Graceful Tree Frogs in ‘amplexus’. The male grasps the female and fertilises the eggs she lays. The frogs lay a single layer mass or small clump of eggs just below the surface of water, and sometimes the eggs are attached to floating vegetation. They will lay eggs in temporarily flooded areas, and even in buckets or swimming pools. Photo taken at Boondall wetlands, Brisbane, by Mike Peisley.
