Gray spherical cocoon, located in back of attic above garage - Vespula

Gray spherical cocoon, located in back of attic above garage - Vespula
Hudson, Summit County, Ohio, USA
June 15, 2014
Size: 2-3 inches diameter
I just noticed this cocoon (or egg sac?) hanging from a rafter in the garage, right next to where the chimney comes through. It's way in the back so it's tough to get a better shot than this, but it's roughly spherical, gray, and approx 2-3 inches in diameter (you can see a brick right behind it). I can't tell how solid it is or what the texture might be. The last time I was back in that corner was a year ago and I didn't notice it then. Didn't see any movement or anything else near it. I searched online for "gray sphere cocoon" and the like, but couldn't identify it. I'm curious if anyone knows what it might be.

Yellowjacket nest?
Looks like a gray yellowjacket nest to me

Wow, yeah that definitely could be it.
I didn't see anything crawling in or around it to confirm (maybe it's abandoned, not sure - I don't think it was there last summer, but it's in a pretty awkward, tucked-away location), but after doing an image search for "yellowjacket nest" on Google, that seems to be right on. Some of those images look really close to the image I posted. Thanks for helping me identify it! I know the image I posted wasn't great - hard to get good enough lighting in the attic to take a decent picture. Thank you.

Although I wish they wouldn't create a nest in my house, it's pretty amazing how they manage to build it up and attach it to the rafter like that.

 
A vespula nest but which species?
It could either be of V. germanica or a vespula rufa species member, but without a wasp it is almost impossible to tell which species built the nest as the above listed wasps all have a uniform nest design.
