Few movements occur during most of the year, but they will travel up to several meters on rainy nights. Movements to and from breeding ponds are rarely extensive. Breeding and egg laying normally occur from late winter to the end of March. Chorusing males may be heard during this period, but agricultural irrigation may elicit vocalizations in any month. Females lay numerous small, irregular clusters containing 10 to 42 eggs.
Eggs hatch rapidly, normally within two weeks.
Tadpoles may compete for food or space with other amphibian larvae. Because of their secretive behavior during most of the year, adults probably avoid predators. Dense populations of tadpoles may be heavily preyed upon by wading birds, or certain species of mammals. Predation on arthropods by spadefoot tadpoles. Bragg, A. N. 1964.
