What Are Dimorphic Jumping Spiders?

Dimorphic Jumping Spiders are a species of arachnid with the scientific name of Maevia inclemens, which belong to the Salticidae family.

The term “Dimorphic” refers to their two contrasting colors – one darker than the other – which is one of their most distinctive features.

They can be found in North America and Central America, usually in open areas where there is a lot of vegetation.

What Do Dimorphic Jumping Spiders Look Like?

Maevia inclemens are arachnids that are widely regarded for their unique appearance.

These small spiders typically measure around 5-7mm in length with females measuring slightly larger at 6.5-10mm. They generally have a flat, oval-shaped body.

These jumping spiders have distinctive shades of tan coloring, with some specimens also possessing shades of orange and red.

They have short stubby legs and often have stout little abdomens.

Despite their small size, Dimorphic Jumping Spiders have excellent eyesight and use this to discern potential threats and navigate their environment. 

Moreover, the jumpers have tubercles around their heads that resemble tiny horns.

The purpose of these tubercles has not yet been confirmed, although it’s speculated that this is either a defense mechanism to deter predators, or to help them orient their bodies when navigating. 

Benefits Of Using Dimorphic Jumping Spiders

Dimorphic Jumping Spiders are incredibly beneficial for vivariums due to their natural role as predators in the ecosystem.

These spiders hunt and feed on other pests and insects, making them ideal for controlling pest populations in tanks.

Additionally, their small size and harmless nature make them a safe choice to keep as pets.

Plus, their curious and social behaviors can provide hours of entertainment and joy.

With their bright colors and playful personalities, these spiders are sure to be a memorable addition to any terrarium.

Dimorphic Jumping Spider Facts

Dimorphic Jumping Spiders are bite-sized, furry spiders native to North America.

They are known for their distinctive two-color pattern, playful behavior, and curious nature.

In the wild, they feed mainly on small insects and can live up to a year with proper care.

They have been known to breed in captivity and are great beginner spiders for pet owners.


Maevia inclemens is a species of jumping spider found in the United States and certain parts of Canada.

The spiders are originally from the Nearctic and Neotropical regions, but they have also been found in parts of Europe, Asia, and the Caribbean.

In their natural habitat, Dimorphic Jumping Spiders typically live among leaf litter and rocks, in low vegetation, in trees, and even in boxes, jars, or cans.

The jumping spiders are a terrestrial species and may be found near urban areas and wooded areas such as forests, fields, and yards.

Dimorphic Jumping Spiders will travel great distances searching for food during the day and then return to their homes at night.


Dimorphic Jumping Spiders have a varied diet in their natural habitats.

These spiders feed on small insects, other spiders, and arthropods which they hunt both by sight and through tactile sensing with their forelegs.

These spiders have fast reaction times and are able to use their jumping and web-spinning abilities to capture their prey.

In the wild, they tend to feed on flies, beetles, and moths, and can also feed on small crickets.

In the warmer months, they may switch to a more liquid-based diet and feed on nectar and pollen from flowers. 

In addition to this omnivorous diet, wild Maevia inclemens require a source of moisture for hydration and access to various environments which provide them with plenty of hiding places and objects to hunt.


Dimorphic Jumping Spiders are considered to be quite docile and non-aggressive around humans and traditional pets.

They are also shy and skittish, so it is advised to give them the time and space to adjust to their new environments.

When feeling threatened, these spiders will typically freeze or retreat, rather than attack.

As long as the spider is not disturbed, it should be peaceful around other animals, as well.

They might even get along with smaller pet animals like guinea pigs and hamsters, although it is advised to always have a habitat separated from these types of pet animals. 

The instinct of the Maevia inclemens is to jump if startled, however, so it is highly recommended to take the necessary precautions while handling these spiders.

Grabbing them abruptly could startle them and cause them to jump away, so approaching them slowly and delicately should be your priority when handling them.


The Dimorphic Jumping Spider is an incredible creature that can typically live for a year.

Over the course of its lifespan, your Dimorphic Jumping Spider will molt several times with each stage providing a better understanding of your spider’s age and maturity.

When the spider is born, it already has the ability to jump.

It will molt its first two times in the first five to six weeks of its life.

