Natural history

Astenus americanus was found in moist leaf litter, sphagnum and leaf litter, and in moist leaves on the margin of a vernal pond in forested wetlands. These included a red maple swamp, eastern white cedar swamps, mixed forests with cedar, a red maple/alder swamp, and a small sedge marsh in a mixed forest. Some individuals were found in a calcareous fen and a Carex marsh. Adults were collected in April, May, and June.
