Insect ID ?

[SmartWombat]

Irridescent blue sheen to the wings, black body, strong fast flier.
Any ideas?

Hard for me to tell for sure, but I think that's the same as these guys?






Commonly we call these guys black hornets, but they're not a hornet. I believe they're great black wasps.

Paul,

Just looked through my pocket Nature Insect book and it could be Spider-hunting wasp (Pompilius cinerus) buries eggs in sand if that helps.
