California myotis are found in deserts and arid basins. They drink at small waterholes, and when they forage, they fly low and slow over water and other open areas, and at forest edges. Many California myotis are active in winter, but some that live at higher elevations or farther north hibernate. Mating usually occurs in the fall, and sperm is stored in the female's uterus until spring, when ovulation and fertilization occur. A single pup is born in June or July, when food is plentiful. The young develop rapidly and can fly in about a month.
