This insect was captured in Australia near Canberra. It has a very hard exoskeleton and is over an inch long. It seems to have 6 wings - 2 large pairs and one very small pair. I did not see a stinger - however I have no idea.
I believe this is the Hairy Flower Wasp, Scolia soror. I don't know what you mean when you refer to six wings, however. Like all other wasps, this species has four wings.
