scientific name    Notodonta simplaria    

common name     Simple Prominent

habitat
Deciduous and mixedwood forest.

seasonality
Adults are on the wing from mid-May through mid-August, larvae from June through September.

identification
A rather large (4.0-5.0 cm. wingspan) robust moth with dark powdery grey forwing and a lighter grey hindwing. The lines are black, waved between the veins, and faintly outlined with light scales. The most prominent marking on the forewing is the small, vertical bar shaped reniform spot, outlined in white scales. The hindwing of the male whitish shaded with pale grey, especially on the anal third, and with a dark discal mark and grey veins. Female similar, but with darker hindwings. Male antennae are narrowly pectinate and with a simple tip; females have simple antennae. N. simplaria bears a superficial resemblance to large specimens of Panthea and some Polia, especially Polia rogenhoferi fm. carbonifera. The small, bar-shaped reniform with the pale border will separate simplaria from similar species.

life history
Adults are nocturnal and come to light. The larvae are solitary defoliators. They overwinter as pupae. Adults either have an extended emergence, or there may be a partial second brood (?).

conservation
No concerns.

diet info
Aspen poplar (Populus tremuloides); elsewhere in Canada mainly aspen but also willow (Salix sp.).

range
Nova Scotia west to central BC, south to New York. In Alberta widespread in the southern Boreal Forest, Aspen Parklands and Foothills.
