IdentificationA mid-sized geometrid with rich, orange-brown wings marked with dark AM and PM lines, the later bordered with pinkish-purple distally. Hindwings slightly paler, with coarse black speckling at the anal angle.
Similar to P. alcoolaria, which has a straight PM line, a forewing discal spot, and is paler overall with a more speckled appearance. P. phlogosaria may have two broods in the southern parts of the province. Munroe (1959) described the subspecies bowmanaria from specimens from the Edmonton region.
