The Chaco Golden Knee Tarantula, scientifically known as Grammostola pulchripes, is a magnificent and popular species of tarantula native to the Chaco region of Argentina, Paraguay, and Bolivia. Revered for its stunning colouration and docile nature, this tarantula species has become a favorite among both beginners and experienced tarantula keepers. The Chaco Golden Knee Tarantula is named for the distinctive golden bands on its legs, which contrast beautifully with its dark brown to black body. As juveniles, they exhibit a darker overall coloration, gradually transitioning to the golden hue as they mature. The mature females can reach a leg span of 6 to 7 inches (15 to 18 cm), while the males tend to be slightly smaller. Grammostola pulchripes are known for their docile nature and are considered one of the more laid-back tarantula species, making them an excellent choice for tarantula enthusiasts seeking a manageable and friendly pet. In their natural habitat, this tarantula inhabits dry grasslands and scrublands. They are terrestrial in nature and create intricate burrows to retreat to when they feel the need for security. These burrows are typically lined with silk and serve as both a safe haven and a hunting ground for the tarantula. They primarily feed on insects, small arthropods, and occasionally small vertebrates. When housing the Chaco Golden Knee Tarantula, providing a spacious enclosure with plenty of substrate for burrowing is crucial. They require a moderately warm and dry environment, with temperatures ranging from 75 to 85°F (24 to 29°C). It’s important to maintain appropriate humidity levels by lightly misting the enclosure rather than creating a consistently damp environment.
