Near the southern end of it range in Vermont. Known from only two records: one at a spruce bog in the Northeast Highlands (2003) and the other from a grassy opening at 825 meters in elevation at the top of a ski lift in the Green Mountains (2004). No peatland associated with this latter record has been identified. Additional investigation may yet reveal more sites for A. subarctica in Vermont. True to the nature of this species (T. Donnelly, pers. comm.), individuals encountered at the bog site seemed to prefer areas with saturated Sphagnum moss.
