The surrounding habitat was described as not recorded.
According to the GPS data the collection was in the Iceland boreal birch forests and alpine tundra WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).
