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.
Blue Death-feigning Beetle
A rounded blue-grey desert beetle covered in a waxy powder-blue coating. When threatened it flips onto its back and plays dead with legs extended stiffly.
Did You Know?
Its death-feigning behavior is so convincing that predators lose interest and the beetle can remain motionless for hours.
