Methona themisto, the themisto amberwing, is a butterfly in the Nymphalidae family. It is found in Brazil and Panama, mainly in forests, and is relatively common. It has a wingspan of about 8–10 cm. The upperside of the wings is pale yellow with black veins, black margins, and black cross-bars on the forewings. The hindwings are very round, and the edges on the upperside of the hindwings and the tip of the forewings have small white-blue spots. The antennae are black with a yellow tip.

Adult butterflies drink nectar from flowers. Caterpillars feed on plants in the Solanaceae family, mainly Brunfelsia pilosa and Brunfelsia uniflora. Females lay white eggs on the underside of fresh leaves. Caterpillars are black with 12 yellow rings and take about 30 days to reach the final stage. The pupa is pale yellow with black markings.
