Collection and habitat data.

Most adults of Philhygra luridipennis from New Brunswick were collected from riparian habitats in various deciduous and coniferous forest types. Specimens were collected from gravel (splashing and turning gravel) on gravel bars along shaded brooks in a northern hardwood forest and a boreal forest with balsam fir and white spruce, hand collected from gravel and from under cobblestones on the margin of a clear, medium-sized stream in a mixed forest, sifted from debris on muddy soil near a brook in an alder swamp, hand collected from a sand and clay mix under alders near a river margin, and collected by splashing water on moss near the splash zone of a waterfall. Other specimens were collected at a mercury vapor light and with an aerial net during an evening flight near a mixed forest and nearby stream. Adults were collected during April, June, July, and September. Little was previously known about the habitat associations of this species. The male specimen from Newfoundland was captured in a flight intercept trap in a mixed forest ( Klimaszewski et al. 2011).
