Natural history.

Most specimens of Stenus formicetorum were found along a lake margin with emergent vegetation of Carex and grasses. Adults were collected by treading vegetation into water. One individual was sifted from leaf litter along the margin of a beaver pond, one was sifted from drift material (tree bud material) near an eddy area along a small rocky, clear, cold river margin, and another adult was captured in a Lindgren funnel trap in the canopy of a red oak in a mixed forest. This species was collected in May, June, and July in NB, and September in ON.
