beetles - insects belonging to the order Coleoptera.I got this unit its name from the hard chitin elytra, which serve as the back cover of membranous wings folded on the abdomen.Sometimes there are such kinds of beetles, which do not have rear wings, but chitin tegmen these insects are present necessarily.
In Russia, home to many different bugs.Great damage to agriculture does chafer.Not himself, and his voracious larvae.Not so long ago, in the 60 years of the last century, it was imported into Russia Colorado potato beetle, which has now become a real scourge growers.He is accustomed to the warm climate, adapted to our winters, hiding deep in the ground.And in the case of lack of his usual food - potatoes - this prozhora great eats quinoa, tomatoes, eggplant and other plants, like leaves, and fruit.
And another "alien" gives people a lot of problems.This home cockroach.This beetle has many subspecies that have chosen warm human dwellings, eating leftovers.
largest beetles of Russia - is a relic long-horned beetles or longhorn giants.Their size reaches 11 cm. Of their habitat is the Far East and South Primorye.To date, the number of representatives of this species decreased significantly, the beetle has become quite rare, so was entered into the Red Book.
And the biggest beetle in Europe - stag.We call it even stag beetle.They are in our country can be found.Surely every once in my childhood I caught and saw this amazing insect.
But not everyone knows that his "horns" - this is not the horns.The most amazing thing is that it is nothing like a modified upper jaw!With their help, stag beetles grab prey, fight with rivals because of females and defend against enemies.
The largest beetles found planets titan beetle and Hercules Beetle.Habitat - South America, its tropical forests.They reach 18 centimeters in length!
And if the first place in terms of these two beetles are forced to divide among themselves, so beautiful among them, undoubtedly, is the winner of the Hercules Beetle.Bright black long serrated horns, green spotted elytra - sight for sore eyes!
However, samochki this kind of almost half the length of the males, and they do not have horns.Taurus female black, covered with brown hairs, elytra and her lumpy.
But despite the fact that the beauty of their "spouses" samochki much inferior to males, as expected, bravely enter the battle with rivals for the possession of vending individuals.Hercules Beetle fighting for "the lady of his heart," using natural weapons - their "horns."They are rivals, he fills up on his back and press down to the ground.
After mating, a female chooses a cavity in rotten wood, where she lays her eggs.After all, the wood is rotten food substrate for the future larvae.In one year the female beetle can lay about 100 testes.
Larvae hatched from eggs, are beginning to eat the wood, moving through it.At the time of transition pupal larvae it may reach 180 mm in length and weigh up to 100 grams!And if during the stage of development of the eggs for about a month and a half maximum, the larva develops from a half to two years - well, no wonder you?Dolly is going through a phase of development in six weeks.
Adult Hercules Beetle prefers to use his diet soft overripe fruit.But if this food is for some reason difficult to access, the beetle may be using prehensile claws on their feet, to climb the trees.
Sometimes in search of food beetle can carry out a flight from one place to another.Its wingspan is 22 centimeters.
study of beetles - is interesting and entertaining.There is a science that deals with them - coleopterology.
