One of the most abundant frogs in the state. Relatively tolerant of open, sparsely vegetated sites. Spends most of their time around water’s edge. Dispersal to new habitat is not uncommon – usually a large group of juveniles will migrate together. Over-winter in water, shallowly buried in mud or debris. Typically dormant from early November to early April, but some may be active on sunny days even in mid-winter. Call Low twang like a loose banjo string, “c’tung,” given during the day. Breeding Begin calling in early to mid-May and continues possibly into August. 1,000-5,000 eggs laid attached to emergent or surface vegetation. Development Eggs hatch in 3-5 days. Some tadpoles transform in late summer, but many over-winter as tadpoles and transform during second summer. Reach maturity in two to three summers. Habitat Type Ephemeral wetlands. Permanent wetlands. Forests. To a lesser extent, they may be found in agricultural areas.
