|scientific name Plagodis phlogosaria |
common name The Scorched Wing, Straight-lined Plagodis
Deciduous and mixedwood forests and woodlands.
The peak flight in Alberta is from mid May to early June.
A 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.
Caterpillar grey with light brown and white speckling, with abdominal and thoracic humps, giving it the appearance of a short twig. The pupa overwinters (Wagner et al. 2001). Adults come to lights.
Not of concern.
Larvae feed on willow (Salix), alders (Alnus), birch (Betula)and hazel (Corylus) (Prentice 1963).
Coastal BC east to Newfoundland, south from NWT to NC and CA (McGuffin 1987).
