Green Frogs breed in semi-permanent or permanent freshwater ponds (Wikipedia 2009). BC Frogwatch (BC Ministry of Environment 2009) describes reproduction in Green Frogs as follows: ' females lay eggs in a single layered mass on the water's surface, about 15 to 30 cm across. Each egg mass may contain up to 5000 eggs. Tadpoles hatch out within a few days, depending on water temperature, and develop over the course of the summer; juvenile frogs emerge in late summer if the eggs are laid early in the season, or the tadpoles from later egg masses may overwinter in larval form. Green Frog tadpoles in B.C. probably overwinter as tadpoles, but this has not been studied. Green Frogs reach sexual maturity two to three years after metamorphosis. Their lifespan in the wild is unknown, but Green Frogs in captivity have lived up to ten years.'
| Tadpols are indiscriminate feeders (Jennssen 1967). They will attempt to eat any mouth-sized animal they can capture, including insects, spiders, fish, crayfish, shrimp, other frogs, tadpoles, small snakes, birds, and snails. Tadpoles graze on algae and water plants. Although Bullfrogs include juvenile frogs in their diet, juvenile frogs are not an important component of the diet of Green Frogs (Werner et al. 1995).
