Benefits Of Using Heavy-bodied Jumpers

Hyllus semicupreus make great additions to vivariums.

These arboreal spiders are not particularly fast, meaning they are suitable for even the most inexperienced hobbyists.

They are also relatively easy to care for, needing basic web-building supplies, a well-regulated environment, and an occasional dusting with calcium and vitamin powder for a complete diet.

Heavy-bodied Jumpers can also help keep tanks clean as they are clean eaters and do not scavenge, meaning they won’t bring in any potential contaminants.

They are also quite docile and gentle so that they won’t frighten or injure other tank mates.

As a result, Heavy-bodied Jumpers make the perfect companion to any enclosure.

Hyllus semicupreus Facts

The Heavy-bodied Jumper is a species of spider native to Southeast Asia.

They are known for their large, black-and-tan bodies and diet of invertebrates, fruit, and nectar.

These spiders are known to be docile and relatively easy to handle, with a lifespan of several years.

Breeding success is often hard to come by, partly due to the fact that females tend to live much longer than males.


Hyllus semicupreus is a species of spider native to Southeast Asian countries such as Thailand and Indonesia.

The H. semicupreus is a reclusive species and prefers to live undisturbed in humid environments that typically have a temperature range between 70 to 80 degrees Fahrenheit.

In their natural habitat, they are most often found living in tree trunks, rock crevices, and foliage.

They have also been known to inhabit caves, but typically only when other populations of the species are nearby.

The Hyllus semicupreus is preyed upon by other predatory spiders, yet benefits from improved habitat structure in those areas that experience frequent rainfall.

The spider’s diet consists of small insects and other arachnids, and their predatory behavior helps keep populations of other harmful insects in check.


Heavy-bodied Jumpers eat a diet that suits their predatory lifestyle in their natural habitat.

These mini spiders feed mainly on insects such as grasshoppers, moths, crickets, and other ground-feeding arthropods.

They also eat small lizards and other vertebrates.


The Heavy-bodied Jumper is a friendly, curious species when around humans.

They are known to be calm and docile, making them a suitable choice for beginner and experienced owners.

With regular handling, they become quite comfortable with people, often even becoming sociable.

However, as with any species, handling should be done with careful observation of their behavior. 

Hyllus semicupreus may get aggressive towards other jumpers in the same enclosure and may even show signs of aggression towards other animals, especially if they are in an environment that is too overcrowded.

Therefore, it is recommended to house them with only those of the same species and to provide enough space for them to live comfortably.

If you plan to house them with other animals of different species, always monitor the interactions as Heavy-bodied jumpers can become territorial.


Hyllus semicupreus are short-lived arachnids, typically living only one to two years in captivity.

In the wild, the average lifespan is believed to be much shorter, as this species can suffer from drought and predation.

Their life-cycle consists of a few main stages: egg, juvenile, and then adult. Eggs are laid in the soil and need a humid environment to hatch.

The spiderlings grow for a few weeks, then form into young juveniles which then develops into an adult.

Hyllus semicupreus typically completes one full life cycle in eight to twelve weeks.

Adults often mate before dying, and the female will lay up to 20 eggs at a time in the soil.

The eggs usually hatch within seven to ten days and the cycle begins again. 

The Heavy-bodied Jumper’s life span and overall developmental timeline can be easily altered by various environmental factors like temperature, humidity, food sources, and overcrowding.

It is important to provide an optimal habitat to ensure the spider’s health, longevity, and successful reproduction.


The mating habits of Hyllus semicupreus can be complex and hard to observe.

This bond between the male and female is maintained by participating in occasional mating rituals and sharing food.

When the pair is ready to reproduce, the female will create a webbing in her chosen location and the male will follow. 

The female will then lay her eggs in the webbing and the pair will guard them until they are mature enough to survive on their own.

They tend to reproduce multiple times a year with clutches ranging from several to dozens of eggs, although this varies somewhat depending on the particular female.

The male will protect the eggs from predators and adjust their webbing as necessary to maintain a safe environment for the eggs to incubate.
