Natural History
In the wild, Megaphobema mesomelas inhabits humid tropical regions where it constructs burrows beneath roots, rocks, and forest debris. These burrows provide protection from predators and help regulate temperature and humidity.

dark brown to black body coloration

thick legs and robust body structure

Temperament
Megalophobema species are known for their unique defensive behavior, often performing rapid spinning or striking movements with their rear legs when threatened.
Like other New World tarantulas, the Colombian Giant Red Leg Tarantula possesses urticating hairs which it may kick as a defensive mechanism.
Because of its energetic defensive displays, this species is best suited for hobbyists with some experience keeping tarantulas.
Enclosure Setup
The Colombian Giant Red Leg Tarantula should be housed in a terrestrial enclosure that allows for natural burrowing behavior.
Recommended enclosure features include:
-
several inches of substrate for digging
-
cork bark hide or natural shelter
-
moderate to high humidity
-
good ventilation
-
a shallow water dish
Providing adequate substrate allows the spider to construct shallow burrows similar to those found in its natural environment.
Feeding
Like most tarantulas, Megaphobema mesomelas feeds primarily on insects such as:
-
crickets
-
roaches
-
other appropriately sized feeder insects
Juveniles may be fed once or twice per week, while adult tarantulas typically feed every 7–14 days depending on size.
The Colombian Giant Red Leg Tarantula generally displays a strong feeding response when prey is introduced.
Molting and Growth
Tarantulas grow through a process known as molting, where they shed their old exoskeleton and emerge slightly larger.
Before 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 Megaphobema mesomelas matures, its coloration and size become more impressive.
