Medvedka is a thunderstorm of gardens and orchards. This insect lives throughout Eurasia, with the exception of the Scandinavian countries, and is one of the worst enemies of gardeners and gardeners.
Instructions
Step 1
Medvedka belongs to the species of orthoptera from the family of the same name. This insect is considered one of the largest garden pests - the length of the bear's body (without cerci and antennae) is 5 cm. The abdomen of the bear is soft, spindle-shaped and noticeably larger than the cephalothorax. The diameter of the abdomen of an adult is about 1 cm. The entire body of this insect is covered with fine hairs. Above, the bear is brown, and below it is dark yellow. The abdomen of this insect ends with two antennae (like in a two-tailed), called cerci.
Step 2
The front legs of the bear are shortened and are designed to dig the ground with them. By the way, the second name of the bear is earth crayfish: the insect looks like a crayfish, and it also lives in the ground. Bears can fly because they have wings. When folded in an adult, the wings look like long and thin scales that exceed the length of the abdomen itself. In order for the bear to take off, she needs warm air, otherwise the muscles of her wings will not be able to work properly. Males can chirp with the help of the elytra.
Step 3
The pectoral shell of the bear is hard and partially protects the insect: its structure allows the pest to hide its head under protection. The bear's head has two huge and complex eyes, as well as long antennae-shaped whiskers and two pairs of tentacles that frame the insect's mouth apparatus. This pest is widespread throughout Eurasia (except Finland and Norway) and in North Africa. In Russia, the bear can be found throughout the European part, with the exception of some northeastern regions of the country.
Step 4
Medvedki are predominantly nocturnal. They swim great and run great. Such love for water forces them to break through long burrows near its sources, however, these insects practically do not appear on the surface. At night, the bears make long flights from one place to another.
Step 5
The harm of the bear is that they damage the appendages and roots of plants, bulbs and fruits, seeds: the insect makes tunnels underground, gnawing the roots of cultivated plants. That is why many gardeners and summer residents put the fight against bears as a priority. It is worth noting that agriculture is directly harmed by three types of these insects: common, Far Eastern and single-thorn bears. By the way, these pests also bring some benefits: for example, by breaking through their underground passages, bears improve soil aeration.
