Green Tree Frog.

…

…Eggs are laid under water surface and are attached to roots of floating vegetation. Embryos hatch in a few days and tadpoles transform in two months. Juveniles often feed on insects in nearby fields in late summer and autumn. Notes: Green tree frogs can change between dark and light green depending on temperature and lighting. They perch by day on upright cattail or other plant (including trees!) while their legs are tightly tucked under body.
