Description of specimen

Large brown flying beetle about two inches long with long curled antenna.


This looks to be the Ponderous borer, one of Oregon's largest insects, and the inspiration to the modern cutting tooth on a chainsaw. It is not a pest but aids in "turning over" dead trees, logs, etc.,a%20long-horned%20beetle%20%28named%20for%20the%20long%20antennae%29.
