Physical Characteristics


The Brazilian blue tarantula, also known as the Avicularia avicularia, is a medium-sized species of tarantula. As an adult, it typically reaches a leg span of around 4 to 5 inches (10-12 cm), with females being slightly larger than males.


As the name suggests, the Brazilian blue tarantula is famous for its stunning blue coloration. The carapace, abdomen, and legs of this tarantula species display various shades of blue, ranging from metallic blue to vibrant cobalt. The abdomen often has intricate patterns of lighter and darker blue hues, creating a mesmerizing visual display.


Like other tarantulas, the Brazilian blue tarantula is covered in a dense layer of hairs, known as setae. These setae serve various purposes, such as sensing the environment, thermoregulation, and defense mechanisms. The setae of the Brazilian blue tarantula are typically dark brown or black, providing a beautiful contrast to its vibrant blue exoskeleton.

Natural Habitat

Native Region

The Brazilian blue tarantula is native to the tropical rainforests of South America, particularly found in Brazil, French Guiana, Suriname, and Guyana. Within these regions, they inhabit diverse ecosystems, including lowland forests, swamps, and even urban areas.

Preferred Environment

In the wild, the Brazilian blue tarantula is primarily arboreal, meaning it spends most of its time in trees and vegetation. They construct intricate silk-lined burrows in tree bark, providing them with a safe retreat and a vantage point for hunting. These tarantulas thrive in warm and humid environments, often found in regions with temperatures ranging between 75-85°F (24-29°C) and a humidity level of approximately 70-80%.

Burrowing Behavior

The Brazilian blue tarantula is an adept burrower, using its strong legs and spinnerets to create silk-lined tunnels within tree bark or natural crevices. These burrows provide protection from predators and serve as a safe haven during molting and periods of rest. They are skillfully constructed, often containing multiple chambers for different activities like hunting, molting, and reproduction.

Feeding Habits

Dietary Preferences

The Brazilian blue tarantula is an opportunistic carnivore and primarily feeds on a diet of insects and other small invertebrates. Its main prey includes crickets, cockroaches, moths, and occasionally small spiders. In captivity, they can also be fed with appropriately sized mice.

Hunting Techniques

When hunting, the Brazilian blue tarantula relies on its impressive agility and excellent eyesight. It often waits patiently outside its burrow or perched on tree branches, using camouflage to blend into the surroundings. Once a suitable prey item comes within striking distance, the tarantula pounces with remarkable speed and accuracy, immobilizing its prey with a venomous bite.

Feeding Frequency

The feeding frequency of the Brazilian blue tarantula varies depending on factors such as age, size, and environmental conditions. Adult tarantulas typically require feeding once or twice a week, while younger individuals may eat more frequently. It is essential to provide a balanced diet for their nutritional needs and adjust the feeding schedule accordingly.


Mating Behavior

The mating behavior of the Brazilian blue tarantula involves a ritualistic courtship dance performed by the male to attract the female. The male tarantula taps his legs on the ground and gently touches the female’s legs to signal his intentions. If the female accepts his advances, she may respond by drumming her legs or reciprocating the touching behavior. Mating typically occurs on a firm surface within the female’s burrow.

Egg Laying

After successful mating, the female Brazilian blue tarantula produces an egg sac containing several hundred eggs. She carries this sac with her fangs and spinnerets, ensuring its protection and providing optimal conditions for development. The female carefully guards the eggs, periodically rotating the sac to maintain proper humidity levels and temperature.

Parental Care

The Brazilian blue tarantula exhibits remarkable parental care compared to many other tarantula species. After the eggs hatch, the spiderlings emerge from the sac and remain in close proximity to their mother. She continues to protect and care for them, often providing regurgitated food until the spiderlings become independent and disperse.

Predators and Defense Mechanisms

Natural Enemies

Despite its impressive appearance, the Brazilian blue tarantula faces predation from various natural enemies. Predatory birds, snakes, lizards, and even other larger spiders are known to prey on tarantulas in their natural habitat. However, the tarantula’s venom, striking speed, and defensive behavior help them minimize the threats posed by these predators.

Crypsis and Camouflage

The Brazilian blue tarantula employs crypsis and camouflage techniques to protect itself from potential predators. Its vibrant blue coloration, combined with its hairy exoskeleton, helps it blend effortlessly into the surrounding foliage, making it difficult for predators to spot. Additionally, when threatened, the tarantula may raise its front legs and assume an aggressive posture to deter predators.

Captive Care

Housing Requirements

When keeping the Brazilian blue tarantula in captivity, ensuring appropriate housing conditions is crucial for its well-being. A spacious terrarium with sufficient hiding spots, such as bark or artificial plants, should be provided. It is essential to avoid overcrowding and maintain a proper substrate, such as coconut fiber, for burrowing.

Temperature and Humidity

Maintaining the correct temperature and humidity is essential in replicating the Brazilian blue tarantula’s natural habitat. The terrarium should be kept at a temperature range of 75-85°F (24-29°C), with a humidity level of approximately 70-80%. Mist the enclosure regularly to provide the necessary humidity and ensure proper ventilation to prevent mold or bacterial growth.

Feeding and Nutrition

In captivity, the Brazilian blue tarantula can be fed a diet of appropriately sized insects, such as crickets, roaches, and mealworms. It is important to offer a varied diet to mimic their natural feeding habits and ensure a balanced nutritional intake. Always remove any uneaten prey to maintain a clean and hygienic enclosure.

Handling Tips

Handling the Brazilian blue tarantula should be done with caution to avoid stress or injury to both the spider and the handler. As primarily arboreal species, they are not accustomed to frequent handling and may become defensive or agitated. If necessary, it is recommended to use proper handling tools and techniques or seek guidance from experienced keepers.
