The Brilliant-thighed Poison Frog is a diurnal (active during the day) species found in the leaf litter of tropical forests. It is named after its brightly colored thighs. The male frogs are highly territorial and will fight males that come into their territory.

Mating occurs between November and April, peaking in January. The females lays between 8 – 17 eggs between leaves on the ground. The male sits and watch guard over the eggs until they hatch. Then, the male carry the tadpoles on their back to a pool of water where they will complete their metamorphosis.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Brilliant-thighed Poison Frog as Least Concern for Extinction. They have a wide range covering most of northern South America and are thought to be common throughout it. Deforestation threatens local populations but not the overall status of the frog.
