Natural history.

Most specimens of Philhygra pseudolarsoni  from NB were found in wetland habitats. Adults were sifted from litter, grasses, and moss on hummocks near water and sifting sphagnum and litter near a brook in eastern white cedar swamps, and treading Carex  hummocks and emergent vegetation in a Carex  marsh along lake margins. One individual was collected with a net between 16:30 and 18:00 h in a mixed forest opening during a warm evening. The type and paratypes from the YT were sifted from soil litter from deciduous and mixed forests ( Klimaszewski et al. 2012), otherwise little was previously known about the habitat associations of this species. Adults were collected during May and June.

Distribution in Canada and Alaska.

YT, NB ( Klimaszewski et al. 2012; Bousquet et al. 2013). Philhygra pseudolarsoni  was described from the YT ( Klimaszewski et al. 2012). The data presented here suggest that this species has a transcontinental distribution in Canada.
