Natural History
In the wild, Pamphobeteus species inhabit tropical forests where they construct burrows beneath roots, rocks, and fallen debris. These underground retreats provide protection from predators and help regulate temperature and humidity.
The Colombian Purple Bloom Birdeater Tarantula typically spends daylight hours hidden within its burrow and becomes active at night when it emerges to hunt insects and other small prey moving across the forest floor.
Replicating warm temperatures and moderate to high humidity in captivity helps maintain healthy conditions for this large tropical species.

Typical characteristics include:
-
deep brown to black base coloration
-
shimmering purple iridescence visible under lighting
-
thick legs and powerful terrestrial body structure

Temperament
Like many Pamphobeteus species, this tarantula has a strong feeding response and alert temperament. When disturbed, it may retreat into its burrow or kick urticating hairs as a defensive mechanism.
As a New World tarantula, the Colombian Purple Bloom Birdeater Tarantula possesses urticating hairs which it may use if threatened.
Because of its size and energetic behavior, this species is typically recommended for hobbyists with some tarantula experience.
Enclosure Setup
The Colombian Purple Bloom Birdeater Tarantula should be housed in a terrestrial enclosure that provides ample space and deep substrate.
Recommended enclosure features include:
-
several inches of substrate for burrowing
-
cork bark or natural hide
-
moderate to high humidity
-
good ventilation
-
a shallow water dish
Providing a naturalistic enclosure setup allows this species to display normal burrowing and hunting behavior.
Feeding
Like most tarantulas, Pamphobeteus species feed primarily on insects such as:
Juveniles may be fed once or twice per week, while adults typically feed every 7–10 days depending on size.
The Colombian Purple Bloom Birdeater Tarantula is well known for its powerful feeding response and quick strike.
Molting and Growth
Tarantulas grow through molting, where they shed their old exoskeleton and emerge 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.
As Pamphobeteus sp. “Machala” matures, the shimmering purple coloration often becomes more noticeable.
