Mexican Redknee Tarantula Facts

Brachypelma hamorii is a vibrant species of spider with a lifespan of 7-25 years in the wild, depending on the sex.

They are carnivorous and feed on live insects from their surroundings.

These spiders can breed easily, yet their temperament is usually quite docile and shy which makes handling them relatively easy.

They enjoy a humid climate and prefer to remain in their burrows.


Mexican Redknee Tarantulas are a species of tarantula native to Central America.

They tend to inhabit dry coastal regions, often found in thickets of vegetation and commonly at lower altitudes.

These spiders live in underground burrows, often hiding among tree roots and under rocks.

They prefer warmer environments but their thick hairs provide protection from any extreme temperatures.

They are typically diurnal, meaning they are active during the day and rest at night.

Much of their time is spent hiding in their pockets or sweeping away debris from their webbing.

The Mexican Tarantulas possess numerous colors which helps them blend in among their natural environments.


In their natural habitat, Brachypelma hamorii consume a variety of small insects and invertebrates.

They are particularly fond of moths, flies, and crickets.

While living in the wild, Mexican Redknee Tarantulas may also seek out smaller prey such as beetles, spiders, and slugs.


Mexican Redknee Tarantulas are generally a docile species, making them a good choice for arachnophobes.

While they are not aggressive, they will bite or kick their hair if they feel threatened.

Although their bites are said to be fairly harmless to humans, they can still be quite painful.

It is recommended to refrain from handling them excessively. 

In addition, Brachypelma hamorii can coexist with other animals, such as large reptiles like iguanas and small mammals like mice.

However, their tank should not be shared with other animals, as they can become territorial and fight with one another or even prey upon one another.


Mexican Redknee Tarantulas typically have relatively long lifespans, living for up to many years.

Males will live for as long as 5-10 years and females will live as long as 25-30 years.

Unlike other types of spiders, this species can continue to grow throughout its lifespan.

Of course, there are a range of factors that can affect the life span of any animal, such as diet, environmental stressors, and health concerns.

The life cycle of the Brachypelma hamorii begins with a number of moltings, which is where the spider sheds its skin and grows larger.

During this time, the tarantula will need to have an increased amount of prey, as this helps to fuel their growth.

After reaching a certain size, they will slow down from growing and reach sexual maturity. 


Mexican Redknee Tarantulas are considered solitary animals, meaning they don’t typically live in groups.

In order to reproduce, males must locate and woo females in order to mate.

Courtship rituals occur in order for successful mating to take place, with the male spider arriving at the female’s burrow and presenting her with a “nuptial gift”, which could include a silk-wrapped dead insect.  

If the male is accepted, the female will allow him to approach her and they will enter into a courtship dance.

As the male and female exchange sperm and eggs, the female will build an egg sac, containing hundreds of eggs.

While it takes two to four weeks for the eggs to hatch, the female will stay with the egg sac until the spiderlings emerge.

The tiny spiderlings then stay with their mother for one to two weeks before dissipating into the environment.
