Western Striped Chorus Frog (Pseudacris triseriata & P. maculata)

Description: Tan to light brown back; belly is white. Three brown stripes (or rows of spots) down the back. White line along upper lip.

Call: Insect-like trill, speeding up and rising in pitch toward the end; likened to the sound produced by running a thumb across teeth of a comb. When you approach a pond where these frogs are calling as soon as one individual is spooked and stops calling, all the frogs stop calling.

Habitat: Roadside ditches, marshes, and flooded areas, grassy-wetland areas,

Diet:: small flying and aquatic insects.

Size: 2-3.8 cm (0.75-1.5 in)

Natural History: Chorus frogs are commonly heard, but seldom seen; they are extremely wary. They climb on and hide in grasses and sledges, maybe found far from rivers/streams. If disturbed they will hide in grassy areas. Call and breed in early (March) spring.

The Chorus Frog in Nebraska is currently divided into species the Western Chorus Frog and the Boreal Chorus Frog. Studies have shown that these species can be separated using call and morphology (Platz 1989). However at this time no simple field character is available to easily distinguish these species.
