As the snow melts and the soil thaws and softens, frogs start emerging in the north. In the south, they emerge with spring rains. Frogs feed on aquatic insects, tiny fishes, and other little animals. Spring peepers and chorus frogs are almost immediately in breeding readiness when they emerge in spring, and males can often be heard singing while there is still some snow and ice on the ground. Females are attracted by their sound, and soon lay their eggs.

Eggs can hatch fairly quickly--tadpoles are not completely developed when they first hatch. At first the tadpole uses its mouth or a tiny sucker to hold onto a plant or other support in the water, but soon starts to swim. It only takes a few weeks for peepers and chorus frog tadpoles to develop into frogs.
