collection of plant juice. Confirmation of the second opinion is the state of the digestive organs. They are almost completely atrophied.
The rhinoceros beetle breathes atmospheric air,falling into his respiratory organs through spiracles, which are located on the abdomen and chest. The circulatory system of an insect is not closed. The beetle's heart is on the back. It is a tube divided into chambers having valve openings. The organs of beetle excretion are represented by the fat body and Malpighian vessels. In the management of the basic processes of functioning of the entire body of an insect, the central nervous system is involved. Well-developed sense organs, together with the horn, contribute to the successful orientation of the beetle in space. The insect is very strong. It is able to move cargo, the mass of which exceeds its own weight by a thousand times.
