Collection of moths and butterflies in the city of Arkhangelsk, Solovetsky Islands,
Pinezhsky and Kargopolsky districts carried out between 2017 and 2019, and identification of occasional samples resulted in the discovery of 47 species of Lepidoptera
not previously reported from the Arkhangelsk Oblast; three more species were added
to the regional fauna based on published data. Especially noteworthy are the findings
of Coleophora proterella (a recently described species; the first record from Russia),
Clostera albosigma (the westernmost European record) and Bryotropha affinis (a rare,
mainly coastal species in Fennoscandia). We also confirmed the records of eight species known from old publications only, and we report new localities for 318 species.
To date, the known fauna of the Arkhangelsk Oblast totals 1188 species of moths and
butterflies (639 species of microlepidoptera and 549 species of macrolepidoptera); 62
of these are classified as threatened in Finland. We estimate that the regional fauna of
Lepidoptera amounts to 1800 species.
