Jumping spiders, belonging to the Salticidae family, are a fascinating group of arachnids known for their unique hunting methods and remarkable jumping abilities. These spiders, with their distinct appearance and behaviors, have captivated the interest of both arachnid enthusiasts and researchers alike. This article delves into the intricacies of the jumping spider size chart, offering insights into their varied sizes and how these measurements play a pivotal role in their overall well-being.
Understanding the size of jumping spiders is crucial, not only for proper identification but also for providing appropriate care and habitat setup.
Overview of Jumping Spiders
Jumping spiders are distinguished by their compact bodies and short, robust legs, which are well-adapted for their characteristic leaps. They possess large, forward-facing eyes that provide them with excellent binocular vision, a trait essential for accurately gauging distances during their jumps.
Unlike other spiders that rely on webs for capturing prey, jumping spiders are active hunters, using their vision and agility to stalk and pounce on their targets.
Distribution and Habitat
The Salticidae family, with over 6,000 species, is widespread across various continents, thriving in diverse environments ranging from tropical rainforests to arid deserts. These adaptable creatures are found in regions as varied as the dense forests of Southeast Asia to the urban landscapes of North America.
Their habitats are as diverse as their species, with some preferring the leaf litter on the forest floor, while others are at home in the foliage of trees or even within human dwellings.
In the following sections, we will explore the size variations among different jumping spider species, providing a comprehensive size chart for reference. This information is not only vital for those looking to identify these spiders but also for individuals interested in their care and conservation.

In the next sections, we will delve deeper into the life cycle, habitat preferences, and care requirements of these fascinating arachnids.
Growth Stages and Size Development
Jumping spiders undergo several developmental stages, known as instars, from hatching to adulthood. Each instar is marked by a molt, where the spider sheds its exoskeleton to grow.
Instar Stages and Size Development
1. Egg Stage: The beginning of life, where the spider is enclosed in a protective egg sac.
2. First Instar (Spiderling): Upon hatching, spiderlings are tiny, often just a few millimeters in length. They primarily consume their yolk sac for nutrition.
3. Subsequent Instars: With each molt, the spiderling grows in size. The number of instars varies among species, but typically ranges from 5 to 10 stages.
4. Adult Stage: Full maturity is reached after the final molt. Adult sizes can vary significantly based on species, as detailed in the size chart.
Size Variation Between Genders
Males vs. Females: Generally, female jumping spiders are larger and bulkier than their male counterparts. This size difference is often noticeable in adult spiders and can be a key factor in gender identification.
Care Based on Size
Housing and Enclosure Recommendations
- Small to Medium Spiders (up to 10 mm): Smaller enclosures, such as modified plastic containers with adequate ventilation, are suitable.
- Large Spiders (10 mm and above): Larger species require more space to move and jump. Terrariums or larger enclosures with dimensions proportional to the spider’s size are recommended.
Feeding Guidelines According to Spider Size
- Small Spiderlings: Micro-prey such as fruit flies or tiny insects.
- Juveniles and Adults: As they grow, their diet can include larger insects like crickets, flies, spider mites, or mealworms. The prey size should be appropriate to the spider’s size, usually not exceeding the spider’s body length.
Importance of Temperature and Lighting
- Temperature: A range of 70-85°F (21-29°C) is ideal for most species. Temperature gradients can be beneficial.
- Lighting: Bright, indirect light mimics their natural environment. Avoid direct sunlight, which can overheat the enclosure.
Common Myths and Misconceptions
Aggression: Contrary to popular belief, jumping spiders are not aggressive towards humans. They are curious and may approach out of interest but rarely bite unless threatened.
Venom: While they are venomous, their venom is not harmful to humans except in rare cases of allergic reactions.
Clarifying Misconceptions About Their Size
Size Exaggeration: Often, people assume jumping spiders are larger than they actually are due to their prominent features and jumping ability.
Size and Danger: Larger size in jumping spiders does not equate to increased danger. In fact, their behavior and interaction with humans remain consistent across different sizes.
In the next sections, we will explore the interaction and handling of jumping spiders, along with their health and longevity, providing a comprehensive understanding of these captivating creatures.
Interaction and Handling
Interacting with jumping spiders can be a rewarding experience, but it requires understanding and respect for their nature.
Handling Based on Size and Species
Small Species: Due to their delicate nature, it’s often best to observe rather than handle. If necessary, gently coax them onto a soft-bristled brush or leaf.
Larger Species: Larger jumping spiders like Phidippus regius can be more easily and safely handled. Allow them to crawl onto your hand of their own accord.
Safety Tips and Best Practices
- Gentle Handling: Always use slow and gentle movements to avoid startling the spider.
- Environmental Awareness: Handle spiders in a safe, enclosed area to prevent escape.
- Hygiene: Wash hands before and after handling to prevent the transfer of harmful oils or substances.
Health and Longevity
The size of a jumping spider can be an indicator of its health status. A well-fed and healthy spider typically grows to the size expected for its species and age.
Average Lifespan in Relation to Size
- Smaller Species: Generally have a shorter lifespan, often around 1-2 years.
- Larger Species: Can live longer, some reaching up to 3 years under optimal care.
Signs of Health Issues
- Size Anomalies: Stunted growth or unusually small size for age can indicate nutritional or environmental issues.
- Behavioral Changes: Lethargy or lack of appetite can be signs of health problems.
- Physical Signs: Abnormalities in the exoskeleton, such as discoloration or lesions, warrant closer examination.
Conclusion
In summary, the world of jumping spiders is as diverse as it is fascinating. Understanding their size chart is crucial for proper identification, care, and appreciation. From the tiny Euophrys omnisuperstes to the larger Phidippus regius, each species brings its unique charm and challenges. Whether you’re a seasoned arachnologist or a curious enthusiast, the study and care of these remarkable creatures can be immensely rewarding.
By respecting their natural behaviors, providing appropriate habitats, and observing them with care, we can continue to learn from and appreciate these extraordinary members of the arachnid family.

FAQs
Jumping spiders vary in size depending on the species. They can range from as small as 2 mm in species like Euophrys omnisuperstes to as large as 22 mm in species like Phidippus regius. The size chart in our guide provides detailed information on the sizes of various jumping spider species.
The size of the enclosure for a jumping spider should be proportional to its size. For smaller species, a modified plastic container with adequate ventilation may suffice. Larger species require more space, with terrariums or larger enclosures recommended. A good rule of thumb is to provide an enclosure that is at least three times the spider’s leg span in width and depth.
A healthy jumping spider’s abdomen should be plump but not excessively swollen. The abdomen size can indicate the spider’s health and nutritional status. It should be proportional to the rest of the body, with a slight bulge indicating a well-fed spider. However, an overly distended abdomen might suggest overfeeding or health issues.
Yes, jumping spiders can be kept as pets. They are known for their curious and interactive behavior, making them fascinating pets. However, it’s important to understand their specific care requirements, including habitat, diet, and handling, to ensure their well-being in captivity.
Jumping spiders are carnivorous and primarily feed on insects. Their diet includes fruit flies, crickets, mealworms, and other small insects. The size of the prey should be appropriate for the size of the spider, typically not exceeding the length of the spider’s body. It’s important to provide a varied diet to ensure proper nutrition.
