Polubyanka Filipieva (lat. Celastrina (Maslowskia) Filipjevi) is one of the types of butterflies that belongs to the Pigeon Family and is one of the few endemics of Eurasia. The species is named after one of the most key researchers who managed to open many other members of the family Ivan Nikolayevich Filipiev. In addition, it was this scientist that was one of the founders of phytolgeminthology.
In terms of individuals of this type, quite average. The scope of their wings can reach thirtyfive millimeters. The color of males from above is mainly purple-blue shades, and a narrow black strip is located along the edges. The female is significantly different from the male representative, her regional drawing expands into a fullfledged border, especially this is noticeable near the top of the wings, where it continues throughout the size of the Kostelnaya region. The front and rear wings have a black pattern, which consists of strokes of different sizes, which can be located not only vertically, but also horizontally, as well as several rows of black dots.
Where it lives
Polubyanka Filipieva lives exclusively about valley mixed forests, as well as near shrub thickets, which germinate near the coast of various reservoirs. One of the prerequisite for the appearance of the population is the presence of sand and pebbles, since it is on them that the main fodder plant of caterpillars grows-the princes of Chinese, a bush, which is listed in the red book and is considered an endangered. All these factors are very similar to a different look, a dovec with Oreas, which, although it is endemic of the other region, is not particularly different from the Filipyeva butterfly in the way of life and the habitat.
Even despite the fact that no one spent any quantitative accounting, the number of this species was recognized as a critical. Because of this, the pigeon Filipiev is attributed to the first category of the Red Book. At the moment, only six populations throughout the country are known, which is a very small number and indicates the extremely high probability of complete destruction of the entire type. The main factor in the disappearance is climatic changes, as well as human activity, in the consequence of which the feed plant, Principia, disappears with a huge speed. According to scientists, if nothing is done with the cutting of the plant for fuel, then the whole species will disappear in the next five years, and it will already be possible to return it to any selection.
Butterflies begin to fly from the end of June, which means that the formation of caterpillars ends at that moment. All pigeons lay off their offspring in late autumn, the eggs winter, caterpillars are formed in them, which begin to eat a stern plant and pushing out at high speed. This entire period takes only a couple of months, from early April to late May or early June. The female lays her eggs on the ends of the leaves of the princesses, attaching them with the help of secretions so that no wind could blow them off. The doll is also attached to the feed plant, but already from below, and after two weeks a butterfly appears from it.
