One of the 260 species of Orb-weavers in Australia. “This species is extremely variable in colour and pattern. They feed on a wide range of flying insects at night and often after eating the web at dawn, retreat to foliage at the edge of the web. Bites are rare, causing only temporary symptoms and mild pain”. They are not an aggressive spider and found in many varieties from the open woodlands to creek surrounds on the wildlife refuge.
