Medvedka is an insect that looks very unattractive, not to say threatening. And the harm that she can inflict on your garden is tantamount to her unpleasant appearance.

Devouring not only shoots and fruits, but also the root system, the pest can destroy the entire crop. Therefore, it is necessary to fight against it, and in order to win it is necessary to know the "enemy by sight".

From this article you will learn what the bear is, in what conditions it lives and reproduces.

Environment and habitats

Medvedka nests and lives in both sandy and heavy clay soils. Especially loves humus-rich soil, moist and nutritious.

Therefore, it can often be found in gardens, vegetable gardens and flower beds. Leads underground life, coming to the surface mainly during the breeding season (May-June).

This insect is widespread throughout almost all of Europe (exceptions: the Far North, Finland, the Netherlands).

She is found in Kazakhstan and the Caucasus, lives in the European part of Russia, except for the northeastern and northern regions.

About what the pest looks like, its description, everything about the origin, as well as photos and sizes of the bear, see below.


Appearance and dimensions

Medvedka got its name for a clumsy oblong body of dark green color with dense dark brown pubescence on the upper side.

The underside has hairs of a dark yellow, sometimes olive tint. The pectoral shell is strong, solid and has such a structure that the head of the pest, in case of, for example, danger, can hide under it.

Medvedka's head has medium-sized eyes, between which there are two accessory eyes, a long mustache and 4 tentacles that frame a mouth with strong jaws.

The forelimbs differ from the other four in their modification - shorter, more massive and powerful, they are suitable for both digging and swimming.

The forewings are short, round-triangular in shape. The hind wings of the insect are very developed, which helps the insect to cover great distances in a short time.

The folded wings are two long thin scales that exceed the length of the abdomen and look like two tails. The body length of an adult of the common bear reaches 60 mm, and the thickness is 15-20 mm.

Interesting: "Medvedka" is not the only name of the insect. For the gray color of young animals and "pirate" manners it is called "top", and for the presence of powerful claws - "earthen crayfish".

What does it eat?

Medvedka is a polyphagous insect that eats wild plants, field and vegetable crops, seedlings of forest and garden trees.

In addition to plant food, the bear uses the larvae of insects living in the soil, worms. There are frequent cases of eating self-like bears.

Most of all, the bear loves cabbage, potatoes, corn, beets, hemp and carrots. But for the great "love" for cabbage, the people nicknamed the bear - cabbage. Here it is worth noting that the bear eats both plant roots and young shoots, and the fruits themselves.

What kind of plants doesn't he like?

Although the bear is considered a gluttonous and polyphagous insect, there are plants that she does not tolerate.

The pest does not tolerate marigolds and garlic on the spirit. If these crops are planted on the planting lands, the bear will bypass them.

Medvedka: a beetle or an insect of another kind?

Medvedka is an insect that belongs to the family of large burrowing insects of the Orthoptera order. Beetles belong to the Coleoptera family. They all belong to the class of insects.

Ten-fingered bear

A close relative of the common bear is the ten-fingered bear. The body length of an adult does not exceed 35 mm, and the thickness is 8-11 mm. It feeds on plant roots, young shoots and leads an underground lifestyle.

The main natural enemy of the insect is the burrowing wasp, which attacks the bear in its hole, stings (with a paralyzing poison) and uses it as an incubator for its eggs.

Ten-fingered bear


How does an insect reproduce? In May-June, when the air temperature stably reaches + 12- + 15 ° C, there is a massive exit of adult insects to the surface, where mating takes place.

After that, it goes into the ground to a depth of 8-10 cm and begins to equip the nest and lay eggs. The female lays from 300 to 500 round-oval dark yellow eggs with a diameter of 1-2 mm.

Each egg is covered with a dense shell that protects it from damage. For the full development of masonry, certain conditions are required: air humidity close to 100%.

Development cycle

The stages of development of the bear are as follows:

  1. Eggs.
  2. Larvae.
  3. Nymphs.
  4. Adults.

The second instar bear larvae or nymphs are born in 14-20 days. These are miniature insects of gray-white color, which practically do not differ in external structure from an adult. The only difference is the lack of wings.

Larvae of the bear


After the birth of the bear, they are blind for the entire period until the first molt., therefore, for some time they are in the nest, where the parent creates all the conditions for their existence. After the first discharge of the chitinous layer, young bears leave the nest, starting to live independently.

The developmental cycle from nymph to imago takes place in stages and ranges from 18 to 24 months.

How many lives?

After the entry of the bear into the adult stage, its life span is 1 year, from the moment it emerges from the egg, respectively, 3 years.

How and where to find a bear, read on. Read about whether a bear bite is dangerous for a person in this article.


The insect nest is truly unique! It is represented by a small underground space at a depth of 10-15 cm. Around the “family hearth” tunnels have been dug and there are four exits to the surface along the edges.

The female laying eggs is able to close and open these passages, thereby regulating the temperature and humidity in the nest, creating the best conditions for the development of eggs and newborn larvae.

In the nest, the female gnaws at the roots of plants, thereby destroying all vegetation on the surface, so that the sun warms up this piece of land as much as possible.


An earthy bear digs underground passages up and down, only around the nest they are lined up in a spiral, one end of which leads to the nest, and the other to the surface.

From the holes of the minks into the depths, the bear breaks through "adits", which serve to drain excess water.

Footprints on the ground

In order to determine the measures and methods of dealing with the bear, you need to make sure that this is it. This can be done by looking at the surface of the earth, where you can find entrances to the bear's burrows.

Medvedka digs moves both horizontally and vertically. The horizontal passages are not visible, as they are under the surface at a depth of 2-2.5 cm, but the vertical ones are easy to notice.

Footprints appear as regular shaped holes in the soil surrounded by a small mound of earth.

The entrance to the hole

Where does it come from?

Where does the bear come from in the garden? Often, it enters the land with manure, in which the larvae of this pest live. It can wander from neighboring areas if your soil has higher moisture and nutritional properties.


No matter how terrible the pest is, you need to deal with it, and in the case of a bear you can fight.
