The antennae can be up to twice as long as the rest of the body in males, and the same length in females.

The elytra are flat, blue-gray, with variable black spots, including a prominent one on the thorax, a silky one in front, and a small one in back.

The coloration serves as good camouflage with their preferred habitat, the European Beech.

Its numbers across Europe has greatly depleted in recent years, and it is a protected species in Germany, Hungary, Italy, Poland and Slovakia.

After mating, the female lays the eggs within a crack in the bark of beech trees.
