Phenology. This species has the longest flight period among Novaya Zemlya bumble bees that lasts from early June or mid-June to late August ( Fig. 8A ). Its workers are appeared in early July, while the flight of males starts in late July.

Distribution. Yuzhny Island and the southern edge of Severny Island of the Novaya Zemlya Archipelago, probably also Wrangel Island ( Berezin 1990; Chernov 2008; Potapov et al. 2018a). The records from the Kanin Peninsula and Kolguev Island ( Poppius 1908; Pittioni 1943) are highly questionable ( Potapov et al. 2018a).

Taxonomic comments. The results of our previous integrative study indicate that Bombus glacialis is a separate bumble bee species that is phylogenetically and morphologically distinct from the other taxa in the B. lapponicus complex ( Potapov et al. 2018a).
