I thought it was a hornet as its just over a inch long but of course I can't measure it! It's also got a orange/ red tinge to legs and wings but not on the head or body. Wrong type of spots on the back too to be a hornet? Can't belive I was ever offered a job as an entomologist! Google says common wasp but it's too big, too orangey. The markings look perfect apart from that is it really a huge wasp?
