The St. Andrew’s Cross Spider is easily identified by the white zig-zagged ‘X’, or stabilimentum, in the center of the web. The stabilimenta have been shown to reflect UV light and it is assumed this acts to attract prey while discouraging larger animals from destroying the web. The males lack the bright colourings of the female and are also much smaller, often seen sitting on their own web close by the female. They are non-poisonous but should be handled with care if necessary.
