Habitat and Ecology
It is a diurnal species of lowland tropical moist forest (Twomey and Brown et al. 2008). Individuals were found either in low-lying parts of the forest or in forest adjacent to streams (Twomey and Brown et al. 2008). These streamside habitats are characterized by abundant Heliconia, which appears to be an important breeding site for this species as four tadpole-carrying males were found in or near Heliconia, suggesting these plants are used for tadpole deposition (Twomey and Brown et al. 2008). Frogs not found directly in phytotelmata (water bodies held by plants) were usually on the ground, suggesting that this species is at least partly terrestrial. Egg deposition may also be terrestrial, as an adult pair was observed for several minutes courting in the leaf litter (Twomey and Brown et al. 2008). This species has been only found within intact forest and it is unknown whether it might be able to tolerate any degree of habitat degradation (E. Twomey pers. comm. August 2011).
This species was originally described as Dendrobates captivus (Myers 1982) and included in the genus Adelphobates by Grant et al. 2006.
