Southeastern British Columbia, Canada south to western Montana and northern Idaho.
Typically found along river banks and margins, close to springs, and under logs or rocks in wet valleys. During especially arid summers will burrow into piles of leaves or underground to seek cooler temperature. They are almost exclusively nocturnal, coming above ground at night and feeding on other nocturnal creatures like worms and arthropods. Females lay their eggs in wet areas under shelter including logs, damp natural debris, and underground burrows.
Primary color is black with a yellow patch on throat and a stripe down the back that is either yellow, green, orange, or red. Legs are proportionally long with smaller webbed toes. Can reach a maximum snout-vent length of 62 mm. Males and females mate any time between August and October and will sometimes mate in spring months from April to May. Eggs can be distinguished as appearing in grape-sized balls that are held together by one thread. There are about four to 13 eggs per clutch on average.
