Brief SummaryRead full entry
It's range is Southern Arizona (Quinlan, Santa Rita, Patagonia, Huachuca, and Pajarito Mts.) and northeastern Sonora (Sierra El Tigre) south along the Pacific Coast foothills of Western Mexico.
These secretive frogs are terrestrial and are found in areas with limestone and other rock outcrops. The frog is nocturnal, spending the day under rocks, or in mines, wells, caves, or fissures (Stebbins 1985, Schwalbe 1990, Goldberg and Schwalbe 2000). When threatened, it inflates to several times its normal size. The skin fold on the belly may be useful in helping it to cling to the sides of caves. There is little life history information available. The longest documented lifespan of a wild individual is 5 years as an adult (Goldberg and Schwalbe unpublished data).
Advertisement calls of frogs from Arizona were significantly longer in duration, higher in frequency, and had longer duration pulses than those of frogs from either New Mexico or Texas; frogs from these later two sites were indistinguishable in these call variables (Goldberg et al. 2004). Their call is ventriloquistic, making them difficult to locate even after they are detected; most are located by their distinctive and loud “Walk-walk” or “Whaa-whaa- whaa-whaa” call. In Arizona, they call from their hiding spots (e.g. crevices) for only two to four weeks on rainy nights after the start of the summer monsoons in late June or July. Frogs call dependably for only two or three nights following the first heavy monsoon storm of the season (Rorabaugh, in AZ PARC 2006).
The diet consists of a variety of invertebrates.
