Natural history.

In NB, Blepharhymenus brendeli  adults were found near shaded brook and stream margins, near vernal pools near brooks, and in mossy seepage areas in hardwood forests, old-growth eastern white cedar forests and swamps, in a mature spruce and cedar forest, and in alder swamps. Specimens were found in saturated moss on rocks near flowing water, in saturated moss and Carex  litter in seepages, in leaf litter in areas with Carex  near brooks, in moss and litter, and in moss, sphagnum, and leaf litter near brooks in the above habitats. The QC specimens were collected in an oak–beech–maple forest, by sifting deep, moldy leaf litter along bases of large rock blocks, and in a small seepage under a hydro line with large ferns, dogwood and Salix  , and by sifting layers of moist dead fern leaves and detritus under ferns. Nothing was previously known about the habitat associations of this species. Adults were collected during April, May, June, July, and September.
