Argiope aetherea is a common, large orb-web spider This species is commonly known as the St Andrew's Cross spider due to the characteristic cross-shaped web decorations often included in their webs by female spiders. A. aetherea is similar in appearance to A. keyserlingi, however female A. aetherea are generally larger than A. keyserlingi. Like most orb-web spiders, A. aetherea shows considerable sexual size dimorphism, with females being many times larger than males.


The species is commonly found along the east coast of Australia, in particular Queensland, New South Wales, and Victoria.[1] It also appears in China.


There exists a subspecies from New Guinea:

  • Argiope aetherea annulipes Thorell, 1881
