V. pensylvanica?
I'm not convinced that this is not a Vespula pensylvanica male. We might even have more than one specimen here?

There are exceptions among males....
And even among workers in some Northern populations of the species. I agree with Eric this one is a (dark) Vespula pensylvanica male.
First, rounded shape of pronotum does not fit with Dolichovespula: anterior keel is missing.
Second, flattened shape of the last urotergite is typical of males of the vulgaris group of Vespula (the Paravespula genus of old European litterature).
I admit that color pattern of this specimen is quite misleading, being virtually identical to an "average" D. arenaria. But these two distantly related species form a "muellerian" group, i.e. they mimick each other.
