Fun facts
The male digs a little room under the bark, and up to four females come to visit him.
Each mother digs her own tunnel and lays about 80 eggs, each in its own tiny nook along the sides.
The beetles send out a special smell that calls many more beetles to the same tree.
Woodpeckers help the forest by splitting off the bark to eat the larvae.
Its wing cases have four little spines at the end of each side, which is why it is also called the eight-toothed bark beetle.
