This nest underneath my pool in Massachusetts doesn't look like the yellow jacket nests I usually see which are flimsy and honeycomb-like with only maybe ten or so insects on them. Those nests are oftentimes in shutters or hanging on my garage door. This nest was much bigger, sturdier, had an actual inside to it, and the yellowjackets themselves seem a bit smaller and more "bee" like. It also was more menacing in its overall feel.

What do I have here? And what are the other more common yellowjackets that I described?

Thanks!
