Tlitocatl vagans – Mexican Red Rump Tarantula

Tlitocatl vagans, commonly known as the Mexican Red Rump Tarantula, is a striking New World tarantula species prized for its deep black body and contrasting red hairs on the abdomen. Native to Mexico and parts of Central America, this terrestrial tarantula inhabits scrublands, tropical forests, and burrow-rich grasslands where it spends much of its life underground.

Appearance and Behavior

The Mexican Red Rump Tarantula typically displays a velvety black carapace and legs, with a distinctive reddish to burgundy patch of hairs on the abdomen that gives the species its common name. Adults reach a leg span of around 12–15cm, making them a medium to large tarantula. This species is generally calm but can be defensive, using clouds of urticating hairs and threat postures as primary means of protection when disturbed.

As a nocturnal hunter, Tlitocatl vagans spends much of the day hidden in burrows or retreats, emerging at night to feed on insects and other small invertebrates. Its robust build, hardy nature, and relatively predictable behaviour make the Mexican Red Rump Tarantula a popular choice among beginner and experienced tarantula enthusiasts alike.

Care and Captive Husbandry

In captivity, the Mexican Red Rump Tarantula thrives in a well-ventilated enclosure with ample substrate for burrowing and webbing. A secure hide, shallow water dish, and moderate humidity levels help replicate its natural environment. This species is known for its longevity, with females often living well over a decade under proper care, making it a long-term commitment in any tarantula collection.
