Description

In adult pearl crescents, the wing pattern varies, but all have orange wings with black borders with fine black markings. The common name comes from a crescent-shaped, light-colored spot surrounded by a darker patch on the outer edge of the hindwing, viewed from below. The first pair of legs are short, hairy-looking, and useless for walking.

Larvae are brownish-black with light dots, yellow lateral stripes, and yellowish-brown spines. The head is black with a pale spot in front.

Size

Wingspan: 1–1½ inches.

Distribution in Missouri

Statewide.

Status

Abundant breeding resident.

Life cycle

Adults fly from early April through November. Eggs are laid in clusters of up to 200 under the leaves of the food plant. Larvae that occur in late season hibernate.

Human connections

In addition to their considerable aesthetic value, butterflies pollinate plants, many of which have commercial importance. Additionally, because butterflies are sensitive to toxins and disturbance, they are good indicators of the overall status of ecosystems.

Ecosystem connections

The caterpillars are herbivores that graze on vegetation. The adults serve a role in pollination. All stages provide food for predators.
