Identification

This is a mid-sized owlet moth. Adults are 11 16 to 1 in length.

The forewing is bright yellow or pale yellow with pale brown scalloped lines; dark brown spots (reniform, orbicular, and claviform spots); a toothed, chocolate brown postmedial line; and a band of dark brown shading beyond that. The spots are said to be “outlined in brown”, but appear to be mostly outline. The reniform spot in the median area is narrowed in the middle appearing as two connected spots. The wing tip (apical area) is yellow. The hindwings are white.

The antennae are slender and thread-like.

Larval Food

Eastern bottlebrush (Elymus hystrix) grass is the normal foodplant for early and middle instar larvae. However, the stalks are not thick enough to support older caterpillars, which move to may-apple (Podophyllum peltatum), lilies (Lilium sp.), dark green bulrush (Scirpus atrovirens).

 
Adult Food

 

 
Life Cycle

The eggs are laid in the fall and hatch in the spring. The larvae pupate in the summer and emerge as adults in late summer.

 
Behavior

Middle and late instar caterpillars bore into the roots, rhizomes, and stems of host plants.

Adults are sluggish, which may account in part for the scarcity of this species. They are active at night and are attracted to light.

The wings are folded over the body when at rest.
