what kinda bee is this?

A predatory social wasp of the genera Vespula and Dolichovespula.

It's not a bee; it's a wasp. Bees tend to stay away from other animals unless their hive is threatened because they can only sting ONCE and then they die. Wasps can sting multiple times and are rather aggressive.

Bees are usually hairy or have thicker stripes. They also don't normally act against other species, but are more into plants and pollen.

There's a few different wasp species with a yellow abdomen, including the common wasp, and the german wasp, also known as a yellowjacket

A yeller jacket.
