Only in Australia.

A giant wasp has been caught on camera carrying its paralysed prey up a wall - and the prey just happens to be a massive huntsman spider.

The incredible photo of the insects was captured at a house in Sydney's suburb of Bronte and shared online on Thursday.

Experts say the orange-brown spider wasp was simply "going off to do her stuff".

Its "stuff" is both intriguing and somewhat confronting.

Nature in action

The insect is a Cryptocheilus bicolor, a strikingly coloured spider wasp native to Australia, according to Dr Dieter Hochuli, Associate Professor at The University of Sydney's School of Life and Environmental Science.

It's a natural predator of the huntsman, paralysing them by stinging their undersides.

The wasp then burrows into the spider to lay eggs, which hatch and feed on the prey.

'Brutal but impressive'

Although the wasp is relatively docile, it packs a punch if provoked.

"I went for a walk this morning and I saw quite a few of them. They are really active this time of year," Hochuli told 7NEWS.com.au.

"They are quite extraordinary animals, their lifestyle is a little bit brutal but they are very impressive to see live."

But what should you do if you stumble across one?

"Apparently their stings are very painful so it is best to let them get on with their lives," Hochuli said.
