Dolichovespula? - Dolichovespula arenaria - Female
Perry County, Pennsylvania, USA
Don't know what to think about this one. I originally thought D. arenaria queen... but there were multiple specimins of this wasp going back and forth carrying sugar water back to the nest. I tried to follow them, but they flew very fast, in a straight line, and close to the ground. A queen would not be doing this behavior, so... what species/ caste is this please? Is it just a plain Arial yellowjacket queen?
TAKEN IN EARLY AUGUST a number of years ago..

I'm "unfrassing" these because of the comment by Richard that sheds light on vespid behavior; and because this is a xanthic form of this wasp. We can replace some of these images if better ones come down the pike, but in the meantime, let's save these.

i did not realy know what to do with these since they are not the best. feel free to do with them as you please.

Right guess
This is a Common Aerial Yellowjacket queen (Dolichovespula arenaria).
Nice example of a xanthic individual, with eight "free" spots on urotergites.
Although such feeding behavior, similar to the workers', is rarely witnessed among "fall" queens, it does sometimes occur. For still poorly understood reasons, some young queens in Dolichovespula colonies act as workers, foraging and taking care of the brood, in their mother nest. By doing so, they spend their fat body and are unable to overwinter, doomed to die at the end of the season just like workers. I suspect this was the case of this one individual.

Thank you!
this was a while back, when i first got interested in wasps. really i was just watching them and taking pics... then later when i learned about the different species i would ID the photos. such behavior in this one realy confused me! kinda makes you feel bad for tthe queens that do this... is this behavior only documented in dolichovespula colonies?

To my knowledge, yes
At least this is so far quite unknown in any Vespula species, even in the rufa group. That's not to say it could not exist at all, but in a general way, female castes are less differentiated in Dolichovespula than in Vespula, both morphologically and behaviorally.
