Been reading wikipedia on yellow jackets, which led to wasps and mud daubers. Most of the yellow jackets I've encountered did not live in the ground, but rather built nests that hung on eaves and even gates or corners of buildings. They are not social, but rather tend to be solitary, they are very aggressive and will sting multiple times without provocation. Unlike bees who die when they sting, the stinger does not come off the insect. The sting is significantly mre painful than that of a bee. They build small nests like what I see described for paper wasps, but do not live in them, only lay their eggs there. They are larger than bees, generally close to an inch long, and are predominantly yellow. So, none of this really matches what is said here or in wikipedia, but is all based upon my real-life experience. So...what are my yellow jackets?
