Norfolk Hawkers and Swallowtails + a waspbee to id

Just had a Norfolk Hawker in the 'garden' a nice surprise and slightly unexpected seeing as there is no water very close by. Had a day off yesterday in which I did my volunteer farmland bird survey at a farm on the river Ant, a good survey, nothing unexpected but nice to go somewhere different. On the way home I stopped off at a private site to have a look at some dragonflies and anything else that appeared.

The day list included all the regularly seen odes, firsts for the year for me included Norfolk Hawker and a few Emperors, there were stacks of Hairy, Red eyed, Variable, Blue tailed and Azure Damselflies, they seemed to be absolutely everywhere as well as 4 spotted chasers.

Finally can anyone ID this Wasp, or is it some sort of nomad bee? It was on the Fen S of the river and looks like it could be interesting, well it could be.

EDIT: It is Argogorytes mystaceus
