|scientific name Catocala concumbens |
common name Sleepy or Pink Underwing
Riparian tall shrub and woodland edge; urban plantings.
Adults are on the wing in Alberta in August.
A large (6.0-7.5 cm wingspan) moth with pale slate-grey forewings and bright rose-pink hindwings. The forewings are even pale slate grey, crossed by thin jagged black antemedian and postmedian lines, and with some darker grey shading. The hindwings are astonishing brilliant rose pink, crossed by wide black median and terminal bands and with a wide pale buff fringe. The antennae are simple and both the sexes are similar.
Adults are nocturnal and come to light, but more commonly to sugar baits. The egg is the overwintering stage, and the larvae are solitary defoliators. There is a single brood each year.
Scarce at the western edge of its range in Alberta. No concerns.
No Alberta data. Elsewhere reported to use willows (Salix sp.) and poplars (Populus sp., including P. tremuloides, P. deltoides and P. nigra).
Widespread in eastern North America, west across the southern half of the Prairie Provinces to eastern Alberta. In Alberta, it has been collected along the eastern edge of the parklands, east to Dinosaur Provincial Park and north to Lloydminster.
