Biology

Parawaixia dehaani is nocturnal and feeds mainly on moths. During the day the spider shelters under a leaf in the vegetation.[2] It builds a vertical orb web with an open hub, which often looks damaged, with sections missing, hence the Australian common name, abandoned-web orb-weaver.[4] When disturbed the spiders falls to the ground and plays dead with its legs retracted.[4] Bats have been recorded as being captured by this spider.[6]
