Description: Unexpected Cycnia Moth is a medium-sized (28 to 36mm) moth that has a mostly yellow head and abdomen, with dorsal lateral rows of black spots on the abdomen. The thorax and wings are whitish to gray, with a yellow border along the basal half of the costa of the forewing. The underside of the forewing has gray shading, but is not conspicuous.

Similar species: The Delicate Cycnia (Cycnia tenera) is similar, but has a longer yellow border along the costa of the forewing, and the shading on the underside of the forewing is more conspicuous.

North American Range: This moth ranges from New Jersey south to Florida and west to Texas and South Dakota. In Virginia, it has been documented in Nottoway and Dinwiddie counties.

Flight season and broods: They fly in spring and late summer. Two or three broods are produced each year.

Habitat and Food Plants: The habitat is typically barrens and associated dry grasslands. Milkweeds are the food plant.

Behavior and Ecology: The pupae mature fairly quickly allowing the second brood of adults to appear in August. This moth is typically found in high quality, coastal scrub, dry barrens and similar native grasslands typically on sand and associated with the Atlantic Coastal Plain or Great Lakes drainage.

Population trend and potential threats: Much of this species habitat is fragmented resulting in widely separated occurrences. Because this moth overwinters aboveground in a cocoon in the leaflitter, fire is a potential threat.

Management practices: Efforts must be made to secure unburned refugia containing known moth and milkweed populations during prescribed fire management operations. Protection and restoration of these ecosystems will hopefully provide additional habitat for this species.
