Green Jumping Spider Facts

Mopsus mormon is a small, arboreal spider from Australia, with an average lifespan of a few years.

They have an impressive jumping ability that allows them to hunt for their primary diet of small insects and spiders in the wild.

They are an active, sociable species that tend to breed in the spring, and they can make an active and friendly pet if given the right care and environment.


Green Jumping Spiders are arachnids originally discovered in Australia and New Guinea.

In their native habitats, you can usually find Mopsus mormon in tropical rainforests and sparsely wooded forests.

They prefer areas with plenty of trees and foliage where they can spin webs and hide away if necessary.

During the day, Green Jumping Spiders tend to stay high in the foliage to stay out of the reach of predators.

At night, they come out of their hiding places to look for food, either actively hunting or sitting and waiting on their webs.

As such, they prefer a humid climate, as the moisture helps to preserve their webs and makes hunting prey easier.


Mormon Jumping Spiders in their natural habitat primarily eat insects and other small invertebrates.

Their diet includes flies, beetles, moths, caterpillars, cricket, spiders, and other small prey.

They use their powerful jumping skills and built-in venom to catch their prey.

In the wild, these spiders will hunt at night and will eat their prey alive. 


Green Jumping Spiders are generally docile and shy creatures around humans.

As they are generally solitary animals, they will rarely show aggression to potential predators and rarely bite humans, even if they feel threatened.

Because of their small size, they do not require much handling, and can generally stay in their enclosure without having to be taken out.

That being said, they are quite active animals and may become scared or struggle if handled too harshly.

It is important to be gentle and patient when handling your Green Jumper. 

When kept in the same enclosure as other Green Jumping Spiders, they may have the tendency to fight, so it is not suggested that they live with other spiders.

When it comes to other animals, such as other insects, small amphibians, or other arthropods, it is essential to research and ensures compatibility before introducing them to the same enclosure as your spider.

Many of these creatures may prey on or otherwise irritate or stress out your pet, not to mention the risk of transmitting diseases or parasites to the spider.


Mopsus mormon is known to live an average of 12 to 24 months.

In ideal conditions, they may live even longer.

Like many spiders, they spend the first portion of their adult lives in the late molt stage when they become sexually mature.

During this time, they build silken retreats, mate, and eventually lay eggs in late summer.

After hatching, the spiderlings take about 2-3 months to reach maturity, whereupon they then begin their own adult life cycle.


Green Jumping Spiders have elaborate mating rituals and they will often perform a complex courtship mating dance.

The male will display his colorful side, flicking his front legs or tapping the air with his chelicerae.

If the female is interested, she will signal her interest by waving her front legs in a reciprocating manner.

the wild, when the female fancies the male, the two will mate and the male will then leave.

After the mating takes place, the female will deposit her eggs in a safe location and will cover them with a warm substrate such as dried leaf litter or soil.

The eggs will remain safe from predators until they hatch, usually two or three weeks later.

The hatchlings look like tiny adult spiders, but they are not yet able to hunt, and they rely on camouflage and other protective strategies to survive.

After a few weeks, they will venture out and start to hunt and feed on their own until they reach adulthood.

Where To Find Green Jumping Spiders

If you’re interested in obtaining a Mopsus mormon of your own as a pet, there are a few different options.

The most popular way to find them is to order them online from a reputable breeder.

The ideal temperature range is between 71-80°F and the pH and hardness levels for water provided should be maintained between 6.5 and 7.0.

The terrarium substrate should be kept at least 2 inches deep with a mix of moss, bark, leaves, and/or cork for climbing.

Terrarium lighting should be kept to a minimum, although some owners may opt to use a UVB-emitting low-wattage bulb – only if necessary.

These animals share the same temperature, humidity, and dietary needs for jumping spiders, so they can be kept with the spider without putting it in any danger.

These slow-moving counterparts also provide movement stimulation for the jumping spider, encouraging it to be active and explore its environment.

Moths, crickets, and mealworms can also be fed to the jumping spider as a nutritious meal.
