What Do Brazilian Black Tarantulas Eat?

Tarantulas are fascinating creatures that can be found in various parts of the world. With their intimidating appearance and reputation, it’s no wonder they captivate the interest of many people. One species that particularly stands out is the Brazilian Black Tarantula (Grammostola pulchra). In this article, we will explore what these intriguing arachnids eat to sustain themselves.

Brazilian Black Tarantulas have a diverse diet consisting mainly of insects, small vertebrates, and even other spiders. As opportunistic predators, they adapt their feeding habits based on availability and opportunity.


Insects make up a significant part of a tarantula’s diet. Brazilian Black Tarantulas will consume crickets, grasshoppers, beetles, moths, butterflies, caterpillars, and various other small insects when given the chance. These eight-legged hunters use their sharp fangs to inject venom into their prey before consuming them.

Small Vertebrates

Despite being primarily insectivorous creatures, Brazilian Black Tarantulas occasionally indulge in small vertebrates such as lizards and rodents. However uncommon this may be in captivity or natural habitats where these tarantulas reside remains uncertain.

Other Spiders

Another interesting aspect of the Brazilian Black Tarantula’s diet is its cannibalistic nature towards smaller spider species. They may prey upon fellow spiders if they come across them during hunting or territorial disputes.

To capture their prey effectively while avoiding potential harm from larger adversaries or poisonous predators like snakes or birds, these tarantulas utilize several hunting techniques:

1. Ambush Hunting: The Brazillian black tarantula waits patiently in its burrow, concealed under the cover of its silk-lined retreat. When an unsuspecting prey comes within reach, it lunges forward with lightning speed to paralyze and devour it.

2. Web Hunting: Although not known for constructing intricate webs like some other spider species, Brazilian Black Tarantulas may employ simple web structures to catch smaller insects or wandering spiders that stumble upon their territory.

3. Pursuit Hunting: In certain situations where opportunities arise, these tarantulas will actively chase down fleeing prey.

To maintain optimal health and growth, Brazilian Black Tarantulas require a balanced diet rich in nutrients. The primary nutritional components include protein, fats, vitamins, minerals, and sufficient hydration.

In captivity or as pets, ensuring a diverse menu is crucial for providing all necessary nutrients. Offering a variety of live insects such as crickets or roaches along with occasional vertebrate feeders like small lizards can help meet their dietary needs effectively.

Brazilian Black Tarantulas have an interesting and varied diet that consists mainly of insects but also includes small vertebrates and sometimes even other spiders. Their hunting techniques are well-adapted to capture prey efficiently without putting themselves at significant risk. By understanding their dietary preferences and providing suitable nutrition when kept as pets or observed in the wild, we can appreciate these fascinating arachnids better while ensuring their wellbeing.
