Colias palaeno palaeno (Linnaeus, 1761)

Specimens: 6\SE Efremkino, 1♂, 1♀.

Observations: This species is mostly associated with peaty habitats, such as raised bogs or peaty taiga, but strays, mostly females, can be found everywhere. Our finding of two individuals of both sexes in the Belyy Iyus valley was nevertheless unexpected: there was just an open larch and birch stand rather than humid taiga, on calcareous soils of basic reaction, in contrast to acid soils of the preferred habitats of this species.

Colias hyale hyale (Linnaeus, 1758) Specimens: 1♂; 4\WNW Shira, 2♂; 6\SE Efremkino, 1♂; 7\Sonskiy, 3♂, 1♀; 9\Terensug headwaters, 1♂.

Visual registrations: 1\NNE Parnaya, many; 2\NE Kopyovo, 1♂; 12\Dzhabash, few 1♂.

Observations: Prefers meadows ruderal vegetation, and we observed the same in Khakassia but this species occurred at natural meadows as well, mostly near hill crests.
