A large grey-yellow lamiin covered in dense ochre pubescence, found across Eurasia in poplar-dominated habitats. It is a significant pest of poplar plantations, with larvae boring into the lower trunk. Adults are nocturnal.

💡

Did You Know?

Heavy infestations at the base of poplar trunks can cause them to snap in windstorms.

Bornean Flat Stag Beetle

A medium-sized, very flat stag beetle with a glossy dark reddish-brown body perfectly adapted for living in thin spaces under bark. The mandibles are short but wide and strongly toothed.

💡

Did You Know?

Its body is so flat that it can fit into gaps as thin as a few millimeters, making it nearly impossible for predators to extract.
