Old joke from Public School days:

Kid #1: Hey! What is dark green, has enormous eyes, 6 long legs, red spots, sharp pointed teeth, and is about 2 inches long?

Kid #2: Hmmm... I have no idea. Why do you ask?

Kid #1: Because there's one crawling up your back!!

2 x the size of a wasp

That is a European Hornet - you can read more about them here:
