Spring peeper spends majority of life on the forest floor (terrestrial animal).

Spring peeper is nocturnal creature (active during the night).

Spring peeper is a carnivore (meat-eater). Its diet is based on beetles, ants, flies, mosquitoes and spiders.

Natural enemies of spring peepers are large frogs, fish, birds, skunks and snakes.

Spring peeper hides in the mud or in deep water during the summer to avoid extremely high temperatures.

Spring peeper hibernates during the winter, hidden under the logs, piles of leaves or loose bark of trees. It can survive almost complete freezing of the body thanks to glycerol (substance produced in the body), which acts like an anti-freeze that prevents mechanical damage of cells.

Name "spring peeper" refers to loud, sleigh bell-like calls which males produce at the beginning of the spring.

Males have large vocal sacs that look like balloons when they are inflated. They produce short, high-pitched, peeping calls (around 90 calls over a period of 4 hours) during the night to attract females. Females choose the right partner for mating by the speed of calls (older, stronger males produce fast calls, young males produce slow calls).

Mating season of spring peepers takes place from March to June in the northern parts and from October to March in the southern parts of their range.

After successful fertilization, female wraps 800 to 1.000 eggs around aquatic plants in the shallow pools. Spring peepers do not show parental care (eggs are left on their own). Tadpoles emerge from eggs 6 to 12 days after fertilization.

Tadpoles feed on algae, detritus and zooplankton until they transform into young frogs. Process of metamorphosis lasts 90 to 100 days. Spring peepers reach sexual maturity at the age of one year but they rarely breed before they reach the age of 3 years.
