Moved from Dolichovespula.

Moved from Rocky Mountain Aerial Yellowjacket.
I'll leave it here at genus until we're sure where this belongs.

I agree
This spring queen gatherin wood pulp is actually a D. norvegicoides.

 
Thanks
for the definitive identification.

Locality
rules out several species, but still quite a few reach this part of Canada (a.k.a. Alaska). Not really enough detail in the photo for a 100% identification but my best guess is Norwegian Yellowjacket - Dolichovespula norvegicoides.

This is a queen of Dolichovespula Alpicola Eck
Great find

 
Identification?
Sorry, but your user page is blank, so we don't know your credentials or experience level. Why is this alpicola and not norvegicoides?

 
Dolichovespula Alpicola
The The thoractic spots usually are a dead givaway to seperate these two species, (as will be show in the photos attached). As far as my credentials go, I am a self taught entomologist who has been studying the Genus Vespinae for the past 10 years. I am also planning on writing a monograph to all the species of Yellowjacket on a worldwide basis. This monograph will include keys to the species, A taxonomic review, As well as discriptions, An account of nesting biology and distribution of each species, Followed by a complete checklist of the world species. Diagnotic examples: Note the Thoratic markings on this worker of D.Alpicola:

In comparison to this worker of Dolichovespula Norvegicoides:

Clarify please
I'm not certain which markings you are referring to. What is the difference between the two species? Color markings are notoriously variable.

 
sorry for the late response
2 very small mesoplural spots are generally a good indicator as well as the widening and the yellowing of gasteral tergites 2-5. Free discal black spots on the fifth and sixth terga are also good indicaters of D.Alpicola. This specimen is more xanthic however and lacks these free spots. I am going to post some pictures of D.alpicola and D.norvegicoides
which were photographed by Bob Jacobson the author of Vespula Flavopilosa. Here is a link to other specimens of D.Alpicola with the same small mesupular spots you can use for comparison:
