Vize Island, located in the northern part of the Kara Sea (79°30’N, 76°59’E),
is one of the least studied islands of the Russian High Arctic in terms
of its biota. Hundreds of live and freshly dead individuals of Larch
Budmoth Zeiraphera griseana
(Hübner, 1799) were observed on this island from 16 July–2 August 2020.
This is the first and the only terrestrial invertebrate ever discovered
on Vize Island. The moths were likely transported to the island by air
currents from the northern part of the Krasnoyarsk region, where an
outbreak of Z. griseana
was reported on over 75,000 ha. The distance travelled by moths
approached 1200 km. Thus, the high Arctic islands are less isolated from
insect migrants than was commonly thought. These islands will be
colonised by boreal insects as soon as changing environmental conditions
allow the establishment of local populations.
