All You Need to Know About the Orange Kneed Tarantula – Species, Habitat, and Care

Orange kneed tarantula

In its natural habitat, the Orange Kneed Tarantula can be found in the scrublands and deciduous forests of Mexico. These spiders prefer to reside in burrows that they dig themselves or take over from other animals. They are primarily nocturnal, spending much of their time hidden in their burrows during the day and emerging at night to hunt for prey. Their diet consists mainly of insects, small rodents, and other arachnids.


The Orange Kneed Tarantula belongs to the genus Euathlus, which is part of the Theraphosidae family. It is a medium-sized tarantula, with females reaching a leg span of around 5 inches, while males are slightly smaller. In addition to its orange knees, this species has a brown body covered in fine hairs, providing it with a velvety appearance.


In the wild, the Orange Kneed Tarantula inhabits the semi-arid regions of Chile, where it can be found hiding in burrows or under rocks. These tarantulas prefer a dry and warm climate, with temperatures ranging between 75°F and 85°F (24°C and 29°C). Their natural habitat consists of scrublands, grassy fields, and desert areas, where they can find ample food and suitable conditions for survival.


Providing proper care for the Orange Kneed Tarantula is essential for its well-being. They are relatively low-maintenance pets, making them suitable for both beginner and experienced tarantula keepers. A well-ventilated terrarium or tank should be set up with a substrate made of a mix of peat moss and vermiculite. This species prefers to hide, so providing a few hiding spots in the form of cork bark or small caves is recommended.

The Natural Habitat of the Orange Kneed Tarantula

These tarantulas prefer areas with a semi-arid climate, where the temperature can range from 20 to 30 degrees Celsius. They are most commonly found in burrows they dig themselves or in abandoned rodent burrows. They use these burrows to seek shelter from predators and extreme weather conditions.

The Orange Kneed Tarantula is well-adapted to its natural habitat. The dry and arid environment allows them to conserve moisture and reduce water loss. They have a hard exoskeleton that helps prevent dehydration. Additionally, their dark coloration helps them blend in with their surroundings, providing camouflage from potential predators.


Orange Kneed Tarantulas are primarily nocturnal creatures, meaning they are most active during the night. During the day, they usually seek refuge in their burrows, where they feel safe and protected. At night, they venture out to hunt for food, which mainly consists of insects and small invertebrates.

These tarantulas are generally docile and non-aggressive, but they will defend themselves if they feel threatened. They have urticating hairs on their abdomen that they can flick as a defense mechanism. These hairs can cause irritation and discomfort to potential predators or humans if they come into contact with them.

Conservation Status

The Orange Kneed Tarantula is not currently listed as a threatened species. However, like many other tarantula species, habitat destruction and collection for the pet trade pose potential threats to their population. Responsible pet ownership and the protection of their natural habitat are essential to ensure their continued survival in the wild.

Caring for the Orange Kneed Tarantula: Tips and Guidelines

Creating the Perfect Enclosure

Start by choosing a suitable tank or terrarium that provides enough space for your tarantula to move around comfortably. A 10-gallon tank is generally sufficient, but larger is always better. Ensure that the enclosure has a secure lid to prevent any escapes.

Next, line the bottom of the tank with a thick layer of substrate. Peat moss or coconut fiber substrate is ideal for maintaining the proper humidity level. It should be deep enough for the tarantula to burrow if it desires.

Maintaining Proper Temperature and Humidity

The Orange Kneed Tarantula requires a temperature range between 75°F and 85°F (24°C and 29°C). To achieve this, a heat pad or under-tank heater can be placed on one side of the enclosure to create a temperature gradient. This will allow the tarantula to regulate its body temperature easily.

In terms of humidity, Orange Kneed Tarantulas prefer a humidity level of 70% to 80%. This can be achieved by misting the tank substrate lightly with water once or twice a week. Keep a hygrometer in the tank to monitor the humidity levels regularly.

Feeding and Handling

Orange Kneed Tarantulas are carnivorous and primarily feed on insects and small invertebrates. They should be offered a variety of prey, such as crickets, mealworms, and cockroaches. Feed them once or twice a week, ensuring the prey is of appropriate size.

Regular Maintenance

To maintain a healthy environment for your Orange Kneed Tarantula, it’s necessary to undertake regular maintenance tasks. This includes removing any uneaten prey or molting remains, as well as periodically cleaning the tank and replacing the substrate.

Regularly monitor your tarantula for any signs of illness or distress, such as lethargy, loss of appetite, or abnormal behavior. If you notice any concerns, it’s crucial to consult a veterinarian with experience in exotic animals.
