Males average 5-6 years, while females can live much longer – over 20 years in captivity. Little is known about how long they might live in the wild.
Native to the Chaco region of South America including parts of Argentina, Bolivia, Uruguay, Paraguay and Brazil with a climate of warm dry winters and wet summers. They are ground-dwelling in the grasslands and are a burrowing species.
Black or dark brown in color with yellow (or gold) markings over the “knee” joints, this is one of the larger and most docile species of tarantula. Known to be gentle and tolerant, the Chaco Golden Knee can grow up to 20-22 cm (up to 7-9 inches!) legspan. After mating the female lays 100-500 eggs in a silk capsule, which then hatch 6 weeks later as spiderlings. Tarantulas, like other spiders, have an external skeleton (exoskeleton) that protects and supports their bodies.
They eat insects and other invertebrates and arthropods after injecting digestive juices through their two hollow fangs into the prey and then sucking up the liquified contents. Charlie is fed mealworms, dubia roaches and crickets.
Spiders play an important role in the food chain helping to control populations of insects. Luckily, this species is considered of “least concern” by the IUCN (International Union for Conservation of Nature).
