Habitat and Biology
This spider has been described as the master of camouflage, its colour pattern resembling a bird dropping. Another common name for the species is the death's head spider, due to the supposed resemblance of the body colours to a skull. The bird-dropping spider is a sedentary spider found sitting on a leaf or suspended underneath its egg cases. The egg cases, numbering up to 13, are large (12-14 mm in diameter), dark brown spheres with black criss-cross markings.
This spider feeds at night, almost exclusively on male moths. It sits with forelegs outstretched awaiting the approach of prey. The spider attracts the moth by releasing a sex pheromone or smell similar to that produced by female moths.
