Scattered at mid- and upper-elevation lakes and ponds. Most records from the Green Mountains and Northern Piedmont. The mean elevation is approximately 1840 feet, with no specimens collected below 400 feet. Yet to be found in the Champlain Valley or Connecticut Valley. Walker (1912) notes A. eremita as abundant in northern Canada, becoming more local in the transition zones to the south. Vermont is at the southern edge of its range. Abundance at a given site can vary widely. Huge numbers of exuviae and adults observed at Lewis Pond in Northeastern Highlands, but also found in low numbers at sites among other Aeshna species.
