Dendrobates leucomelas - Description

Dendrobates leucomelas—the mesmerizing yellow-banded dart frog—is a species that captivates enthusiasts and researchers alike with its intricate combination of physical characteristics, vibrant coloration, and intriguing behaviors. Measuring between 1.5 to 2 inches (3.8 to 5.1 cm), D. leucomelas showcases a compact yet robust physique. Males tend to be slightly smaller than females, emphasizing sexual dimorphism. The body is streamlined with smooth skin and rounded limbs, contributing to its agility and ability to navigate the intricate terrain of its rainforest habitat. The defining feature of D. leucomelas lies in its distinctive coloration, a visual spectacle that has earned it the moniker "yellow-banded dart frog." The body exhibits a striking juxtaposition of jet black and vivid yellow markings. The dorsal region showcases a lattice of intricate black patterns, resembling a tapestry of botanical designs against a radiant yellow backdrop. The limbs often bear these contrasting hues, further accentuating the frog's aesthetic allure. The intricate patterns on the back vary widely among individuals, exhibiting a degree of uniqueness akin to fingerprints. While some may display a dominance of black markings, others showcase a more balanced distribution, contributing to the overall diversity within the species. D. leucomelas engages in diurnal activity, being most active during daylight hours. This behavior aligns with its reliance on visual cues for foraging and navigation within its habitat. Observing these frogs during their waking hours provides a glimpse into their natural behaviors, including hunting strategies and social interactions. D. leucomelas engages in noticable vocalizations during courtship and territorial displays. Males emit moderately loud, melodious trills to attract females, a behavior that adds an auditory dimension to their captivating repertoire.

Geographical Range: 

Dendrobates leucomelas, also known as the yellow-banded dart frog, is native to northern South America. They are primarily found in Venezuela, parts of Brazil, and Colombia.

Habitat Distribution:

These dart frogs inhabit the tropical rainforests and dense vegetation of their native range. They are commonly found near water sources such as small streams and pools.


Dendrobates leucomelas are insectivores and primarily feed on a diet of small invertebrates. In captivity, their diet can include appropriately sized insects such as fruit flies, which should be the staple. Fruit flies should be dusted with Repashy Caclium Plus every feeding. Vitamin A Plus can be administered 1-4x a month depending on age and breeding season. SuperPig can also be used 1-2x a month for breeders if desired, although we do not use it with our tinctorius.

Housing in Captivity:


  • Use a mostly glass terrarium with a secure lid to maintain high humidity. The glass should be 70-90%, with screen being 10-30%. 
  • Provide hiding spots and ample foliage to mimic their natural environment. 
  • Substrate should be an ABG-like mix, FloraBoost, or like substitute, which contains peat moss, fir bark, charcoal, and moss.

Temperature and Humidity:

  • Keep temperatures between 68-80°F (20-27°C) during the day and a slight drop at night.
  • Maintain humidity levels at 80-90% to replicate their rainforest habitat.


  • Provide a natural light cycle with 12/12 on and off and use a full-spectrum LED to promote their well-being. Low powered UVB can be used but should be used only by advanced keepers. 

Full Reproductive Lifecycle:


  • Replicating a wet, dry season may enhance breeding success with this species.
  • Dendrobates leucomelas exhibit complex courtship behaviors. The female will follow the male to a suitable breeding habitat and stroke the back of the male. 
  • Males establish territories and attract females through vocalizations, which are quite loud, and resemble a trill.
  • Females lay eggs, usually between 4-10, in suitable locations, and males fertilize them.

Tadpole Care:

  • Tadpoles are typically moved to water sources by the male, although the female can participate in moving tadpoles.
  • Tadpoles feed on specialized diets consisting of algae, various insect-based protein, and a vitamin complex.
  • Their enclosures should be kept clean by siphoning excess waste with a turkey baster. 


  • Metamorphosis occurs after a few months on average, and juvenile frogs resemble miniature adults.

Sexing and Dimorphism:

  • Males are generally smaller than females, but this is not always reliable. 
  • Females tend to have a more distinct pear-shape.
  • Males call vigorously during rain, so mimic this to parse out males from females

Interesting Facts:

  • Dendrobates leucomelas a known for their vibrant coloration, which serves as a warning to predators due to their toxic skin secretions. This is called aposematism.
  • The toxicity is derived from their diet in the wild, primarily consisting of ants and mites. Millipedes and beetles have also been found to contribute toxins.

Toxin Use for Research:

  • The skin secretions of Dendrobates leucomelas contain potent alkaloid toxins.
  • These toxins have been of interest to researchers for potential medical applications, including pain management and muscle relaxants.
