Leaf-curling Spider 
Phonognatha graeffei

These spiders cleverly weave a leaf or other object into the centre of their webs as a hide-away from birds and other predators. Leaves are curled to form a funnel that the spider can hide inside. They have also been seen to use old snail shells are discarded pieces of paper. This species is unusual among orb-weaving spiders because males cohabit in the leaf retreat with both immature and mature females, mating with the former shortly after the female molts. Cohabitation appears to be a form of mate-guarding.
