Titan Beetle

The largest beetle by body length in the world. Adults do not feed, surviving on fat reserves from the larval stage. Their mandibles can snap a pencil in half.

💡

Did You Know?

The titan beetle larva has never been found in the wild — scientists only know adults. The larval boreholes in dead trees suggest larvae may grow up to 300 mm long.

Common Bark Louse

A winged bark louse with distinctive cross-shaped wing markings found on tree trunks across Europe. It feeds on algae and lichen on bark.

💡

Did You Know?

Its cross-shaped wing pattern makes it one of the easiest bark lice to identify.
