2,000 to 5,000 heavily pigmented eggs are deposited in gelatinous strings. Fahrenheit during the night hatched with excellent success. At these temperatures eggs hatched in less than one week. The Wyoming toad feeds primarily on ants, beetles, and other arthropods. Observations conclude that feeding is not restricted to the night in the early summer.
Adults display nocturnal habits at times during the dry part of late summer.
Pesticides were suspected as a cause for the decline period. Wide spread aerial spraying of Fenthion for mosquito control coincided with population declines. Predation was almost identified as a threat to the toad population. Increases in California goals, white pelicans, and raccoons also may have caused the decline of toads. However toads are generally distasteful and somewhat toxic.
