Natural History

In the wild, Brachypelma hamorii inhabits dry forests and scrubland regions along Mexico’s Pacific coast. These tarantulas construct burrows beneath rocks, roots, and natural debris where they remain sheltered during the day.

The Mexican Red Knee Tarantula typically emerges at night to hunt insects and other small invertebrates moving across the ground. The warm climate and moderate humidity of its natural habitat should be replicated in captivity for optimal health.

Because of its limited geographic range and popularity in the hobby, Brachypelma hamorii is a protected species in the wild and most specimens available in the hobby are captive bred.

Appearance

The Mexican Red Knee Tarantula is one of the most recognizable tarantulas in the world.

Typical characteristics include:

• deep black body coloration

• vivid red or orange bands at the leg joints

• thick legs and sturdy terrestrial body structure

• impressive contrast between dark and bright colors

After molting, the red knee markings often appear especially vibrant, making freshly molted specimens particularly striking.

Temperament

The Mexican Red Knee Tarantula is widely regarded as one of the most calm and manageable tarantula species. While all tarantulas can display defensive behavior, this species is typically slow moving and tolerant of routine enclosure maintenance.

Like other New World tarantulas, Brachypelma hamorii possesses urticating hairs on the abdomen which it may kick as a defensive mechanism if threatened.

Because of its relaxed temperament and hardy nature, the Mexican Red Knee Tarantula is frequently recommended as an excellent species for beginners.

Enclosure Setup

The Mexican Red Knee Tarantula should be housed in a terrestrial enclosure that provides ample floor space and substrate for burrowing.

Recommended enclosure features include:

• several inches of substrate for digging

• cork bark hide or natural shelter

• moderate humidity

• good ventilation

• a shallow water dish

Providing a naturalistic enclosure allows Brachypelma hamorii to display its normal behaviors in captivity.

Feeding

Like most tarantulas, Brachypelma hamorii feeds primarily on insects such as crickets, roaches, and other feeder insects.

Juveniles may be fed once or twice per week, while adult specimens typically feed every 7–14 days depending on size.

The Mexican Red Knee Tarantula generally has a steady feeding response and adapts well to captive feeding routines.

Molting and Growth

Tarantulas grow through a process known as molting, where they shed their old exoskeleton and emerge slightly larger.

Prior to molting, the spider may refuse food and become less active. After molting, the tarantula should be left undisturbed while its new exoskeleton and fangs harden.

Because Brachypelma hamorii grows slowly, molts occur less frequently as the spider matures.
