Hyllus diardi Facts

Hyllus diardi are active hunters that have an average lifespan of a few years.

This species of spider is also known for its impressive defensive capabilities.

H. diardi can raise their forelimbs and display a large pair of yellow-tinted fangs that open and close to ward off predators.

They can also run away quickly or enter a defensive posture to deter any perceived threats.

They are fairly docile and their natural diet consists of small insects, arachnids, and spiders.

Breeding these spiders can be tricky due to their difficulty to distinguish between males and females, but with patience and attention, it can be done successfully.


Hyllus diardi is a medium to large-sized jumping spider found in the tropical rainforests of Africa and Madagascar.

This species prefers habitats with well-developed forests, especially wet forests in lowlands and mountains.

They may live in trees, under stones, and in leaf litter among other places.

These spiders have well-developed eyes that are adapted for hunting and detecting movement from relatively far away.  


The Heavy Jumping Spider is an opportunistic hunter in the wild, meaning they will eat whatever is available and meets their nutritional needs.

In nature, they are known to dine on insects, worms, and arachnids such as other spiders.


When it comes to temperament, Heavy Jumping spiders are typically quite laid-back and calm when around humans.

Because they’re used to warmer climates, they often move slowly and cautiously due to the climate difference.

They don’t generally like to be handled, so it’s important to just observe and enjoy the information that you can gain from them without trying to physically interact.

They are also non-aggressive to other animals, which can make owning multiple species within the same enclosure possible.

Since they lack venom strong enough to affect humans, they are considered to be a safe pet to have around small children.


The average lifespan of Hyllus diardi is anywhere between 1-3 years in captivity.

This species typically takes a full year to mature, with females living longer than males.

During this time, the species matures through a number of phases: egg, spiderling, subadult, and adult.

After hatching, the young spider takes between six and seven weeks to reach the adult stage.

As it grows, the spider will require more food and therefore it is recommended to feed the spider according to its size.

Sometimes, the spider may stop eating for several days, usually during a molting process – but this behavior is natural and should not be of concern. 


The mating and reproduction process of Hyllus diardi spiders is fascinating and complicated.

While males typically live for a little over a year, the lifespan of female H. diardi is considerably longer at around two to three years.

To initiate the process, the male will perform a courtship ritual to attract the female.

If successful, the mating ritual can last anywhere from half an hour to several hours.

When a female spider is ready to reproduce she will make a unique web-like cocoon to store her eggs.

Once she lays her eggs and the web is complete, it will be kept in a secure area and can take several weeks for the eggs to hatch.

When hatching, the baby spiders will immediately search for shelter to hide away from potential predators.
