Bionomics
In Newfoundland, one female was collected in a pitfall trap in a mixed boreal forest in July. In New Brunswick, Atheta giguereae was found in mature and old-growth eastern white cedar swamps, a mixed forest, an old-growth northern hardwood forest, and an old white pine stand (Webster et al. 2016[1]). Adults were sifted from moss and leaf litter near streams and brooks and from moist moss in these forests (Webster et al. 2016[1]). A few individuals were captured in Lindgren funnel traps. Specimens from Nova Scotia were captured in flight intercept traps in red spruce and red spruce–hemlock forests (Webster et al. 2016[1]). Adults were collected from April to August.
