Phonognatha graeffei, referred to as the leaf curling spider, is a common Australian spider found in woodlands and urban areas in the northeastern, eastern and southern states. A member of the family Araneidae, the orb-weavers, it was previously placed in Tetragnathidae.
The spider is distinguished by having a curled leaf at the centre of its web, in which it shelters. The species form pairs living together in the same leaf, though at opposite ends of their shelter, even before mating at maturity. The female creates a separate curled leaf "nursery" hung in foliage nearby.
