Wing span: 1 - 1 3/8 inches (2.4 - 3.5 cm).

Life history: Males perch on vegetation within 2 feet of the ground to watch for females, usually in the early morning. Females lay eggs singly on or near the host plants.

Caterpillar hosts: Paspalum and St. Augustine grass (Stenotaphrum secundatum).

Adult food: Nectar from flowers including pickerelweed, selfheal, and sweet pepperbush.
