The eggs, which hibernate, are white or greenish white (Scott 1986). The larva is yellowish green with a dark dorsal stripe (Layberry et al. 1998), and pupae are light brown with dark dots (Scott 1986). The adults perch on tall grasses and sedges (males wait for females), and colonies tend to be localized in distribution.
Conservation Not of concern. Diet Info The larvae feed on a number of species of dock (Rumex spp.), and are usually associated with Rumex crispus, and possibly also feed on smartweed (Polygonum coccineum) (Bird et al. 1995). Range Occurs from the southwestern Northwest Territories south to New Mexico and Oklahoma, east to the Atlantic seaboard. Absent from the western Mountains (Opler 1999).
