Back to tarantula species list

Scientific Name: Grammostola pulchra (Mello-Leitão, 1921)

Common Name(s): Brazilian Black Tarantula

Range: Brazil and Uruguay.

Habitat: Grassland and pampas

Experience Level: Beginner/Intermediate

Type: Terrestrial, opportunistic burrower

Size: Leg span up to around 20cm (8″)

Growth rate: Slow

Venom: Mild

range-g-pulchraUrticating hairs: Yes

Temperament: A generally calm and docile species, suitable for beginners though care should be taken due to their large size. They tend to be reluctant to bite and don’t tend to flick hairs as much as many other species making them very desirable for beginners.

Description

It’s not difficult to see where this impressive looking species of tarantula gets its common name – as adults they are jet black with a striking velvety appearance (immature spiders such as the spiderling shown below tend to be brown, taking on their adult colour after several moults). Combined with their striking looks, their impressive size and generally docile and tractable demeanor make them incredibly desirable to enthusiasts, and suitable for beginner tarantula keepers. A ban on export from Brazil however, combined with their slow rate of growth, means that adult specimens tend to be rather expensive.

Keeping G. Pulchripes in Captivity


brazilian-black-slingG. pulchra
 is a terrestrial species which will often burrow if given the opportunity, so a decent depth of substrate (of several inches) should be provided, though many specimens will tend to take up residence in any type of hie provided.

For general care requirements, read the basic guide to tarantula care page which gives a good overview of tarantula husbandry.

An adult Brazilian Black will require a large enclosure such as a large plastic or acrylic tank, or a 10 – 15 gallon aquarium with a suitable top.  Provide a deep, fairly dry substrate (4 – 5 inches of coconut coir, or dry potting soil), plenty of ventilation, and a secure lid.  A large piece of cork bark will serve as a suitable hiding place (half a coconut shell won’t be large enough for an adult!), and a large shallow water dish should be provided at one end of the enclosure which can be overfilled to dampen the substrate slightly at one end of the tank.  No special care requirements are necessary.

A diet of large crickets, cockroaches and locusts should be provided.  But as with all tarantulas, feed prey items of a suitable size (no larger than the spider’s abdomen).

Like with G. pulchripes, one of the reasons for G.Pulchra being so sought after for some people is their tolerance to being handled.  It’s true that this species in general tend to be docile and fairly tolerant to handling, but remember that every individual tarantula is different.  Though they don’t tend to bite and have relatively mild venom, care should be taken since the fangs of an adult are large enough to do mechanical damage.  As always, handling is at the individual’s own risk and should be avoided if possible.

Grammostola pulchripes – Chaco Golden Knee Tarantula Caresheet

Grammostola pulchripes

Back to tarantula species list

Scientific Name: Grammostola pulchripes (Simon 1892)
(previously Grammostola aureostriata)

Common Name(s): Chaco Golden Knee

Range: The Chaco region of Argentina, and the Grand Chaco region west of the Paraguay river.

Habitat: Grassland and scrub

Experience Level: Beginner/Intermediate

Type: Terrestrial, opportunistic burrower

Size: Leg span up to around 20cm (8″)

Growth rate: Slow/Medium

Venom: Mild

Urticating hairs: Yes

Temperament: A generally calm and docile species, suitable for beginners though care should be taken due to their large size.

Description

Deriving its common name from the golden stripe on each knee (its former latin name was Aureostriata, meaning “golden striped”) this beautiful species grows to an impressive size, yet tends to be calm and docile.  They are a new world terrestrial tarantula, and opportunistic burrower.   They are reported to be one of the fastest growing species in the Grammostola genus, and they also tend to be quite active, though they tend to prefer using an existing hide rather than digging a burrow.  Combined with their striking looks, their generally calm nature and impressive size, and the fact that they tend not to be shy of staying out on display makes them a desirable species both for the beginner tarantula keeper, and for more experienced keepers looking to add a new impressive spider to their collection.

G. pulchripes is often misidentified as Eupalaestrus campestratus (the Pink Zebra Tarantula) which live in the same region.  Chacos coming from Argentina are less hairy than specimens from the Paraguay population, and it’s thought that there may be a third population in Uraguay.

Keeping G. Pulchripes in Captivity

Chaco Golden Knee copyright Flickr user Óscar MéndezG. Pulchripes, as already mentioned, makes an excellent choice as a first tarantula species.  They are generally low maintenance with no special care requirements, and will thrive given the standard husbandry for generally arid, terrestrial species so long as they are given an enlcosure large enough for such a big tarantula.

For general care requirements, read the basic guide to tarantula care page which gives a good overview of tarantula husbandry.

An adult Chaco Golden Knee will require a large enclosure such as a large plastic or acrylic tank, or a 10 – 15 gallon aquarium with a suitable top.  Provide a deep, fairly dry substrate (4 – 5 inches of coconut coir, or dry potting soil), plenty of ventilation, and a secure lid.  A large piece of cork bark will serve as a suitable hiding place (half a coconut shell won’t be large enough for an adult!), and a large shallow water dish should be provided at one end of the enclosure which can be overfilled to dampen the substrate slightly at one end of the tank.

A diet of large crickets, cockroaches and locusts is ideal.  But as with all tarantulas, feed prey items of a suitable size – no larger than the spider’s abdomen.

One of the attractions of G. pulchripes for some people is their tolerance to being handled.  It’s true that this species in general tend to be docile and fairly tolerant to handling, but remember that every individual tarantula is different and that this species can be fast.  While its venom is mild and this species rarely bites, the fangs on a spider this large are more than capable of doing real damage.  At the same time, a fall from even a very small height would easily kill a tarantula of this weight so handle carefully, only if you understand and accept the risks to both yourself and your tarantula.