During this stage, your spider is particularly vulnerable and needs a lot of food and warmth to help it mature.

After its third molt, usually around the sixth to seventh week of life, your spider will have reached its adult size and will no longer be molting. 


Dimorphic Jumping Spiders mate in a unique way compared to other species of spiders.

Unlike many spiders which employ a special type of communication and courtship ritual, Maevia inclemens instead use the dance-like actions of their colorful legs to attract and interact with mates.

Once two mating spiders have found each other, they will do a brief duet at which point the female is ready to lay her fertilized eggs.

Females will construct a silken egg sac in which they will carefully store and secure up to 200 eggs.

The female will then attach the egg sac to the underside of a rock, stick, or other surface.

Once the eggs are hatched, the young spiders are on their own and must learn to hunt and fend for themselves.

Adult Dimorphic Jumping Spiders rarely interact with their offspring, though it is common for the females to practice aggressive mothering if she comes into contact with their young spiders.

Where To Find Dimorphic Jumping Spiders

If you are looking to purchase a Maevia inclemens there are a few options.

The most common place to locate them is online through retailers such as Arachnoboards or Insectnet.

You might also find Dimorphic Jumping Spiders available at pet stores, but availability will vary.

It’s also worth noting that purchasing jumping spiders from reputable breeders is highly recommended to ensure that your spider is healthy and well cared for.

On the other hand, if you are wanting to find one in the wild, then your best bet is to do some research.

These spiders are found fairly frequently in the Pacific Northwest and Midwest United States, so you may want to look there first.

You should also be sure to practice responsible collecting by leaving the spider’s habitat intact and using gloves to handle any spiders.

To identify Maevia inclemens you should look for a bright-colored spider with stripes or mottling on its body.

Dimorphic Jumping Spider Care

Dimorphic Jumping Spiders require a habitat with appropriate temperatures, moisture, and ventilation, as well as certified insect food and occasional treats.

They should be handled gently and interact with their owners frequently.

Caring for your Dimorphic Jumping Spider properly can provide an educational experience and enjoyment.

Tank Requirements

The ideal vivarium type for a Dimorphic Jumping Spider is a tall, glass tank with adequate air circulation.

The tank should be filled with between 2-3 inches of loose terrarium substrate like high-quality soil and moss, with a few pieces of wood or bark to provide additional climbing surfaces.

The tank’s water tray should have a pH between 6.5 and 8.0, a hardness of 200-400 ppm, and a temperature range of 75-85 degrees Fahrenheit.

The enclosure should also have a terrarium light in order to provide the spider with a consistent day/night cycle.

What Do Dimorphic Jumping Spiders Eat?

Feeding Maevia inclemens is an essential part of its care.

These spiders are carnivores and require a varied diet of live foods like small crickets, moths, and mealworms.

Some keepers also feed their spider arthropods like isopods. Be sure to dust the live food with a vitamin and mineral supplement.

If the spider will not eat live foods, you can also provide freeze-dried food or small slices of fruit. In addition, provide a shallow dish of water for your spider to drink from.

Best Tankmates For Dimorphic Jumping Spiders

It is good practice to choose tankmates carefully for a Dimorphic Jumping Spider.

These spiders are relatively solitary animals, so they can feel uncomfortable if they are housed with other spiders and they can even be territorial when sharing their enclosure.

If you want to provide your spider with some companions in its enclosure, you can choose animals that have similar beneficial qualities or those that won’t cause any unnecessary competition for resources.

One great tankmate for a Dimorphic Jumping Spider is a prey insect, such as springtails, mealworms, or small millipedes.

Since Maevia inclemens are active hunters, adding an additional source of food to the enclosure can help keep your spider active and healthy.

Other suitable tankmates can include terrestrial snails and isopods. 

If you plan on keeping multiple jumping spiders in a large tank, remember that they may be territorial, so it is important to monitor the enclosure carefully and separate any aggressive spiders from the group.

Additionally, always remember to research any species before introducing them to an enclosure, to ensure that the species are compatible and to avoid any potential problems.


Caring for Maevia inclemens can be both a rewarding and enjoyable experience.

By following the guidelines outlined in this article, you’ll be able to confidently provide your spider with a safe and enriching environment that they can enjoy and thrive in.
