Physical Appearance


The Mexican flame knee tarantula is a medium-sized spider, with adult females reaching a leg span of up to 6 inches (15 centimeters) and males being slightly smaller. They are considered to be one of the larger species of tarantulas.


The Mexican flame knee tarantula gets its name from its vibrant and striking coloration. Its body and legs are adorned with a rich combination of fiery red and orange hairs, which stand out against its contrasting black body. This coloration not only makes them visually stunning but also provides effective camouflage in their natural habitat.

Leg Span

As mentioned earlier, the Mexican flame knee tarantula can have a leg span of up to 6 inches (15 centimeters). Their long and robust legs allow them to move swiftly and with precision, making them skilled predators.


The carapace of the Mexican flame knee tarantula is dark black and glossy, providing protection for its vital organs. It is slightly rounded in shape and sits on the front of the spider’s body. The carapace, along with the colorful hairs on its legs, contributes to the tarantula’s overall striking appearance.


The abdomen of the Mexican flame knee tarantula is large and bulbous. It is covered in black bristles, complementing the coloration of its carapace. The abdomen stores the spider’s vital organs and also serves as a reservoir for food and water during times of scarcity.


Territorial Nature

Mexican flame knee tarantulas are known to be relatively territorial creatures. They stake out their own territory, which they defend from intruders, be it prey or other spiders. They exhibit an extraordinary level of aggression when it comes to protecting their space, often displaying dominance through posturing and physical combat.

Hunting Techniques

These tarantulas are skilled hunters, relying on their keen senses to detect and capture prey. They primarily use their legs to feel vibrations on the ground and detect any potential food sources. Once they locate their prey, they swiftly chase them down and immobilize them using their venomous fangs.

Defensive Mechanisms

When threatened or provoked, the Mexican flame knee tarantula has several defensive mechanisms to protect itself. Their first line of defense is their ability to flick urticating bristles from their abdomen using their hind legs. These bristles can irritate the skin and eyes of predators, deterring them from further attack. If the threat persists, they will resort to biting and injecting venom, which is highly uncomfortable and can cause mild to moderate pain in humans but is generally harmless.

Burrowing Habits

Mexican flame knee tarantulas are known for their burrowing habits. They create intricate burrows in the ground, providing them with a safe and secure place to rest, molt, and even lay their eggs. These burrows can be quite deep and have multiple entrances, allowing for easy access and escape routes.

Web Spinning

Unlike some other species of tarantulas, the Mexican flame knee tarantula does not rely heavily on web spinning to catch prey. They primarily rely on their agility and hunting skills to chase down and capture their meals. However, they may still spin loose webs within their burrows, which serve as a sensory mechanism to detect approaching prey or potential threats.

Life Cycle

Mating Rituals

The mating rituals of Mexican flame knee tarantulas are a fascinating display of courtship behavior. Male tarantulas perform elaborate dances and drumming patterns to attract the attention of the female. These dances involve tapping their legs on the ground, creating rhythmic vibrations that resonate through the environment. If the female is receptive, she will respond positively, and mating can commence.

Egg Laying

After successful mating, the female Mexican flame knee tarantula will lay a clutch of eggs. She carefully constructs an egg sac out of silk, which she attaches to the walls of her burrow. These egg sacs can contain hundreds of eggs, which are then protected and incubated by the mother until they are ready to hatch.

Egg Incubation

The female tarantula diligently guards her egg sac, ensuring optimal conditions for incubation. She will carefully regulate the moisture and temperature within the burrow, ensuring the eggs develop properly. This process can take several weeks or even months, depending on environmental factors.


Once the eggs hatch, a mass of tiny spiderlings emerges. These spiderlings are miniature versions of their parents and are completely independent from the moment of birth. They disperse from the nest, using newly acquired hunting skills to fend for themselves.

Molt Cycle

Tarantulas, including the Mexican flame knee, undergo a process called molting. Molting is the shedding of their exoskeleton to allow for growth. During this cycle, the tarantula’s body and legs harden and become vulnerable. They retreat to a safe location within their burrow to molt, as the process leaves them temporarily defenseless.


Carnivorous Diet

Mexican flame knee tarantulas have a strictly carnivorous diet. They primarily feed on insects and other small invertebrates found in their environment. Their diet can include crickets, grasshoppers, beetles, and even small vertebrates such as lizards or mice, depending on the size and capabilities of the tarantula itself.

Prey Selection

When it comes to selecting prey, Mexican flame knee tarantulas are opportunistic hunters. They prey on a wide range of insects and invertebrates that cross their path. Their hunting techniques are swift and efficient, relying on their speed and powerful fangs to immobilize their victims.

Feeding Mechanics

Mexican flame knee tarantulas capture their prey using their fangs and inject venom, paralyzing the prey and beginning the digestion process. They have strong chelicerae, which they use to tear apart their prey into smaller, more manageable pieces. Once the prey is subdued, they proceed to consume it.

Digestion Process

The digestion process of Mexican flame knee tarantulas starts externally. They release digestive enzymes onto their prey, which starts breaking down the tissues. The liquefied prey is then sucked into the tarantula’s mouthparts using a combination of sucking and muscular contractions. Once inside, the prey is further broken down by the tarantula’s internal digestive system.

Feeding Frequency

Mexican flame knee tarantulas have varying feeding frequencies depending on their size, age, and overall health. Younger individuals tend to require more frequent feedings, sometimes consuming prey on a weekly basis. As they mature, their feeding frequency may decrease to once every couple of weeks or even longer. Like all tarantulas, they have the ability to go extended periods without food due to their low metabolic rates.
