The Beautiful Glass Butterfly

This magical butterfly, officially named 'Greta oto' but more widely known as the 'glass butterfly' boasts incredibly beautiful, transparent, wings. A closer look at the wings reveals veins running across them, but you can see right through them, as if you were looking through a window.

Most butterflies come with painted wings and spectacular patterning that we humans love to see. This patterning has two primary roles. It both deters predators and attracts potential mates. A glass butterfly's wings also help protect it from other animals because they allow it to camouflage against background foliage and therefore avoid detection by birds species with excellent eyesight, particularly good at detecting color.

To achieve this kind of transparency, the wing is coated with numerous sub-microscopic tiny bumps that break light and prevent it from bouncing back from the wing. Eyes perceive color based on the way it reflects light, so this special trait renders the wings largely translucent.

Wide Range: Although primarily found in Central and South America, from Mexico through Panama and down into Colombia and Ecuador, glasswing butterflies are known to migrate considerable distances. They have been spotted as far north as Florida and as far south as Chile.

Adult glasswing butterflies feed on nectar from a variety of flowers, with a preference for those that are typically ignored by other species. This diet not only sustains them but also makes them important pollinators within their ecosystems. Interestingly, the caterpillars of the glasswing butterfly feed on toxic plants, which makes them unpalatable to predators.

The males of the species engage in a unique behavior known as "leking," where they gather to compete for female attention. The males display their vigor and attractiveness by fluttering their wings rapidly to demonstrate their strength and stamina, a key factor in attracting a mate.

Currently, the glasswing butterfly is not listed as endangered. However, like many species, it faces threats from habitat destruction and climate change, which could impact its populations in the future.
