Stages of development
The insect passes through several stages - an egg, a larva, a nymph, an imago. The mating season, reproduction begins in May, the whole warm period lasts. As the bear multiplies, it looks beautiful, melodious.
The male has singing ability and arranges real trills at night with different modulations, chattering. In this way, attracts the attention of females. Mature females crawl out of their burrows, rise into the air, fly towards their fate. Able to overcome up to 8 km.
Stages of development of the bear: after fertilization, the female is taken for the arrangement of her own home, the nest. The depth of the structure depends on the characteristics of the soil. In black soil with high humidity, the shelter is located at a depth of 5 cm. In the sandy, dry - 15 cm. But it can reach up to 70 cm inland.
When the bear lays eggs, the common bear lays eggs 2 weeks after fertilization. In one laying from 25 to 60 pieces. Eggs of a bear about 1 mm in size. The female provides optimal conditions, takes care of the safe breeding of offspring.

Photos and description of the larvae below.Before that it looks like a caterpillar, reminds grub beetlebut has some differences.
How much an insect lives - the formation of imago is slow. It takes about 2 years for the larvae to mature. During this time, the individual passes about 10 molts; at the last stage, the genitals are formed.
On a note!
The adult individual lives about 1.5 years. In artificially created conditions - 3 years. The entire life cycle lasts about 5 years.
Where the pest lives - the family hibernates deep in the ground. The nest is built at a distance of 2 m from the surface. Can settle under a pile of manure or directly in it. With the onset of heat, when the soil warms up to 12 degrees, it activates its activity. There are traces in the garden, the results of sabotage.

Laying eggs occurs at a time when the beds seedlings are planted, because of what many gardeners have to save her.
On a note!
Numerous labyrinths are located underground at a depth of 5 - 70 cm. It all depends on soil moisture. With a lack of moisture, the larvae either do not hatch, or die immediately after birth.
