Wingspan 3.9 cm. Forewing is a pale red-brown with two jagged median lines, a small pale discal spot, and prominent orange dashes in the submarginal area of the wings. This geometrid is common and widely distributed in western North America. Moths fly in midsummer. Caterpillars feed on the foliage of conifers, especially Douglas-fir (Pseudotsuga menziesii) in its western range and pines (Pinus) east of the Cascade Mountains.
