Occurrence of Borearctia menetriesii (Eversmann, 1846) (Erebidae: Arctiinae) in Northern European Russia: a new locality in a disjunct species range

Disjunctive distribution is typical for the transpalaearctic tiger moth Borearctia menetriesii (Eversmann, 1846) (Erebidae: Arctiinae) at the present time. The new discovery at the East European (Russian) Plain modifies the previously known distribution pattern of this species. A specimen of this moth was recorded on a small patch of a humid mixed-herb meadow on the forest karst landscape of the White Sea-Kuloi Plateau. Its location is in the upper part of the Sotka River Valley and is surrounded by northern primary forest of spruce with inclusions of larch patches. It is characterised by a cold microclimate. This paper summarises data on previously known localities of B. menetriesii that are situated mainly within the Russian Federation and analyses the species distribution using Bailey's Ecoregions system.
