Natural history
Most specimens of Stenus pluto were found along lake margins (two sites) with emergent vegetation (Carex, Carex hummocks, and grasses). Adults were collected by treading vegetation into water. One specimen was sifted from drift material (tree bud material) near an eddy area along a small rocky, clear, cold river margin and another was found among cobblestones along a large shaded brook. This species was collected in June, July, and August in NB.
