Wingspan 2.8 cm. Forewing with a black median band that has a smooth rounded outer margin, postmedian line has sharp dentate spots. This geometrid is common and widely distributed in western North America. Moths fly in midsummer. Caterpillars feed on the foliage of herbaceous plants, especially fireweed (Epilobium).
Similar species: species of Eustroma, such as Eustroma semiatrata, have a jagged outer margin on the median band; species of Eulithis, such as Eulithis propulsata and Eulithis xylina, are larger.
