The scientific name of the hayfly is Coenonympha pamphylus L. It is a day butterfly of the family Marigolds. It is very hard to see, this species is considered endangered. Butterfly Sennitsa migrated to Eastern Europe, because it is very hard to endure cold winters.
In Germany, the marsh sennitsa was completely exterminated, because. it completely wiped out the cornfields, the peppers, the entire tomato crop, and practically all the flowers.
Sennitsa feeds on the juices of plants, rotting fruits, moisture from roadside puddles, mineral salts from various feces, etc. The butterfly is shade-loving, flies in cloudy weather, and on hot days hides under the canopy of the forest.
The butterfly Pamphilus sennitsa, which is also called the "small yellow satyr", belongs to the Satyr family. From Greek to Russian, the word "Pamphilus" is translated as "beloved by all" and is used as a name for a man.
Habitat
This genus of diurnal butterflies is quite common all over the world: beauties can be found in Europe, mainly eastern, in the Caucasus Mountains, Asia, both Front and Middle, in Western Siberia and Mongolia, North Africa and on the Crimean peninsula. Butterfly sennitsa does not live only in the northern tundra, where the conditions for its living are too harsh and difficult.
The marigold family lives on:
- all types of meadows and clearings;
- forest edges and river banks;
- roadsides and agricultural lands;
- wastelands and pastures;
- glades and gardens.
Sennitsa pamphil especially loves to be in areas densely planted with cereals.
The active flight of these insects begins at the very end of April and lasts until the end of October. The butterfly is not particularly shy, it flies slowly, sits on plants with pleasure and feeds on flower nectar.
Appearance
Sennitsa pamphilus is a genus of diurnal butterflies, which are distinguished by their small size. In appearance, it looks like a swamp sennitsa (larger and without bright edges on the wings).
Description of the pamphilus butterfly:
- Head: crowned with bare eyes, without framing with hairs.
- tendrils: uniform, club gradually thickening.
- The appearance of the wings: with rounded edges, painted in shades of yellow, brown and red tones.
- rear fenders: the submarginal field is covered with rather large eye spots and veins that do not differ in color contrasting with the general background. The veins on the wings branch from the central part from two projections. On the lower part of the limbs there are spots in the form of an eye pattern and light stripes.
- front fenders: have 2-3 swollen veins at their base. The underside is painted in an orange hue, with eye spots.
When the sennitsa is at rest, it does not show to others the upper surface of its wings, which is very picturesque: an orange-brown surface with gray edges and eye-shaped spots located in the upper part of the front of the wings.

Interesting features
Common sennitsa gives a different number of generations, this figure depends on the latitude in which it lives and seasonal conditions.
- In the northern latitudes, only one generation of butterflies has time to develop, and the active flight of insects begins in July.
- The middle lane, with its climatic conditions, makes it possible for the development of two generations of butterflies, and their flight continues from the second week of May to the third week of June. The second round of development lasts from mid-July to the second week of September.
- The southern territories allow butterflies to grow at least three generations, the timing of the flight of which can vary and even reach October.
caterpillars
Caterpillars of the pamphilia sennitsa develop either at the very end of spring or in the first weeks of summer. The last generations can winter from the end of autumn to warm spring days.
The appearance of the caterpillars is distinguished by pinkish or green hues, with longitudinal stripes and a dark back with a light frame. The head of the caterpillar is green with light sides.
Caterpillars of the Sennitsa often hide in plants, especially fodder ones. They are very active at night when they come out in search of food (most often it is the foliage of fescue, pike, bluegrass and white beard). The caterpillars that have caught the winter turn into pupae, located next to the soil. Caterpillars that have developed are placed on the stems of plants, vertically down. Scientists around the world are fighting for the safety of this species of butterflies, despite their harmfulness.
