Distribution and ecology. Holarctic. Polyphytophagous. In the vicinity of Pevek, it inhabits a wide range of habitats, reaching a high abundance in dry biotopes with a predominance of wormwood ( Artemisia kruhsiana or Artemisia tilesii ); larvae were recorded from mid-June, adults — from July 4. In Anadyr River valley it was found mainly in a dry foodplain meadows, two larvae were collected in tussock sedge-moss tundra with dwarf pine. From Wrangel Island N. e. groenlandicus was previously listed without label data ( Khruleva 2009, 2014). Few specimens were collected on a dry south facing slopes of hills and river terraces with cryoxerophytic vegetation. A high abundance of this species on Wrangel Island (a total of 102 specimens) was recorded only once: in sweep-nets carried out on August 6 and 13, 2006 in a zoogenic herb-wormwood meadow (fox burrow) at the mouth of Vesely brook, but in subsequent studies of this biotope in 2015 and 2019 the species was not found.
