"Sunset moths" originated in Madagascar, and the bright colors on their wings are also used to warn predators of their toxicity. Butterflies and moths belong to LEPIDOPTERA, and there are many scales on their wings.
Their wings are made up of tiny spots-providing moisture protection for insects and forming elegant color patterns. Some colors are caused by pigments in scales, but rainbow-like tones are caused by the scattering of tiny scales.
