Rustic Longhorn

A grey-brown cerambycid with wavy pale transverse bands on the elytra, found across Eurasia in birch and poplar forests. It is a common borer of weakened and recently felled broadleaf trees. Adults are diurnal and fast-running.

💡

Did You Know?

Adults are remarkably fast runners and difficult to catch by hand, earning them the nickname 'sprinting longhorns' among collectors.

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.
