Species description
Geographical Origin and Habitat: Native to the high canopy of the Amazon rainforest across Brazil, Colombia, Peru, and Bolivia. It inhabits the upper layers of the forest, descending closer to the ground only during the rainy season to lay eggs on leaves overhanging slow-flowing rivers or ponds.
Taxonomy and Genetics: One of the largest tree frogs in the world, with females reaching sizes of 11 to 14 cm. It features a bright green dorsal surface, cream-colored undersides, and distinct white and dark spots on the flanks and limbs. Eyes are large and greyish-silver. It possesses specialized glands that secrete a waxy lipid layer used to prevent dehydration.
Behavior and Habits: Strictly nocturnal and arboreal. Instead of jumping, it climbs slowly using opposable thumbs and fingers with a firm, monkey-like grip. During the day, it sleeps exposed on branches, having wiped its waxy secretions over its skin to lock in moisture.
Morphology: Females are significantly larger, heavier, and broader than males. Males possess vocal sacs and emit loud, deep vocalizations during the breeding season.
Care, breeding and tankmates
Terrarium Setup: Requires a very tall, spacious, and highly ventilated vertical enclosure (minimum 60x45x90 cm). Furnish with thick climbing branches, bamboo tubes, and sturdy large-leaved plants (e.g. Monstera deliciosa) to support their weight. Avoid waterlogged soils or boggy substrates.
Lighting and Heating: Provide daytime temperatures of 26-29°C using an overhead heating source for basking, with a nighttime drop to 22-24°C. A 5.0-10.0 UVB source is essential for skeletal health and to prevent metabolic bone disease.
Humidity and Hydration: Keep humidity levels fluctuating between 50-60% during the day and 80-90% at night. Mist the enclosure every other evening. Stagnant humidity and poor ventilation will cause fatal skin infections.
Feeding and Supplementation: Voracious nocturnal hunter. Feeds on large crickets, locusts, and roaches. Provide food using long feeding tongs or in dry, feeding containers. Dust prey items with calcium and D3 weekly.
Compatibility: Peaceful when kept in small groups (e.g. one male and two females) provided there is ample vertical space. Avoid housing specimens of wildly different sizes to prevent accidental injury or stress.
Health and Common Diseases: Highly sensitive to poor ventilation and constant high humidity, which lead to fungal skin infections and ulcers. Susceptible to metabolic bone disease and injury from falls if enclosure climbing pathways are unsafe. Avoid handling to prevent chemical irritation to the frog's sensitive skin.

Amphibian profile
- Diet
- Insectivore
- The diet of Phyllomedusa bicolor must be carefully managed to ensure optimal health and longevity. In its natural habitat, Phyllomedusa bicolor typically consumes a variety of specific prey items or plant matter. Captive specimens require a similarly balanced intake, often supplemented with essential vitamins and calcium. It is important to offer food that is appropriately sized to avoid choking or digestive issues. Regular monitoring of their feeding response helps in identifying any potential health problems early.
- Life expectancy
- 10-15 years
- The catalog uses 10–15 years as its concise reference range. AmphiBIO v1 instead reports a documented maximum longevity of 10.3 years for the species. An observed maximum is not the same as a typical expectation: specimen origin, sample size and husbandry conditions can explain differences among sources, so this figure should be read as a recorded limit rather than a promise of survival.
- Adult size
- 11 cm
- The catalog's scalar value is 11 cm. The AmphiBIO v1 source reports a maximum adult measurement of 13.5 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
- Lifestyle/Microhabitat
- Arboreal
- The lifestyle of Phyllomedusa bicolor varies greatly depending on whether they are terrestrial, arboreal, aquatic, or semi-aquatic. Designing an enclosure that accommodates their specific mode of living is essential for their physical and mental health. This includes providing the right substrate, climbing branches, or water features as needed. A proper setup allows Phyllomedusa bicolor to exercise, hide, and thermoregulate effectively. Understanding their lifestyle choices helps in creating a thriving captive environment.
- Activity cycle
- Nocturnal
- The activity pattern of Phyllomedusa bicolor typically dictates when they feed, explore, and rest. Depending on their biology, they may be predominantly active during the day, night, or twilight hours. Replicating appropriate lighting and temperature cycles is crucial for maintaining their natural rhythm. Disruptions to this schedule can lead to stress and a decline in the health of Phyllomedusa bicolor. Keepers should try to interact with them during their most active periods to minimize disturbance.
- Sociality
- Solitary
- The behavior of Phyllomedusa bicolor is deeply influenced by its natural instincts and environment. These creatures exhibit unique social and territorial behaviors that must be respected in captivity. Providing a habitat that mimics their wild surroundings can greatly reduce stress and encourage natural activities. Phyllomedusa bicolor may show specific defensive or communicative displays when interacting with its environment. Observing these behaviors is key to understanding their overall well-being and comfort.
- Reproduction
- Oviparous
- Reproduction in Phyllomedusa bicolor requires specific environmental triggers such as temperature and humidity changes. Breeding these animals in captivity can be challenging and often demands a dedicated setup. Once successful mating occurs, careful attention must be given to the incubation of eggs or the care of live young. The offspring of Phyllomedusa bicolor are usually fragile and require highly specific conditions to thrive. Keepers must thoroughly research their reproductive cycle to achieve positive breeding results.
- Toxicity
- Mildly toxic
- This species secretes a complex mixture of bioactive peptides from its skin when stressed, a defense mechanism known as 'kambo'. These peptides are highly toxic to potential predators and have powerful physiological effects on humans, causing severe nausea, vomiting, and tachycardia. Despite their toxicity in the wild, the secretions are used in traditional Amazonian medicine.
- Life stage
- Metamorphosis
- The aquatic tadpoles are robust and feed on various plant and animal matter in the murky waters of forest pools. Metamorphosis can take several months, during which they grow significantly before developing legs and absorbing their tails. The young froglets are miniature replicas of the adults and immediately adopt a completely arboreal lifestyle.
- Handling tolerance
- Display only
- Handling is highly discouraged. They secrete powerful waxy toxins (used in Kambo ceremonies) when stressed, which can cause severe adverse reactions in humans.
- Brumation
- They do not brumate and require year-round tropical temperatures, though they appreciate excellent ventilation to prevent stagnant, overly wet conditions.
- Molting
- Regular
- They perform an elaborate 'wiping' behavior, using their legs to spread a waxy lipid secretion over their entire body to prevent desiccation during the heat of the day.
