Zhumoi Caucasian is a rather large representative of the Zhukla family, widespread in Eurasia, in particular, in the north of the Mountain Caucasus. Some individuals are found in the Krasnodar Territory.
How it looks
The appearance of the Caucasian beetle is characterized by a bright bluish-green color with a purple tint. Odlalli have a rough texture. The front of the back is very narrowed in front, and the surface of the body has a granular and wrinkled coating. The color of the lower body of the body is black with a metal tint. The body length of this Caucasian representative ranges from 32 to 50 millimeters. Sexual dimorphism is expressed in the difference in size: females are more overall than males. This representative is listed in the Red Book of Eurasia insects, since the number of individuals is adulthly reduced.
The main habitat for this subspecies beetles are dry forests and oaks. Some individuals get to mountain and meadow steppes up to 2000 meters above sea level. Quite often, the Caucasian beetle is found in parks and gardens, and can also populate other cultural territories near the main habitat.
Caucasian beetle is considered a predatory insect. In her diet you can find types such as:
- Slugs and snails.
In order to catch and neutralize the victim, the beetle injects a special secret, which is located in his jaw apparatus. This composition, having entered the body of prey, dilutes its internal organs, as a result of which the beetle can calmly enjoy its find. The process of digesting food of this representative can occupy several days, during this period he returns to shelter, where he spends time until the next hunt. Hunting is mainly in the dark time.
Most insects do not live longer than a year, but the Caucasian beetle is an exception. The life expectancy of the species reaches up to 3 years, and under good conditions it can live and all 5 years. The Caucasian beetle has all the stages of complete transformation: egg, larva, doll and imago. The beginning of the period of propagation of these individuals is in the spring, as a rule, from April to May. The female lays from 70 eggs for only one masonry.
Caucasian beetles are very picky in choosing a place where their larvae will develop. Choose raw and warm land into which sunlight does not penetrate. Before laying down her eggs, the female digs out a small hole with a depth of at least three centimeters. The period of metamorphosis of the egg in the larva takes two or more than a week. The formed larva is obtained up to 2 centimeters in length. The first few hours of the larvae of the Caucasian beetle have a white color, but then they begin to darken until they become black. In such a role, larvae spend time until the end of the summer season, and live and eat as well as their adult associates.
In order to get food, the larva of the Caucasian beetle has a welldeveloped jaw apparatus, which is in adults. The transformation into a cocoon falls out at the beginning of autumn, and it becomes a fullfledged Caucasian beetle only with the advent of spring.
Caucasian beetles are carnivorous predators, many species of ants and birds do not mind enjoying eggs, larvae and beetles themselves. Many badgers and hedgehogs are a potential threat to this type. Caucasian beetles can become a snack for bears and wild pigs. However, the largest pests for the development of the population are ants that climb into the shelter refuge and eat their larvae and eggs. Ants do not risk attacking adults, since because of their small dimensions they themselves will become a victim of an insect.
It is amazing that the Caucasian beetz is feeding on many insects-pests, so this representative has only a positive effect on the development of agricultural crops. However, many people do not know about this, so at the sight of this representative they try to destroy it right away.
The population of the Caucasian beetle is at risk, and with the goal of preventing an even greater reduction in the species, this representatives entered the Red Book of Eurasia and Georgia.
