Hi, my mum had a bug/fly land on her and swatted it. It died but is dark in colour but when the photo is taken with flash has amazing colours and a very big sting, similar to a bee but much bigger and with barbs on it.
Though it appears to be a stinger, the Cuckoo Wasp is incapable of stinging. The female uses her stinger-like ovipositor to lay eggs and according to the Brisbane Insect site: “Most species are external parasites of other wasp larvae. Females lay eggs in nest of other wasps (Eumeninae of Vespidae and Sphecidae) while the nest host collect food for larvae. Cuckoo Wasp larvae hatch and feed on the food or the host larvae.”
