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 (4) (5). 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 (4).
This species produces large silken egg sacs, which may contain up to 300 eggs (4). The spiderlings initially stay with the female and eventually disperse after several weeks to build their own burrows (2). Mexican redrump tarantula males are mature at the age of seven to eight years, while females reach maturity after nine or ten years (4). This spider can reach an impressive age of 25 years in the wild (2).
The Mexican redrump tarantula is nocturnal, meaning it hunts during the night and rests during the day. Like all tarantulas, it is an active hunter, primarily feeding on insects and occasionally killing larger prey such as rodents (2).
