The Yellow-banded poison dart frog (Dendrobates leucomelas), also known as yellow-headed poison dart frog or bumblebee poison frog, is a species of frog in the Dendrobatidae family.

Distribution and Habitat[]

Dendrobates leucomelas is found in the northern part of continent of South America, most notably in Venezuela. It is also found in parts of Guyana, Brazil, and the extreme easternmost part of Colombia. This frog is normally found in very humid conditions in tropical rain forests, close to fresh water. It is often found on flat rocks, trees, plants (notably bromeliads), and the leaf litter of the forest floor. During the dry season, specimens are known to congregate in damper places, such as under rocks or fallen tree trunks.

Dendrobates leucomelas' natural habitat is tropical, and not subject to great seasonal temperature variations. Typically, temperature variances are related to elevation and time of day, and range from the low 20s to the low 30s °C. In captivity, care must be taken not to overheat the frogs, as they can be sensitive to higher temperatures.

Although preferring high humidity levels, this species can handle lower humidity levels much better than other species in the genus. Specimens can also be found in the seasonally drier forest islands in its natural range, and at elevations ranging from sea level to 800 metres AMSL.


Dendrobates leucomelas is one of the largest species in the genus Dendrobates, with a snout-to-vent length between 3.1 and 5 cm (1.2 and 2.0 in). Average adult size, however, rarely exceeds 4 cm (1.6 in). Their average weight is reported as being around 3 g (0.11 oz). Females tend to be slightly larger than the males, but otherwise, little in their appearance can be used to determine the sex of the species.

Like most poison dart frogs, the yellow-banded poison dart frog has evolved aposematic coloration as a warning to potential predators that it will make an unpalatable or toxic meal.

Predominantly, these frogs have a bright yellow coloration with varying numbers of broad black stripes and/or spots that extend over the whole body. Some morphs are orange in color, and variations exist within the species (naturally occurring and not morphs solely within the exotic pet community) that dictate the extent of these markings ranging from fine spots to thick, unbroken banding.

They have glandular, adhesive pads on their toes (which aid in climbing and positioning) and, in common with other species in their order, they have a short, protrudable, unnotched, sticky tongue, which extends to catch prey.


Dendrobates leucomelas is diurnal by nature, and are known to be fiercely territorial. They live in small groups in the wild, and will attack neighbouring groups with surprising ferocity for creatures of their size. They will also warn off rivals by emitting loud calls; Dendrobates leucomelas is known to have one of the loudest calls among poison dart frogs; theirs can be heard from some distance and is described as an innocent-sounding, bird-like trill. Dendrobates leucomelas, as with all frogs, can also call to attract members of the opposite sex. Uniquely, it is also the only poison dart frog to estivate during dry spells.


Dendrobates leucomelas reproduce sexually. The mother lays her fertilized eggs (zygotes) in a body of water. When they hatch, they are called tadpoles.


Like all Dendrobatidae, Dendrobates leucomelas frogs secrete toxins from their skin, which they gain from eating certain unspecified arthropod prey. It is uncertain precisely which arthropods lend their toxicity to which genus of Dendrobatidae, but one such arthropod is thought to have been identified as a possible source of the toxin for Dendrobatidae Phyllobates terribilis (aka the golden poison frog), and it is a local variant of the Melyrid beetle.

Dendrobatidae toxins vary from species to species, but some are extremely potent neurotoxins. The alkaloid toxins, secreted from the frogs' skin, interfere with nerve impulses, which can lead to heart failure or fibrillation.

Husbandry and Conservation Status[]

This species' relative ability to withstand broad variations in humidity and temperature, combined with its comparatively bold nature, make it a popular choice for those enthusiasts and amateur herpetologists involved in the exotic pet community. It is widely seen as being an ideal starter species for amateur hepetologists wishing to keep poison dart frogs for the first time.

The species' robustness, relatively common numbers in the wild, and widespread natural distribution has helped maintain this frog's status of "Least Concern" on the International Union for Conservation of Nature's conservation red list, despite some overharvesting of wild specimens for the exotic pet trade. The species' ability to be easily bred in captivity has led to a fall in prices within the exotic pet trade, which is an alleviative factor to the problem of overharvesting.

Once in captivity and removed from their natural sources of food, Dendrobatidae lose much of their toxicity. Dendrobates leucomelas, however, is not one of the three main Dendrobatidae species used for poison darts by native South American tribal hunters, so toxicity levels are somewhat lower in wild-caught specimens than in the Phyllobates genus.
