Greenbottle Blue Tarantula Facts

Chromatopelma cyaneopubescens is an exotic spider native to Venezuela and Columbia.

These beautiful arthropods feed on a varied diet of small insects.

They generally possess a docile temperament, although they can become aggressive when threatened.

An adult Greenbottle Blue Tarantula can breed in captivity given the right environmental conditions.


C. cyaneopubescens are native to the arid regions of northern Venezuela and Aruba.

They’re known to be semi-arboreal, dwelling in dry, rocky, sandy areas with lots of vegetation.

In such habitats, the species is typically found in grasses, tall weeds, trees, and bushes.

Their range extends from Caracas down to the nearby mountain range.

In the wild, Greenbottle Blue Tarantulas typically form dens made of webbing in crevices or hollows in trees.

This helps to protect them from predators and the elements.

The structure of these dens is reinforced with sticks and leaves to create an airtight cocoon that not only serves as a place of shelter but also helps to regulate humidity levels.

During the day, they will wander around their habitat looking for food or finding a mate.


In their natural habitat, Greenbottle Blue Tarantulas primarily feed on a variety of insects.

This includes crickets, grasshoppers, and other small insects.

They have also been observed to eat small rodents such as mice and voles.

These tarantulas prefer to hunt at night when they sense movement, either by scooping them up in their front legs or trapping them with their webbing.


The Greenbottle Blue Tarantula is generally considered a docile spider, and they are usually not aggressive around humans.

While they will often stay still when held and are not considered dangerous, care should be taken when handling them as they can deliver a painful bite if they feel threatened.

Chromatopelma cyaneopubescens should not be handled by children or inexperienced adults.

Owners should also take care when allowing other animals around their tarantula.

These spiders usually avoid conflict, but they may feel threatened if the other animals get too close, leading to possible defensive behavior.

It’s always best to provide them with their own safe, secure space when in the presence of other pets or people.


Chromatopelma cyaneopubescens have a fairly long lifespan, with males typically lasting between 3-4 years and females 12-14 years.

Adult tarantulas reach a maximum size of about 5-6 inches, and since they can remain at this size for their entire lives, their aging process is slower than other animals. 

When these tarantulas reach adulthood, their life cycle starts with courtship.

Males will approach a female tarantula and perform a courtship behavior to determine if she is receptive and ready to mate.

If she is, the pair will mate and lay eggs.

The female will lay between 50–100 eggs, and these eggs will hatch within a few weeks.

After hatching, the young tarantulas will molt several times until they reach adult size. 

Once fully grown, Greenbottle Blue Tarantulas will continue to molt and reproduce, bringing the next generation of tarantulas into the world.

Thus, with their long lifespans, these tarantulas can bring joy to your life for many years to come.


Greenbottle Blue Tarantulas can reproduce through either sexual mating or parthenogenesis.

Typically, mating will occur between a mature male and a female Chromatopelma cyaneopubescens.

Generally, during mating the male will court the female by waving its legs and then climb onto her back to insert the sperm packet.

After mating, the female will lay her eggs which are typically hidden away in a cozy burrow she has created.

Once the eggs have hatched the offspring, on average, will molt once every two to three weeks for the first 12-18 months of life.

As Greenbottle Blue Tarantulas grow, they will molt and shed their outer shells.

This is a necessary part of their lifecycle as they grow and develop.

As they molt, they will replace their old shells with new, larger ones.

With each molt, their bodies become larger, allowing them more mobility, better eyesight, and increased strength.

It is vital to remember not to handle your pet tarantula during this molt, as their skin will be vulnerable and easily damaged.

Chromatopelma cyaneopubescens can also occasionally be found in the wild in the humid tropical forests of South America.

However, if you do choose to collect one from the wild, you should be sure to follow all local laws, only ever collect one tarantula, and handle it with extreme care.

What Do Greenbottle Blue Tarantulas Eat?

When it comes to feeding your Greenbottle Blue Tarantula, you should ensure that they’re receiving the correct nutrition.

They’re typically insectivores, so providing a variety of insects will give them the best chance of thriving. 

Here are some insects that you can feed Chromatopelma cyaneopubescens:

• Crickets
• Mealworms
• Waxworms
• Dubia roaches
• Superworms
• Silkworms
• Zophobas Morio

While providing your tarantula with live prey is usually the best option, you can also supplement their diet with small dead critters as well.

You should also mist their enclosure a few times a week with water, as this will ensure the environment stays appropriately humid and help the insects move more.
