💡

Did You Know?

Isolated populations on different Japanese islands have diverged into distinct colour forms, making them popular among collectors.

Alpine Longhorn Beetle

A strikingly beautiful blue-grey beetle with black spots, listed on multiple European conservation directives. Depends on old-growth beech forests with standing dead wood.
