Lumberjack Relikbook from the Red Book photo and description of the beetle, how it looks, where it lives, what it eats

The lumberjack relic is a detachment of hard winged. The insect large sizes with a long mustache received this name due to the fact that it lives in the trees. This representative has two more names the Ussuri Lumberjack or Usach.

How it looks

On the territory of Eurasia, it is considered the most overall representative from the entire detachment of harshly winged. The size of females varies from 60 to 90 millimeters, and the dimensions of males can reach 110 millimeters. It is also notable for the fact that it is the only tropical beetle that settled the territory of Europe, Africa and Asia.

The external difference between the Ussuri lumberjack lies in the smooth jaws and the elongated body structure. Because of this feature, the lumberjack’s mustache look short, although in fact they are very long.  The body of these insects is painted black with a chestnut tint on the overlap. There are small white spots on the frontline. Sexual dimorphism of these representatives lies in the length of the mustache and the presence of small points on the elytra. The mustaches of males are longer, and on the overlap them are smaller than small points.

Habitat

This representative of the hard winged is a rather rare phenomenon. However, its territory is quite wide. Ussuri beetle is located in Asia, Eurasia and Europe. In Eurasia, this species is on the northwest side. Also the natural territory of the Ussuri lumberjack is the forests of South Korea, North-East China and the DPRK.

Food

The whole life of a relict lumberjack has a direct connection with a tree. These representatives settled broadleaved and pine trees. The basis of their diet is wood juice and the bark of young branches. Adult relict lumberjacks feed on linden juice, birch and elm. Sometimes they can eat pollen and leaves. Adults are not as voracious as larvae. It is larvae that are serious pests for many plants.

Behavior in nature

The behavior of the Ussuri lumberjacks is determined by their habitat and climatic conditions. Southern representatives are flying since midMarch, in other areas from the beginning of autumn. These insects are activated in the light of day, and night is spent in their wood shelters. The larvae of the relict lumberjack spend all the time in the wood of fatbarreled trees.

These representatives of the beetles are not the best flyers. While in the air, a relict lumberjack looks extremely awkward, experiencing problems even when raising. All this is due to relatively large dimensions.

Females of Ussuri lumberjacks fly a little better, thanks to their smaller sizes.

Due to their strong jaws, lumberjacks can easily cope with the wood bark, and they can even easily gnaw a thick pencil.

Enemies

Woodpeckers and other representatives of the Dyatlovs detachment are extremely dangerous for beetles. They can easily destroy adults of relict beetles. Quite often, these large beetles become the prey of other predatory birds and mammals. If the relict beetle is near the ground, then the danger of an attack is increasing.

The state of Ussuri beetles and various parasitic microorganisms: ticks and bacteria are poorly affected. At least they do not immediately kill the insect, but strongly undermine its condition.

Many people deliberately hunt for this representative, since it is of great importance in the black market. And collectors are ready to pay a lot of money to replenish their collection with such an amazing creature.

Reproduction

The marriage season of relict beetles begins with the arrival of spring. Males attract females with a special secret. The process of fertilization itself lasts about 30 minutes, after which the male carries out the female to the place of laying eggs. Up to 28 eggs go out for one masonry. They use fodder trees trunks as a place so that the larva can fully eat and grow. Literally the next day, the male and the female die.

In the larval stage, representatives of relict beetles make moves in the bark of the tree. In the selected place are before turning into an adult beetle. As a rule, a pupa of a relict beetle is formed in the summer. And its development lasts no more than a month, after which the beetles reach adult sizes.
