Bionomic Notes. Oxypoda demissa appears to be a hygrophilous species associated with wet habitats of various kinds. In New Brunswick, adults were captured in moist leaf litter on the margin of a vernal pond in a mixed forest, among leaves and sedges on pond margin, in moist grass litter and sphagnum in Carex marsh, among sedges along margin of small spring-fed brook in a mature hardwood forest and among leaf litter and grass on hummocks in a wet alder ( Alnus sp.) swamp. In Nova Scotia, this species was reported from litter of Alnus clumps (Klimaszewski et al. 2006). A number of adults were collected with a net during late afternoon (15:00 to 18:00 h) flights. Adults were captured in April, May, June, and July. Collection method: sifting, some collected in flight with net during evening.
