The black-legged dart frog (Phyllobates bicolor), also known as the bicolored dart frog or neari in Choco, is the second-most toxic of the wild poison dart frogs.

However, genetic tests have proven these frogs to be uniform-coloured morphs of Phyllobates bicolor.

While it is small, it is just as toxic as Phyllobates bicolor when encountered in the wild.

Two other species, the Kokoe poison dart frog (Phyllobates aurotaenia) and the black-legged dart frog (Phyllobates bicolor) are also used for this purpose.

The bicolor dart frog (Phyllobates bicolor) can range from yellow to orange, from black legs to green legs, to almost a uniform color of any of the aforementioned color morphs.
