A spring friend is a beetle in May. How many legs does the beetle have and what are they used for?
May beetles in everyone are associated with the arrivalspring. It's no wonder, after all, these insects wake up after their hibernation only during the dissolution of oak buds and leaves on the birch (equivalent to establishing a constant warm weather).
Who is he, the May bug?
The skeleton is chitinous, so so strong. The size of the insect varies from 2 to 3 cm, but can reach 4 cm. The mechanism of dimorphism of the color of these beetles is interesting (that is, related individuals can be strongly discerned by the color of the calf). The color is often changed depending on how many legs the May beetle has. With red-and-red legs, the beetles have a red corpuscle, and with a graphite a black body. Coloring also affects the habitat. Black likes darkened forests, red prefer open areas.
The structure of the beetle's body is divided into segments. It consists of the head, abdominal and thoracic parts. The shell is covered with scales, which in appearance look very much like hairs. The head consists of seven plates, ends in the form of a mace.
Precisely answer the question of how many legs the beetle has,not difficult. His legs are fixed in various parts of the chest. Each limb is activated only when it becomes necessary to use it. So, how many legs does a beetle have? Three pairs, and each of them is used strictly for the purpose. For example, in front strong paws, a May bug digs a hole in order to lay eggs, and the rear beetles clings to a tree or foliage. The beetle has wings and elytra, they are rather heavy, which makes it externally slow and clumsy. The system of sense organs is well developed. For the sense of smell, the antennae respond ("sniffing" food from a kilometer distance). The organs of vision are the eyes located on the sides of the head (a survey of almost 360 degrees).
Transformation of the May beetle
May bug in the process of its development isseveral stages: an egg, a larva and a pupa. They form, and then strengthen the shell, wings, paws. Pupa is very much like an adult beetle, but it does not yet have a nervous system and wings. an amazing fact: according to scientists, wings simply can not physically lift the body of a beetle into the air, but this does not prevent it from flying. The female lays eggs in the spring, and full-bodied insects only appear in April-May of the following year. The life span of these insects is four to five years.
Now the reader knows how many legs the beetle has. For what they are used by insects, and how they affect the environment of its habitat.
