St Andrew’s Cross Spider Identification in Australia
Colourful orb-weaver often sitting in an X shape in a web with zig-zag silk bands.
Usually low riskSt Andrew’s cross spiders are distinctive because of their web posture and decorative silk stabilimentum. Look for the spider resting with legs paired in an X, together with bold zig-zag silk bands through a circular orb web. The cross-like silk is a useful confirmation clue, but it may be incomplete or absent from a poor view, so use the web shape, posture and patterned body together. Compare a similar garden orb-weaver or banded garden spider when the web decoration is unclear; these are usually low-risk outdoor web spiders.
