Host plants:
The larvae feed on Cassiope tetragona, but very probably also on other plants. From N-America Dryas and creeping Salix are reported. At least Dryas seems to be quite possible. This plant was common at some sites in Lapland (together with Cassiope).

Habitat:
Boloria chariclea inhabits tundra vegetation. It is often found on quite dry mountain slopes (in Lapland up to 1000m).

Life cycle:
The butterflies occur most often in July, but may appear already in late June and/or still in early August. In 2020 they have been abundant at Abisko and Kilpisjärvi. The larva hibernates twice. I recorded the pupa under a stone.

Remarks:
Boloria chariclea has an Holarctic distribution. In Europe, it is known from N-Scandinavia and N-Russia.
