Brazilian Black Tarantula Facts

The Brazilian Black Tarantula is an attractive terrestrial species native to Brazil.

With proper care, these arachnids can live for many decades in captivity and reach up to several inches in length.

They are mostly docile and mainly feed on crickets, waxworms, and various insects.

Breeding is possible, but it often proves difficult for first-time tarantula keepers.


As mentioned briefly earlier, Grammostola pulchra is a species of tarantula native to the subtropical climate of Brazil.

These spiders inhabit humid, tropical forests up to an elevation of 2,500 feet with a large amount of cover and decaying leaf litter for them to hide and forage in.

Brazilian Black Tarantulas spend most of their time underground, emerging at night to hunt for their prey.


In the wild, Grammostola pulchra feed on a variety of insects and arthropods. They mainly forage at night for their food.

When they spot an insect, they quickly ambush them and inject them with venom to immobilize them.

Some of their favorite food sources include crickets, grasshoppers, and other large insects.

They will also scavenge dead and decaying animals, as well as consume fruit and other plant material on rare occasions.

It is good to note that these tarantulas can go several weeks without eating, so when feeding in captivity, it is best to do so once every two weeks.


The Brazilian Black Tarantula is a docile species that prefers to keep to itself.

While these tarantulas can be quite skittish, they tend to be very slow to bite, even when threatened.

They are timid and will likely choose to run away rather than attack.

As long as you handle them gently and respectfully, the large spider will not be likely to bite or cause any harm.

That said, it’s a good habit to use extreme caution when handling them as an unexpected scare or sudden movement could agitate them and cause them to bite in self-defense.

In addition to humans, Grammostola pulchra should not be kept with other animals.

This species of tarantula has an impressive defensive posture and is capable of quickly attacking other animals that enter its space.

Therefore, it is not recommended that you house other animals or insects alongside this species in captivity.


The average lifespan of Grammostola pulchra is approximately five to ten years with females living as long as twenty to thirty years.

These tarantulas generally take at least three years to reach their full adult size.

Brazilian Black Tarantulas take anywhere from two to three months to complete their life cycle from egg to adult.

Females lay their eggs in a sac made of dense silk before attaching it to a wall, tree, or ground.

The eggs remain dormant until the spiderlings hatch, usually when temperatures are warm in the late spring or early summer.

Once hatched, the spiderlings then molt several times throughout the next few months until they reach adulthood.


Mating and reproduction in Brazilian Black Tarantulas occur primarily during the warmer months of the year.

The male tarantula will detect the scent of a receptive female and will pursue her.

At this point, a courtship ritual may begin, during which the male will extend his pedipalps briefly toward the female.

Once the female allows the male to mount her, mating will begin.

Following mating, the female will form an egg sac and lay up to 150 eggs.

After the eggs have hatched, the spiderlings will remain in the web and molt several times, over the course of a few weeks, before dispersing into the wild.

Where To Find Brazilian Black Tarantulas

For those looking to find Grammostola pulchra in the wild, there are a few places you may be able to locate one.

These tarantulas can be primarily found in southern Brazil near the La Plata region.

However, since they prefer to stay hidden, it can be quite a challenge to find them in the wild. 

If you don’t feel up to the challenge, you can always purchase one from a pet shop, reptile expo, or through an online breeder.

Before purchasing, make sure the vendor is reputable and has a good record of supplying healthy and ethically sourced spiders.

There are also a number of online spider forums which can connect you with local breeders.

Brazilian Black Tarantula Care

Caring for Brazilian Black Tarantulas requires providing them with suitable housing, correct temperature and humidity levels, a nutritious diet, and occasional handling.

Additional supplies, such as a shallow water dish or terrarium substrate for burrowing, will also be needed to provide an appropriate habitat for the tarantula.

Health concerns, such as mites and other parasites, should be monitored regularly and addressed as needed.

Tank Requirements

An ideal tank setup for Grammostola pulchra should have a 15-gallon terrarium or paludarium with a secure lid or screened cover.

A humid hide should be provided, as Brazilian spiders prefer humid environments.

The substrate should be earthy, as Brazilian Black Tarantulas dig shallow burrows, and a shallow water dish will also be required.

The optimal temperature range for these spiders is 70-80° F, and they prefer a pH and hardness level between 6.5-7.5.

Additionally, these spiders like a dark and quiet environment, so timed terrarium lighting is necessary, as day/night cycles help their biological clocks function.

What Do Brazilian Black Tarantulas Eat?

Feeding Grammostola pulchra can be fairly easy as long as you have the right diet and variety to offer.

In the wild, they primarily feed on insects, although they can also feed on small mammals, amphibians, and other invertebrates in certain circumstances.

It is vital to note that, since they are basically ambush predators, they will wait until an animal enters their range or until they sense the presence of food before they will go out of their way to feed.

Here are some suggestions of what you can feed Brazilian Black Tarantulas in captivity:

• Crickets
• Mealworms
• Superworms
• Waxworms
• Small Pinky Mice
• Cockroaches
• Earthworms
• Fish
• Frogs

Make sure that all food items are gut loaded and dusted with a calcium or mineral supplement, depending on your tarantula’s needs.
