Rio Grande Chirping Frog

Eleutherodactylus cystignathoides

Rio Grande Chirping Frog 2

Originally native to Mexico, the Rio Grande Chirping Frog has been widely introduced in Texas. Unlike most other frogs, it lays its eggs in soil and the embryos develop directly into tiny frogs before hatching; this allowed the eggs to "hitch a ride" undetected in nursery plant potting soil. In their native range these tiny frogs favor riparian environments, but in Texas they can be found in almost any kind of vegetation near humans. Listen for their high-pitched, insect-like chirps and trills at night: http://www.californiaherps.com/noncal/misc/miscfrogs/pages/e.c.campi.sounds.html
