The Glasswinged Butterfly (Greta oto) are one of the most spectacular species of butterflies on the planet. This isn’t because of its bright coloration or unique shape, however, but rather its wings which are almost completely transparent!
Most butterflies have very tiny scales which cover the wing membranes. These scales are what give monarch butterflies their orange and black hues or morpho butterflies their vivid blue coloring. Unlike these butterflies, between the veins of the Glasswinged Butterfly there are no scales – just translucent membranes – which means the wings allow you to look straight through them! That’s why the Spanish name for these butterflies is ‘espejitos’ which literally translates to ‘little mirrors.’
