Bionomic Notes. Philhygra botanicarum   was typically found in moist leaves (often on muddy soil) near the margins of vernal ponds or small brooks in alder swamps or mixed forests. Some adults were found in drift material on a lake shore and in

moist leaves under a sap flow from a recently cut yellow birch. Nothing was previously known about the bionomics of this species. Adults were collected in May, June and July. Collection method: sifting, U.V. light trap.

mens were collected from flood debris and drift material along river margins. Many adults were observed on the surface of gravel near the water’s edge on a gravel bar at the Nerepis River. Some individuals at this site were also found under small cobblestones. One individual was collected from moss near the margin of a brook in a mature red spruce and red maple forest. This species is considered to be adventive from Eurasia where it is common in natural habitats, although in North America most records of this species have been from disturbed habitats ( Gusarov 2003). In New Brunswick, this species was collected in May, June, and July. Collection method: sifting, hand collecting (turning cobblestones and pebbles on river margin).
