longhorn beetle

Beetle with extremely long antennae, usually equalling the length of the entire body, and often twice its length. Their bodies are 2–150 mm/0.1–6 in long, usually cylindrical, and often mimic wasps, moss, or lichens. The larvae, white or yellow grubs, are wood-borers, mostly attacking decaying or dead wood, but they may bore into healthy trees causing much damage.
