Beetle Larva Moving and Feeding Inside a Log

Many species of beetle live inside live and decaying trees, branches and logs when they are in larval form. It is possible to detect the sounds with a contact microphone. The sounds tend to be either very short clicks caused by feeding or more noise-like due to movement. The recording here is of the larva of a Two-banded Longhorn Beetle (Rhagium bifasciatum) inside a pine log. Both types of sound can be heard.

Wasps and hornets, for their stings, a shame as they are useful predators of damaging insects in horticulture.
