Macromoths of Northwest Forests and Woodlands

Egira rubrica [Noctuidae]

JPG-Egira rubrica

Wingspan 3.4 cm. Forewing is brown to pale yellow, often with a black subapical band; hindwing is white. This noctuid is abundant and widely distributed in wet conifer forests west of the Cascade Mountains but more restricted to riparian forests at low elevations east of the Cascade Mountains. Moths fly in early spring. Caterpillars feed on the foliage of ocean spray (Holodiscus discolor), deerbrush (Ceanothus integerrimus), and snowbrush (Ceanothus velutinus).

Similar species: Egira perlubens forewing is dark gray to black with a pale orbicular spot, widely distributed in western North America.
