• thanks for such a quick reply, Dave. Are they common? I live in Ku-ring-gai but as I said, haven't seen them before. I did notice a sting appear as I was trying to take the photo :-)
• I have never seen this wasp/fly before, it was in my house today. About the size and shape of a german wasp, but a little slimmer, it was matt black with regular white? spots on its body and legs. Sorry the image is so fuzzy, it was in a perspex chamber being expelled!
