Rough-Skinned Diving Beetle
A large diving beetle of northern and alpine regions across Europe and Asia. Both sexes have finely sculptured elytra, distinguishing it from the great diving beetle.

It is one of the few large predatory beetles adapted to survive the extreme cold of subarctic lakes.
Sumatran Flat-faced Longhorn
A very large longhorn beetle with grey-brown mottled elytra and exceptionally long antennae. The flat face and powerful mandibles help it strip bark from living trees.
