Natural history.

In NB, Philhygra larsoni was found mostly in wetland habitats. Adults were found by splashing sun-exposed moss-covered rocks in a small river, treading Carex hummocks into water along pond margins, treading vegetation near a small pond in a seasonally flooded marsh, sifting moist grass litter near stream and pond margins, a red maple swamp, and sedge marshes, sifting grass and leaf litter on a hummock in a wet alder swamp, and sifting drift material on a lake margin. Nothing was previously known about the habitat associations of this species. In NF, Philhygra larsoni was collected from May to August without specific habitat data (Klimaszewski et al. 2011); in NB, adults were captured from mid-April to mid-August.
