Life History, Abundance, Activity, and Special Behaviors
The clutch contains about 340-1500 eggs deposited singly or in a few clumps of 7-100 eggs. Females deposit their eggs both by day and night. Recently deposited spawn usually floats on the water surface. Some eggs are deposited on submerged plants. Metamorphosis occurs in summer or autumn; in some cases the tadpoles hibernate. Sexual maturity is attained probably in the 3rd-4th year of life. The majority of adults are 4-6 years old, but the maximum longevity is estimated as 6-11 years. Newly metamorphosed froglets prey upon Aphidinea and Cicadodea, whereas adult frogs feed on spiders and various insects. Active foraging occurs at twilight; during the day, frogs catch only the insects which approach them. This species feeds on spiders, Diptera, Hymenoptera, Coleoptera, and larval Lepidoptera.
