The green frog is a large frog. Adults can have a body as long as 100 mm. Females are usually bigger than the males. Males have an ear drum that is larger than their eye. They are green to greenish brown on top with a few small black spots. There are dark or black stripes on the legs. Around the mouth the colour is usually bright green. The belly is white.

Look-alikes: The mink frog and the leopard frog can look like a green frog. A mink frog has no stripes on its legs and has many dark blotches. Leopard frogs have large black spots all over.


The green frog is usually green in colour. It is a very common frog in eastern North America, but there doesn't seem to be any special reason why it is called the green frog.


The green frog is usually found near water, along lakes, ponds, streams or in other wetlands. This frog lives in eastern central North America. It is only found in the southeast corner of Manitoba.

The green frog spends most of its time in or near the water. It is most active at night and hides near water plants or along the water edge by day. They don't go far from water. Green frogs spend winter on the bottom of ponds, streams or lakes.


Green frogs eat many kinds of insects and other small animals without backbones like snails and spiders.

Green frogs are eaten by reptiles like the snapping turtle and the red-sided garter snake, and by wading birds like the great blue heron.


Green frogs mate from June to mid-August. They breed in large ponds or along the edges of small lakes. Male green frogs stay in their own small area. They do not bunch up to call for mates like most frogs.

Mating call of the green frog:

A calling green frog .

Females lay as many as 4000 eggs in one large bunch on plants at the top of the water. The tadpoles hatch out in about 7 days, but will not change into froglets until the next summer. It takes more than a year (nearly 400 days) for a green frog egg to become a froglet. The new froglets are large. They can be as big as 40 to 50 mm long.


There can be more than 50 green frogs in one hectare along the edge of a pond or lake.


The green frog has a mating call that sounds like a broken banjo string:"clung!"


Green frogs aren't very common in Manitoba and probably aren't used by people.
