Glasswing Butterfly
Remarkable for its transparent wings, created by nanopillar structures that reduce light reflection to just 2%. This makes it nearly invisible in flight through the rainforest.
Did You Know?
The glasswing butterflys transparent wings have anti-reflective nanopillars that inspired researchers to develop better anti-glare coatings for smartphone screens.
Lapland Ringlet
A dark brown butterfly with prominent yellow-ringed black eyespots on both wings. The flight is slow and bobbing close to the ground. It inhabits wet boggy areas in the boreal and subarctic zones.
