The Brachypelma hamorii, previously identified as Brachypelma smithi, and commonly referred to as the Mexican Red Knee Tarantula, stands out as one of the most favored species in the tarantula enthusiast community. Often envisioned when picturing a tarantula, it gained widespread recognition through appearances in films like “Indiana Jones” and “Kingdom of the Spiders,” starring William Shatner. Indigenous to Mexico, particularly along the country’s western coast south of Guadalajara, this New World terrestrial species thrives in arid savannas and scrublands.
Designated under CITES protection in 1985 due to declining wild populations from excessive capture for the pet trade, the Mexican Red Knee Tarantula faced additional threats from local populations considering them pests or harbingers of bad luck. CITES protection prevented their eradication and unauthorized exportation, preserving the species. Despite these challenges, the Mexican Red Knee Tarantula remains a staple in the hobby, cherished for its vibrant coloration, distinctive black and orange patterns, gentle demeanor, and straightforward care requirements.
In terms of husbandry, caring for this tarantula, like many Mexican species, proves to be uncomplicated. Spiderlings are housed in small acrylic containers with damp substrate, progressing to juvenile enclosures as they grow. Adult enclosures, typically 2.5 to 5 gallons in size, maintain a dry substrate with occasional water dish overflow. Providing hides and adhering to appropriate feeding practices, such as offering size-appropriate prey, ensures their well-being.
Feeding schedules differ across life stages, with slings receiving small prey items weekly, juveniles fed based on abdomen size, and adults consuming larger prey every other week. Notably, Mexican Red Knee Tarantulas may go extended periods without eating, reflecting their opportunistic feeding behavior. Patience is key, as waiting a few weeks before reattempting feeding is common.
Known for its beauty, docility, and ease of care, the Mexican Red Knee Tarantula is a favorite among enthusiasts. While it may kick hairs that can cause irritation, its venom is generally non-threatening. Recent reclassification from B. smithi to B. hamorii has caused some confusion.
