HABITAT

Ephemeral fishless ponds.  These frogs inhabit forests with sandy, loose soil.  They usually spend the day in underground burrows, emerging at night to feed.  Tadpoles form large, conspicuous schools.

BREEDING SEASON

Breeding occurs after extremely heavy rains of several inches or more which stimulates the entire population to breed.   Breeding occurs in ephemeral or temporary wetlands.  Tadpoles develop quickly and the metamorphs typically emerge within three weeks.
