Female grows to around 14mm, male up to 9mm
Found mostly under the bark of dead trees. Sometimes shows up inside houses.
The Walnut Orb-weaver is a fairly common garden spider. It is dark coloured, with a shiny, pill-shaped abdomen. The female Walnut Orb-weaver has a larger, more rounded abdomen. The male is slimmer and has distinctive rounded palps. Both the male and female have a brown, oak leaf shaped marking on the abdomen.
