Mexican Red Rump Tarantula Facts

Mexican Red Rump Tarantulas are a species of ground-dwelling spider native to Central America.

They have a gentle temperament, and their small size makes them an excellent choice for beginner arachnid keepers.

Their natural diet consists of live insects; when properly cared for, they can live for several years.

Breeding is possible, although it can be challenging due to the spider’s size and their need for careful environmental control.


Tliltocatl vagans is a species of tarantula native to Mexico and other parts of Central America.

They live in warm, dry climates such as pine forests, desert regions, dry scrubland, and even in urban areas like cities.

Mexican red rump tarantulas are typically found in burrows or under rocks and logs.

They also tend to congregate in areas with sandy or gravelly soils. 

Mexican red rump tarantulas are fossorial (borrowers), so over time they can build intricate systems of tunnels in the ground.


In the wild, Tliltocatl vagans can be found dining on a wide variety of prey.

This includes insects like grasshoppers, crickets, and cockroaches, as well as other small creatures like lizards and frogs.

They will also occasionally feed on carrion (dead animals) and even small mammals if they can find them.

Mexican Red Rump Tarantulas are relentless in pursuit of their meals, allowing them to successfully hunt large prey items like birds. 

When it comes to getting their energy, the tarantulas prefer to munch on protein-rich food first and foremost.

This helps them to stay healthy and grow to their fullest size potential.

They have also been known to consume small amounts of vegetation from time to time, although it is not their preferred food source.


Tliltocatl vagans is a fairly docile species of spider, so they don’t typically respond aggressively to humans.

These spiders are relatively calm and can make great pets for those who take an interest in them.

However, it’s still wise to respect their boundaries and remind yourself that these spiders are wild animals, no matter how “tame” they might seem.

It’s also good to note that these spiders are solitary animals, so they should be kept separate from each other and other animals such as cats or dogs.

These spiders aren’t generally curious about other animal species, but it’s always best to err on the side of caution and keep them away from other pets in your home.


Mexican Red Rump Tarantulas’ life expectancy depends largely on the species’ sex and can range anywhere from five to twenty years.

Males will typically live for around 4 to 5 years and females will live for 18 to 20 years. It isn’t uncommon for females to even live for as long as 40 years.

Generally, they will follow a typical cycle of growth and molting. This can take longer during colder months and be accelerated during warmer months.

Each molt will leave the tarantula larger and more mature until they eventually reach maturity.

As you can tell, Tliltocatl vagans have quite an intricate and varied life cycle.


One of the fascinating behaviors of Mexican Red Rump Tarantulas is their mating ritual.

Males use dance to attract a female before engaging in courtship behaviors, like drumming their feet and waving their pedipalps.

The male will then attempt to mate with the female and, if successful, will deposit his sperm in a web near her oviduct. 

Once fertilized, the female will lay her eggs in a sac of silk and remain close to ensure they are safe and well-supplied with food.

While the mating rituals of T. vagans are quite complex, practicing proper breeding and mating care is key to having successful and healthy spiderlings.

Keeping the right temperature and humidity levels, as well as providing a secure and safe home, is essential for successful breeding.
