Dotted Bee Fly

A spring-flying bee fly distinguished from its commoner relative by spotted wings and a darker fur coat. Its larvae parasitize mining bee larvae of the genus Andrena.

💡

Did You Know?

It appears only in spring for a few weeks, closely tracking the flight season of its specific Andrena bee hosts.

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.
