Madagascan Sunset Moth

From The Department of Peculiar Specimens

The Madagascan Sunset Moth (Chrysiridia rhipheus) is native to the island of Madagascar, where it inhabits forests and open woodland. Unlike most moths, it is active during the day and is famous for its dazzling wings, which shimmer with bands of green, blue, red, and orange. The colour is produced not by pigments but by scattering and interference of light by the microstructure of ribbon-like scales across the wings.
Its caterpillars feed exclusively on plants of the Omphalea genus, absorbing toxins that make both the caterpillar and the adult moth unpalatable to predators.
