Giant Pill Millipede
A large pill millipede that can roll into a perfect sphere the size of a golf ball when threatened. The body is dark brown to black with smooth, overlapping plates.
Did You Know?
When rolled into a ball, the armor plates lock together so tightly that most predators cannot pry them apart.
Large Poplar Longhorn
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.
