Beetles are the most diverse representatives on the planet. There are about 250 thousand of them. In Russia alone, there are about 13 thousand species. They are predators and herbivores.
Instructions
Step 1
Beetles are found everywhere: underground, in water, in trees and in the mountains. They can fly long distances. Beetles feed on plant food and insects. Some of them bring great harm to humans by eating cultivated plants. All beetles are assigned to one detachment - coleoptera. The main similarity of all insects are wings. The two lower wings serve them for flight, and the upper, solid ones, are designed to protect the thin wings and abdomen.
Step 2
The titan lumberjack is the largest representative of beetles. It can grow up to 18 cm in length (some sources indicate its size up to 26 cm). Females are much larger than males. The titan lumberjack is mostly nocturnal.
Step 3
Almost everyone knows the ladybug. It is easily distinguished by its orange or bright red color with black dots. These are very useful insects that are capable of destroying thousands of aphids in their entire life. It is appreciated by gardeners and put a lot of effort to lure a ladybug.
Step 4
The Colorado potato beetle can only fly in adulthood. As a rule, young beetles have undeveloped wings. He flies only if there is no food left on his territory. Most often, the beetle can be found on potato plantations.
Step 5
The May beetle was practically destroyed in Central Europe, due to the damage to the forest. It goes a long way in its development. After the females have laid eggs, larvae emerge from them. They feed on the roots of plants, thereby bringing them great harm. The larvae pupate only in the third year, and in the fall they turn into beetles. May beetles come to the surface only in spring.
Step 6
The Hitler Beetle lives in Slovenia in caves. It got its name in the 30s, after a scientist discovered it. He decided to glorify the Fuhrer and named the beetle in his honor. Although this beetle is completely harmless to humans.
Step 7
Dung beetle or scarab beetle lives and feeds on animal dung. It is only 4 cm long. In Ancient Egypt, the scarab beetle was considered sacred - the guardian of many temples.
Step 8
The stag beetle is so named because of its large head with "horns". These "horns" are nothing more than a jaw of an unusual shape. It is a herbivorous beetle and feeds on the sap of oak bark. Females are much smaller than males, but their jaws are more powerful. The number of the stag beetle has dropped sharply in recent years, so it was listed in the Red Book and is protected by law. Under no circumstances should you catch him and kill him.
