Hylastes porculus

Genus / Species: Hylastes porculus | Image Author: J Buffam | Location: United States, Virginia, Virginia (state) | Image Type: holotype | Collection: Canadian National Collection of Insects, Arachnids and Nematodes

According to Wood (1982: 105) this species is very closely related to Hylastes nigrinus (Mannerheim) and may in fact be a synonym. As treated by Wood, these species are largely allopatric with nigrinus found in the Rocky Mountains westwards and porculus to the east, both absent from northern central Canada. In fact these are mostly identified based on locality, rather than morphological characters.
