Vespula acadica - female

Vespula acadica - Female
Perry County, Pennsylvania, USA
May 22, 2010
The pattern on this one does not go with vidua (even though vidua may be slightly variable). That means it is either: Vespula acadica, or Vespula austriaca. Both of which are a new species for me and an exciting find.

BTW-What was the habitat where this was found? Was this on a ridge?

She was foraging in some pine trees. The surrounding area is primarily farmland and is surrounded by mountains on all sides in the distance

Moved from Vespula.

Vespula acadica?
I would like to know how this wasp species is V. acadica, since the abdominal patterns are extremely similar to V. austriaca. It is common for the queens and workers of V. acadica to have 2 yellow discal spots formed on each side inside the black regions of the first 2 tergites (sometimes on more or all tergites but it varies) but I think it's abnormal for the yellow discal spots to be this big. Especially in a worker...

V. austriaca is a workerless parasite. It should have long, erect black hairs on the hind tibia, which I see no hint of here. The clypeal teeth on austriaca are very strongly recurved, which I also don't see here.
