Ok, this isn't all that exciting. We already knew she was tameable, but she's level 86 so it's never been possible before MoP. She has a unique look, but only because she's the only boss model wasp with the "SilithidWaspBossSkin2" colour. There are non-boss model wasps that use the skin already (in the same instance). She is incredibly pretty, though. I'll give her that.
She also hurts quite a lot. I took some elixirs and ate haste food just to be safe. Currently you also have to be level 87, as there's a bug preventing you taming stuff of the same level as you.
She was small when first tamed, but upon resummoning she became HUGE. This is a common bug with wasps on the beta currently.
Just to illustrate the difference between the boss and non-boss versions. The boss is the first image. It has a much cuter face, and cooler legs, wings and stinger:
