White-faced hornets[0] are a lot more painful than yellowjackets[1] (they are about twice as big, but pretty much the same configuration). I don't think yellowjackets will swarm, if a forager gets killed. Don't step on one of their nests, though (they dig holes). Also have a friend who did that, once. Also, if you get close to one of their nests (hard to see), they might swarm you. The biggest difference, is that yellowjackets are much more aggressive foragers, so it's easy to piss off individuals. I had [yet another] friend that imbibed one that went into his can of soda. He tells me the experience left his lip swollen like a cartoon, for several days.

Neither bees nor wasps will swarm if far from their nests mainly because there won't be many as they forage in a solitary manner. But when hornets attack as a group, then they swarm, and they use their pheromones to aid in swarming.

We have yellow jackets in the SE US. They are as persistent as they are aggressive. The "yellow jacket in the Coke can" is almost a cliche it happens so often. I once ran over a nest with a lawn mower at my family's lake house. I don't specifically remember being suddenly covered in stinging yellow jackets (I was), but I do remember vividly that was the fastest I'd swum across the lake.
