Biology

The St Andrew's Cross spider commonly builds its web amongst shrubs and other vegetation or against walls of buildings. It normally hangs upside down in the web with two paired legs placed along each arm of the cross. The silken cross may be used for strengthening the web, for camouflage or for enhancing prey catches. It has been shown that the cross reflects ultra-violet light which is particularly attractive to insects. Egg sacs are pear-shaped, green in colour and are suspended in nearby vegetation rather than in the web itself.

Distribution

Eastern mainland Australia.

Habitat

Woodlands, heathlands, dry sclerophyll forests and urban gardens.
