Frogs and Toads
Blanchard's Cricket Frog
2 to 2.5 inches long; dark mask through its eye and a white stripe on the upper lip.
Fairly common in wooded habitats.
Adults are rarely found in water except during breeding.
Will migrate across open areas to reach suitable breeding ponds, but otherwise remain under tree canopy.
Hibernate on land beneath loose soil, leaf litter, or decaying logs. Survive periods of sub-freezing temperatures by producing large amounts of glucose, causing ice to form in the extra-cellular spaces rather than within the body cells.
Tadpoles approaching metamorphosis develop poison glands to repel aquatic insect predators, although biggest threat to tadpoles is ponds drying before transformation is complete.
Adults have toxic skin secretions, which repel shrews, but not snakes, other amphibians or birds.
Squawking, duck-like call.
Vernal ponds, floodings, wooded swamps, and backwaters are used for breeding.
Breeding season is usually only 1-2 weeks long, in mid to late March or early April.
Females deposit from 500 to over 3000 eggs in one or many gelatinous masses, usually attached to plant stems, or twigs near the surface.
Communal egg laying is common to aid in maintaining moisture and temperatures and reducing predation.
Egg incubation period is temperature dependent, ranging from four days to four weeks. Transformation occurs in 6-15 weeks.
Large numbers of froglets disperse into surrounding woods from late May through early July.
Males reach sexual maturity in 1-2 years, females in 2-3 years.
