Quick ID
Field Notes
A small dendrobatid frog typically measuring 0.75–1.25 inches (1.9–3.2 cm) in length. Body is compact and robust with relatively short limbs. Dorsal coloration is brilliant orange-yellow to golden yellow, overlaid with distinctive black or dark brown reticulated markings that form a complex lacy or net-like pattern across the back, head, and limbs. The reticulations are variable in density and arrangement among individuals, creating a unique pattern for each frog. The ventral surface is similarly colored, displaying the same striking orange-yellow base with black markings. The head is rounded and relatively broad. Skin is smooth and granular. Digits are slightly expanded at the tips but lack the prominent toe pads of some other dendrobatids. Eyes are relatively large and dark. This species is highly toxic, sequestering alkaloid compounds in the skin as a chemical defense. Inhabits the floor of humid tropical rainforests, particularly in areas with dense moss, leaf litter, and low vegetation near streams and seepage areas in western Ecuador. Diurnal and terrestrial, remaining close to the forest floor among moss-covered logs, vegetation, and root systems. Diet consists of small arthropods, particularly small beetles, mites, and other tiny invertebrates, which are likely the source of the alkaloid compounds concentrated in the skin.
