Bionomic Notes. Oxypoda lacustris appears to be a hygrophilous species associated with wet habitats of various kinds. In New Brunswick, adults were captured in marsh litter in a cattail/sedge marsh, in leaf and grass litter at base of red maple in a Carex marsh, in leaf litter in silver maple swamps, in moist leaf litter on margins of vernal ponds in mixed forests, and in drift material on a lake margin. Adults were collected in late March, April, May, June, and July. Collection method: sifting.
