As with other species of the genus, P. angusticauda is associated with riparian habitats.

Comments.

Philhygra angusticauda is a Holarctic species that was previously recognized in the Palaearctic (Finland, Norway, European Russia, Russian Far East) ( Schülke and Smetana 2015; Newton 2019) under the synonym P. pinegensis (Muona). We newly report this species from Alberta and suggest that it broadly occurs across northern Canada. Specimens from the Nearctic and Palaearctic were found to have identical genitalia and their DNA barcodes form a cluster with only 0.3% divergence between Finnish and Canadian specimens.
