Australia has some very large huntsman spiders but they are no match for these wasps. About 45mm long overall we first saw one fly past us two years ago and today we were lucky enough to see one land. The antennae are always busy, strong and flexible and, combined with large rear tarsal spines, enable the wasp to subdue large sparassids.
Like last time we saw one it buried itself deep into the blades of gahnia (a clumping sword grass). Luck I have a very small pocket camera because this was a very tight location. This is in a local nature reserve. (Kings Park)
Lifer! These wasps front up to a huntsman face to face and curve the abdomen forwards to sting and paralyse the spider. It is then taken to a prepared hole in the ground and an egg is added and buried. That must make a fine feast for a baby wasp.
I also wonder if there is any Batesian mimicry going on with a very large fly we found in the same area two years ago. See here http://www.projectnoah.org/spottings/160...
