Other behaviours and adaptations

The Comb-footed Platform Spider is not as specialised a retreat builder as the leaf-curling orb weavers; however a curled leaf may be used, or some leaf detritus may be loosely silked together. The retreat is placed in the centre of a network of threads spun above a horizontal, close-meshed silk sheet. These webs are usually built among understorey shrubs and low trees and are often seen in overgrown gardens.

Life history mode

Mating and reproduction

The egg sacs are placed inside the Comb-footed Platform Spiders' silk retreat.

Predators, Parasites and Diseases

The complex webs of the Comb-footed Platform Spider harbour a range of other animals, from small moth larvae that scavenge along the silk lines to spiders that find prey in the outer parts of the web. Some of these are small prey stealers of the genus Argyrodes. However, they include one species that is a specialist predator on A. mundula. Argyrodes incursus is a small, jet black spider with a single red spot on its abdomen. Somehow, the smaller spider kills the larger A. mundula and eats it, finally making its own egg sac within the dead host's retreat.
