Biodiversity appreciation post of the day: the Glasswing butterfly!
Yes, they're not fiction. Their real name is Greta oto, and they're also referred to as espejitos ("little mirrors"). They're found in central and north regions of South America.
About the wings, from wikia:
"The transparency of Greta oto’s wings results from the combination of several properties: wing material has a low absorption of visible light, there is low scattering of the light that passes through the wings, and there is low reflection of the light impinging on the wing's surface. The latter occurs for a broad range of incident wavelengths, covering the entire visible spectrum, and all incidence angles."
