The Chaco golden knee tarantula is a large variety of spider. It is black or dark brown in color and has yellow markings around the knee joints.
Adult Chaco golden knee tarantulas have a 7” legspan.
In the wild, tarantulas eat insects and other arthropods. Cosley Zoo’s tarantula is fed crickets and mealworms.
Mating can occur any time of year. After mating, the female lays 100-500 eggs in a silk capsule. The young hatch about six weeks later.
This type of tarantula is native to Argentina, Uruguay, and Brazil. It is a burrowing species.
In human care, males live to be 5-10 years old, while females live 20-25 years. Little is known about the lifespan of wild tarantulas.
Spiders make up an important part of the food chain by helping to control populations of insects, including some that prey on farmers’ crops.
