First instar larvae are pale green, turning yellowish-green with reddish dorsal and lateral stripes in later instars (Bird et al. 1995). Layberry et al. (1998) describe the larvae as bright green with pale dorsal and lateral stripes, and pale oblique bands. The dark brown pupae overwinter (Guppy & Shepard 2001). Adults are never far from larval hostplant patches.
Conservation
