Chorus frog

Pseudacris (the chorus frogs) is a genus of frogs in the family Hylidae. They live in North America. They live as far west as the Pacific coast and as far east as the Atlantic coast.
The name comes from the Greek word "pseudes" (false) and "akris" (locust). Scientists might have named these frogs false-locust because the frog's voices sound like locust's voices: a repeated rasping trill sound. They also might have named these frogs false-"Acris" because there is another frog genus called "Acris".
Taxonomy.
Scientists disagree about which species should be in this genus. Because these frogs can hybridize, meaning make healthy young together, molecular genetic research cannot help much.
Frost "et al." list 19 species in this genus, and AmphibiaWeb lists 17 species, leaving out "P. hypochondriaca" and "P. sierra":

Chorus frogs live anywhere in North America from southern Alaska to southern Baja California, and from the Pacific to the Atlantic.
