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.
