[1][2] They occur in northern Mexico (Coahuila), the United States east of the Rocky Mountains, and in southern Ontario, Canada.
[1] They are more aquatic than other members of the family, and are generally associated with permanent bodies of water with surface vegetation.
This is a quite important aspect of their survival, as adult cricket frogs suffer high mortality rates when submerged in poorly oxygenated water (typically less than 24 hours on average in water that is ~1.2 mg/L).
[3] The common and scientific names refer to their call, which resembles that of a cricket.
Cricket frogs from other locales are unable to aurally process other calls, leading to mating isolation among the species.
