Mnemosyne (Parnassius mnemosyne)
In Russia, it is found in the European part (excluding the north), in the southern Altai. It lives on the territory of all the republics of the former USSR, as well as in Western Europe, Asia Minor, and the Middle East.
The population is steadily declining. In some cases, the loss of individual populations is observed.
The species is represented by a number of geographically isolated populations. It is found in flat areas, as well as in mountains at an altitude of up to 2000 m above sea level, sometimes even higher. Prefers moist meadows and large clearings in shady forests, more often on slopes. Butterflies fly from late April to mid-July. One generation per year. Caterpillars are found in April-May or from August to May. In the first case, eggs with formed caterpillars overwinter. During the day, the caterpillar hides in leaves on the ground, and at night it feeds. Various species of crested beetles, especially Corydalis solida and Corydalis cava, serve as food plants. Caterpillars were also observed feeding on sedum and Prenanthes [1]. Pupation occurs on the ground in leaves, in a relatively dense cocoon.
Possible reasons for the decline in numbers are the reduction of territories occupied by old shady forests, due to excessive logging and the collection of crested plants.
