Species: B. vagans
Brachypelma vagans is a species of tarantula known commonly as the Mexican red rump. It has been proposed that the species should be moved to the genus Tliltocatl. It ranges predominantly in Mexico (including the Yucatán Peninsula), but is also found in Central America. They are terrestrial, burrowing spiders. The reason for the name red rump is because of its distinctive red hairs on its abdomen. Like most tarantulas, they will eat anything they can overpower, which is usually insects, but small lizards and rodents may also be consumed. They can grow up to a solid 6.5 inch leg span, with males typically being smaller and thinner than the females. They prefer shrubland habitats.
In 1996, Brachypelma vagans was discovered in the wild in St. Lucie County, Florida. It is now considered an established non-native species in that state, where it is thought to have been introduced through either accidental or intentional releases of specimens imported via the pet trade, although their numbers have been dwindling due to many B. vagans eating insects poisoned by pesticides.
