Brachypelma vagans is a species of tarantula known commonly as the Mexican red rump or Mexican black velvet. It ranges predominantly in Mexico, 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 scrubland 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.

Like many Tarantula’s, Brachypelma Vano is a grain spider and survives most of it in the broods in most life. Mexican red ramp spiders hide deeper in its boats during the day, however, at night the spider is waiting for any form of prey to stand at the end of the boat.


The Mexican redrump tarantula is a fossorial species, living underground and digging complex burrows, which can have several chambers and be up to 45 centimetres deep. The diameter of the burrow entrance usually reflects the body size of the inhabitant, so juvenile burrows are smaller than the burrow of fully grown adults.

This species produces large silken egg sacs, which may contain up to 300 eggs. The spiderlings initially stay with the female and eventually disperse after several weeks to build their own burrows. Mexican redrump tarantula males are mature at the age of seven to eight years, while females reach maturity after nine or ten years. This spider can reach an impressive age of 25 years in the wild.


I read that they grow to six inches (15.24cm). After ten years my girls are a solid six inches (15.24cm).


The Mexican redrump tarantula, in contrast to many other tarantulas, tends to avoid forests and primarily lives in open areas, such as forest clearings and back gardens. It has also been found in citrus groves.
