Not just a conspecific, a nestmate, and to be entirely clear that's known in polistid wasps [0] but not, so far as I'm yet aware, in vespids, which are understood primarily to use scent cues instead. That said, with regard to V. mandarinia it's not easy to be familiar with current research unless you read Japanese, which I don't; probably in a decade or so there will be a great deal more in the way of English literature, given the rate at which I expect they will establish across at least the western half of the continent. Maybe a decade after that we'll have a reasonable depth of English-language papers that have to do with something other than unsuccessful extirpation strategies; I expect it depends first on how quickly they find a way across the Rockies, and second on whether anyone actually cares to fund entomology departments for something other than bee husbandry and "pest" management.
In any case, if you're attempting to make an argument here, its thesis could stand considerable clarification. I'm not even sure whether you're intending to agree or not with my own argument, so would you like to elucidate a bit on what point you're trying to make and how you support it?
