BNA: Hoary Comma ; Polygonia gracilis (incl. zephyrus )
NDC: POZE

Habitat: Mountain forests, especially near water; occurs in Riding Mountains, Manitoba, but all known ND records have been traced to misidentification of P. progne from Billings, Slope, and Bowman Counties. ND occurrence is therfore subject to question pending clear confirmation

Adult flight: Univoltine, flying in July
References: Royer 142, Ferris & Brown 340, Layberry et al. 200 (as P. gracilis ssp.), Scott 286 (as P. gracilis ssp.)
