Brachypelma auratum
A tarantula endemic to the Mexican states of Guerrero and Michoacan. It resembles the Mexican red knee but is darker, and the red striations on its patellae suggest a flame, hence the name flame knee.
The Mexican flame knee (Brachypelma auratum) is a theraphosid tarantula endemic to the Mexican states of Guerrero and Michoacan. It looks much like B. smithi, the classic Mexican red knee, but is darker overall, with finer, sharper red striations on the patellae. Those markings suggest a flame and give the spider its common name. Because it is so similar to B. smithi it was not recognised as a distinct species until 1992. In the wild it has been found living communally with a small frog, Eleutherodactylus occidentalis. Brachypelma species are known as docile tarantulas that are easy to keep in a terrarium, and the females are long-lived: in the wild they take 9-10 years to mature and can then live about another ten. Collection for the pet trade and habitat destruction have put every species in the genus on CITES Appendix II.
