Red knee tarantulas, or Mexican red knee tarantulas, are a favorite among pet enthusiasts due to their striking appearance and relatively docile nature. This article provides comprehensive information about red knee tarantulas, including their habitat, physical characteristics, behavior, diet, care requirements, and more.
Habitat and Distribution
Natural Habitat
Red knee tarantulas are native to the Pacific mountain ranges of Mexico. They inhabit semi-arid scrublands, forests, and deserts. These environments provide a mix of dry and slightly moist conditions, which are ideal for their survival. In their natural habitat, they often create burrows in the ground or seek shelter under rocks and logs.
Captivity Requirements
To replicate their natural environment in captivity, provide a terrarium with appropriate substrate and hiding spots. Coconut fiber, peat moss, or a mixture of soil and sand can be used. Maintaining proper humidity and temperature is crucial for their well-being. Regular monitoring and adjustments are needed to mimic their natural conditions.
Physical Characteristics
Appearance
Red knee tarantulas are easily recognizable by their black bodies with bright red or orange bands on their knees. Adult females can reach a leg span of up to 6 inches, while males are generally smaller. They have eight legs, two pedipalps (sensory appendages), and a pair of fangs. Their exoskeleton serves as protection and must be periodically shed through molting.
Molting Process
Molting is an essential part of their growth. As they outgrow their exoskeleton, they must shed it and form a new one. Before molting, tarantulas may show signs such as reduced activity, refusal to eat, and a darkening of their exoskeleton. The process can take several hours and leaves the tarantula vulnerable, so it is important to provide a safe environment during this time.
Behavior and Temperament
General Behavior
Red knee tarantulas are known for their calm and docile nature. They are generally slow-moving and prefer to avoid confrontation. When threatened, they may raise their front legs and display their fangs as a warning. Unlike some other tarantula species, they rarely bite.
Defensive Mechanisms
When feeling threatened, red knee tarantulas rely on urticating hairs on their abdomen. These hairs can be flicked towards predators to cause irritation and discomfort. This defensive strategy is effective in deterring potential threats without resorting to a bite.
Diet and Feeding
Feeding Habits
In the wild, red knee tarantulas feed on insects and small invertebrates. In captivity, their diet should include crickets, mealworms, and roaches. Juvenile tarantulas require more frequent feeding compared to adults. It is important to provide prey that is appropriately sized to prevent injury or stress.
Feeding Schedule
A balanced feeding schedule is essential to maintain health. Overfeeding can lead to obesity and other health issues, so it is crucial to monitor their diet and adjust accordingly. A well-fed tarantula will have a rounded abdomen, indicating good health.
Housing and Enclosure
Enclosure Setup
A glass terrarium with a secure lid is ideal for housing red knee tarantulas. The enclosure should be spacious enough to allow movement and include hiding spots and suitable substrate. Coconut fiber, peat moss, or a soil-sand mix are recommended. Regular cleaning is necessary to remove waste and uneaten prey.
Humidity and Temperature
Maintaining the right humidity and temperature is vital. The ideal temperature range is between 75-80°F during the day, with a slight drop at night. A heat mat or lamp can help achieve this range. Humidity levels should be around 60-70%, and a shallow water dish should be provided. Regular misting and monitoring are essential for maintaining these conditions.

Handling and Interaction
Handling Guidelines
While red knee tarantulas are generally docile, handling should be approached with care. Frequent handling can cause stress. Limit handling to necessary situations, such as during enclosure cleaning or health checks. Use gentle movements and avoid sudden motions that may startle the tarantula.
Health Precautions
Always wash your hands before and after handling to prevent the transfer of oils or dirt. This practice helps ensure the tarantula’s health and reduces the risk of potential issues.
Health and Common Issues
Common Health Problems
Red knee tarantulas are generally hardy but can experience health issues. Common problems include dehydration, mites, and injuries. Dehydrated tarantulas may appear lethargic and have a shriveled abdomen. Providing a shallow water dish and maintaining proper humidity can help prevent dehydration.
Treatment and Prevention
Mites can be treated by cleaning the enclosure thoroughly and removing affected substrate. Injuries should be monitored for signs of infection, and a veterinarian experienced with exotic pets should be consulted if necessary.
Breeding and Reproduction
Breeding Behavior
Breeding red knee tarantulas can be challenging but rewarding. Males mature faster than females and can be identified by their smaller size and tibial hooks on their front legs. Introduce males and females for mating with caution, as females may be aggressive towards males.
Rearing Spiderlings
After successful mating, the female will lay eggs in a silk sac and guard it until the spiderlings hatch. The incubation period can vary, and the spiderlings will remain with the mother for a short time before becoming independent.
Conservation Status
Protection Efforts
Red knee tarantulas are listed on Appendix II of CITES, which helps regulate the trade of wild-caught specimens to ensure sustainable populations. Captive breeding programs have been established to support conservation efforts and provide a sustainable source for the pet trade.
Ethical Considerations
When acquiring a red knee tarantula, choose reputable breeders who adhere to ethical practices. Supporting conservation efforts helps protect wild populations and ensures the continued availability of these fascinating arachnids for future generations.
Conclusion
Red knee tarantulas are captivating creatures that make intriguing pets for those willing to meet their specific care requirements. Their striking appearance and relatively calm demeanor make them a favorite among tarantula enthusiasts. By understanding their natural habitat, behavior, and needs, you can provide a suitable environment for these fascinating arachnids. Whether you are a novice keeper or an experienced hobbyist, red knee tarantulas offer a unique glimpse into the world of tarantulas and the wonders of the natural world.
