In late spring or early summer, postmetamorphic juveniles disperse from breeding sites at night. In California, the first rains of November usually initiate adult migration to breeding ponds. They usually stay at the ponds a few days, but some individuals may remain up to several weeks after breeding is completed. Larvae transform during late spring or early summer, usually by the first week of July in central California. They disperse from the breeding sites after spending a few hours or days near the pond margins.
Few movements occur during most of the year.
Breeding and egg-laying normally occur from December through early February. Females lay numest of the year. Before and after breeding, they emerge at night during rains. During breeding, some diurnal activity occurs.
