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.

Adults are remarkably fast runners and difficult to catch by hand, earning them the nickname 'sprinting longhorns' among collectors.
Amazonian Scarab
A strikingly colorful dung beetle with metallic green, copper, and blue hues. Males have a prominent curved horn on the pronotum.
Did You Know?
It can bury a dung ball many times its own weight in under an hour, recycling nutrients back into the forest soil.
