Thanks Richard. This is my second Western Y. one in MT and now one in WA and both are chewing on "wood".

A true born Western (Vespula pennsylvanica)
Yellow ring around left compound eye is visible even from this angle. A large-sized worker with some features of a queen, e.g. relatively broad black spots on urosternites. Such "intercaste" individuals can be found late in the season, in nearly all yellowjacket species with the possible exception of V. squamosa..
