Green frogs breed in semi-permanent or permanent freshwater. Males call from and defend territories. The distinctive call sounds like a plucked banjo string, usually given as a single note, but sometimes repeated.The breeding season is from April to August.Actual mating involves amplexus, whereby the male grasps the female with his forelimbs posterior to her forelimbs. The female releases her eggs and the male simultaneously releases sperm which swim to the egg mass. Fertilization takes place in the water. A single egg clutch may consist of 1000 to 7000 eggs, which may be attached to submerged vegetation.Green frog tadpoles are olive green and iridescent creamy-white below. Metamorphosis can occur within the same breeding  season or tadpoles may overwinter to metamorphose the next summer. Males become sexually mature at 1 year, females may mature in either 2 or 3 years.
