Mexican Flame Knee Tarantula
Brachypelma auratum
The Brachypelma auratum, known as 'Mexican Flame Knee Tarantula'. Long confused with B. smithi, it is distinguished by a unique chromatic pattern: the knees present a marked red/orange flame on a deep black background, surmounted by a distinct horizontal creamy white band. Powerful (5.9-6.3 inches legspan) and with a light-bordered carapace, it is a long-lived and placid terrestrial spider, but slightly more reluctant to handling than its cousins.

Descrição da espécie
Geographic Origin and Habitat: World Spider Catalog lists Brachypelma auratum from Mexico. This taxonomic distribution entry does not characterize habitat conditions.
Taxonomy and Genetics: World Spider Catalog lists Brachypelma auratum Schmidt, 1992 as an accepted species in Theraphosidae. The cited taxonomic entry does not provide genetic results.
Behaviour and Habits: The cited taxonomic catalog does not provide behavioural observations for this species.
Morphology and Sexual Dimorphism: The cited taxonomic catalog entry does not provide a morphological description or sexual-dimorphism measurements; none are inferred here.
Cuidado, criação e companheiros de tanque
Terrarium Setup: A peer-reviewed conservation profile reports Brachypelma auratum as fossorial: it modifies previously excavated burrows or can excavate its own, including natural small cavities under debris such as large rocks and tree roots. This field observation does not establish enclosure dimensions, substrate depth, materials, or a captive setup protocol.
Lighting and Heating: The profile reports that the species primarily inhabits Balsas dry forest on the inland side of the Sierra Madre del Sur. This natural-habitat statement does not set a lighting or heating schedule for captivity.
Humidity and Hydration: The cited profile does not quantify a captive humidity target or hydration protocol.
Feeding and Supplementation: The cited profile does not document captive diet, feeding frequency, quantities, or supplementation.
Compatibility and Coexistence: The cited profile does not provide a cohabitation recommendation.
Health and Common Diseases: The cited profile does not provide clinical disease, treatment, or veterinary-management guidance.

Perfil de invertebrados terrestres
- Dieta
- Carnivore
- Brachypelma auratum is an opportunistic ambush predator that thrives on a diet of appropriately sized live insects. Crickets, roaches, and mealworms make excellent staple feeders for this species. Prey should be gut-loaded and occasionally dusted with supplements to ensure optimal nutrition. It is important not to overfeed, as a highly distended abdomen can increase the risk of fatal injuries from falls. Remove any uneaten live prey after 24 hours to prevent them from stressing or injuring the spider.
- Tamanho adulto
- 14 cm
- Estilo de vida/Microhabitat
- Terrestrial
- Brachypelma auratum is perfectly adapted to its specific ecological niche, requiring a setup that closely mimics its natural environment. Terrestrial species need deep, specialized substrate for burrowing, while arboreal species require vertical cork bark tubes and elevated hides. They are generally solitary creatures that should be housed individually to prevent predation. A proper water dish and an appropriate microclimate are essential components of their enclosure. They lead a sedentary lifestyle, meaning they do not require excessively large enclosures compared to active reptiles.
- Ciclo de atividades
- Nocturnal
- Like most tarantulas, Brachypelma auratum is primarily nocturnal, showing the highest levels of activity during the night. They generally remain hidden in their burrows or web tubes during daylight hours to avoid heat and predators. Once the lights go out, they often emerge to sit at the entrance of their hide, waiting to ambush passing prey. Despite being mostly inactive during the day, they may occasionally venture out for water or to adjust their webbing. Maintaining a natural photoperiod is recommended to support this internal circadian rhythm.
- Socialidade
- Solitary
- Brachypelma auratum are fiercely solitary and notoriously cannibalistic arachnids that cannot tolerate the presence of conspecifics under any circumstances. They must be housed individually for the entirety of their lives; attempting to keep multiple spiders together will inevitably lead to a fatal confrontation and the predation of the weaker individual.
- Reprodução
- Oviparous
- Breeding Brachypelma auratum requires careful introduction of the mature male to the female's enclosure to minimize the risk of cannibalism. The male will drum on the substrate to announce his presence and gauge the female's receptivity. After a successful mating, the female will construct an egg sac containing hundreds of eggs. She will guard this sac fiercely for several weeks until the spiderlings emerge. Providing optimal temperature and humidity during this incubation period is critical for the success of the clutch.
- Venenoso
- Yes
- Tolerância de tratamento
- Tolerant
- Handling Brachypelma auratum is generally discouraged by experienced keepers, as it provides no benefit to the spider and introduces significant risks. A fall from even a minor height can rupture their delicate abdomen, resulting in fatal injury. Additionally, they can deliver a painful bite or release irritating urticating hairs if they become stressed or defensive. If they must be moved for enclosure maintenance, the "catch cup" method is the safest and most stress-free approach. Always prioritize the safety and well-being of the animal over the desire to interact physically.
- Brumação
- Não obrigatório
- Tarantulas like Brachypelma auratum do not undergo true brumation, but their metabolism may slow down considerably if exposed to cooler winter temperatures. In captivity, it is best to maintain a stable, warm temperature year-round to ensure healthy growth and digestion. If temperatures do drop slightly, you may notice a decrease in appetite and activity levels. Never allow the enclosure to reach freezing temperatures, as this will quickly prove fatal. Heating should always be provided via a thermostat-controlled heat mat applied to the side, never the bottom, of the tank.
- Muda
- Regular
- Molting is a critical and vulnerable process for Brachypelma auratum, allowing it to grow and regenerate lost appendages. Before molting, they often refuse food for weeks, become sluggish, and may spin a molting mat of webbing. They will typically flip onto their back to shed their old exoskeleton—never mistake a spider in this position for a dead one. It is crucial to maintain adequate humidity during this time and strictly avoid feeding them until their fangs have fully hardened. Disturbing a tarantula mid-molt can be fatal, so they must be left completely alone.
