They are found in woodland streams or grassy fields.
The frogs eat insects, but the tadpoles are herbivorous.
They have dark brown spots in two rows down the back.
There is a bright yellow colour on the inside of the thighs.
The females lay egg masses attached to branches in ponds.
They are nocturnal.
In October, they burrow into sediments at the bottom of ponds and streams and hibernate there for the winter.
They can produce toxic skin secretions that are irritating to humans, but which can also be fatal to predators.
The population can decline due to habitat destruction.
