During the hottest, driest times of summer, chorus frogs and spring peepers may hide under leaf litter, spend their time in trees, or even bury themselves in the top of soil to stay cool and moist. They are most active and noticeable in early morning. But once they stop singing, they're hard to notice unless you're very patient and observant. The little tadpoles are growing; it takes about 3 months for chorus frog and spring peeper tadpoles to mature into frogs.
