Abstract

Many Corydalis DC. species are a nutritive base for worms and butterflies from genus Parnassius Latr. The trip to Yakutia in June — July 2015 aimed to discover relationships between these plants and insects. Some authors distinguish C. sibiriсa (L. fil.) Pers. as a forage plant for swallowtail butterfly Parnassius tenedius Eversmann and consider sporadic expansion of the butterfly depending on distribution of C. sibirica (Gluschenko, 1996; Korshunov, 2002). The distribution range of C. sibirica covers an area from the Arctic Siberia to Mongolia and Northern China (Heilongijang, Jilin, Inner Mongolia); isolated localities are known on the outskirts of eastern Ural Mts., along the Kakva River; as well as in Chukotka, Kamchatka (rarely), the Magadan Region and Khabarovsk Territory. Along its whole range, С. sibiriсa occurs on more or less disturbed habitats.

Plants with white flowers and intensely dove-coloured leaves were found nearby Kubume village in Oymyakon District of the Republic of Yakutia, side by side with common yellow-flowered ones. Laid eggs of the swallowtail butterfly were noticed only on С. sibiriсa with yellow flowers and did not present on white-flowered plants. Probably, the changes of flower colour will prevent these plants from being a fodder plant for Parnassius tenedius. The plants with white flowers are described as a new variety.
