Jumping spiders are fascinating creatures known for their incredible ability to leap significant distances relative to their size. They belong to the Salticidae family, which is home to over 6,000 described species, showcasing a wide range of diversity in size and appearance.
These lively arachnids vary in size, typically ranging from 1/10 to 1/4 inches in length. For example, the daring or bold jumping spider, commonly found in South Carolina, features three white to red dots on its abdomen and falls within this size range. Another familiar species is the zebra jumping spider, often found indoors, sporting white stripes against a blackish-brown background.
Jumping spiders show impressive visual capabilities, making them successful predators in their respective habitats. A study conducted at Harvard involving the Menemerus semilimbatus species demonstrated that these tiny spiders can even identify biological motion cues, hinting at their complex visual system.
Jumping Spider Overview
Characteristics of Jumping Spiders
Jumping spiders belong to the largest family of spiders, Salticidae, which hosts over 6000 described species as of 2019, and are distinguishable by their small-to-medium body size covered with a dense layer of iridescent scales or hairs1. Key features include:
- Excellent vision with four pairs of eyes
- Incredible jumping ability, covering up to 50 times their body length
- Stout and compact bodies, typically 1/10 – 1/4 inches long2

Taxonomy and Species Diversity
Jumping spiders are classified as true spiders belonging to the phylum Arthropoda, class Arachnida, and order Araneae4. Their vast species diversity is exemplified by the following examples:
- Phidippus audax, known as the bold or daring jumping spider, frequently found in gardens and around homes3
- Habronattus pyrrithrix, displaying striking contrasts in coloration1
- Zebra jumping spider, commonly found indoors, characterized by white stripes on a blackish-brown background2
| Common Name | Species | Habitat | Appearance |
|---|---|---|---|
| Bold jumping spider | Phidippus audax | Gardens, homes | Black with irregular orange to white spot |
| Habronattus pyrrithrix | Habronattus pyrrithrix | Various | Striking contrasting colors |
| Zebra jumping spider | Salticus scenicus | Indoors | White stripes on blackish-brown background |
Jumping spiders not only showcase an impressive array of sizes, colors, and patterns, but also exhibit remarkable abilities to jump impressive distances and possess exceptional vision. They are a fascinating and diverse group within the Arachnida class.
Physical Appearance and Anatomy
Body Length and Size
Jumping spiders are small creatures, with body lengths ranging from 1/10 to 1/4 inches. The largest jumping spider in eastern North America, Phidippus regius, is aptly named due to its size1. Some examples of common jumping spiders are:
- Daring or bold jumping spider: three white to red dots on the abdomen3
- Zebra jumping spider: white stripes with a blackish-brown background3
Colors and Patterns
Jumping spiders exhibit a variety of colors and patterns, including:
- Black with distinct irregular orange to white spots5
- Iridescent green or blue on their cephalothorax4
- Stripes, spots, and other intricate patterns4
These colors and patterns aid in camouflage and attracting mates.
Eyes and Vision
Jumping spiders are known for their exceptional vision, thanks to their four pairs of eyes2:
- Two large, forward-facing principal eyes
- Two smaller, forward-facing secondary eyes
- Two lateral pairs of eyes for peripheral vision
Their vision is essential for hunting prey and navigating complex environments.
Habitat and Distribution
Geographical Range
Jumping spiders are found all around the world. Some notable locations include:
- Australia
- Tropical forests
- Deserts
- Temperate forests
- Scrubland
Their adaptability allows them to thrive in various environments, from tropical forests and deserts to temperate forests and scrubland. One exceptional jumping spider, Euophrys omnisuperstes, even inhabits Mount Everest, at extremely high altitudes.
Types of Habitats
Jumping spiders are known for their ability to adapt to diverse habitats, examples as follows:
- Forests: These spiders often inhabit leaves, tree trunks, and branches in both tropical and temperate forests.
- Urban environments: They can also be found in houses, gardens, and other man-made structures.
- Deserts: Despite harsh conditions, some jumping spiders have adapted to thriving desert life.
Jumping spiders are quite versatile, making them a fascinating subject when examining their habitat and distribution. Their quick jumps enable them to navigate various environments, making them a successful species in different parts of the world.
Behavior and Hunting
Prey and Diet
Jumping spiders are carnivorous predators with a diverse diet consisting primarily of insects, but they are also known to occasionally consume other spiders. Some examples of prey they might hunt include:
- Flies
- Grasshoppers
- Crickets
- Moths
Hunting Techniques
Jumping spiders use their exceptional eyesight and stealthy movements to actively hunt their prey during the day. These hunters have eight eyes, which provide unparalleled vision, crucial for detecting and stalking their targets.
Jumping Ability
A notable feature of jumping spiders is their ability to leap impressive distances, which is useful in both hunting and evading predators. Here are some key characteristics of their jumping ability:
- They can jump up to 50 times their body length
- Their muscles and hydraulic systems propel them to great heights
Jumping spiders rely on their remarkable agility and do not produce venom to subdue their prey.
| Feature | Jumping Spider | Other Spiders |
|---|---|---|
| Hunting strategy | Active hunters | Mostly passive, using webs |
| Eyesight | Excellent, with eight eyes | Varies, generally not as sharp |
| Jumping ability | Can jump up to 50 times body length | Limited or none |
In summary, jumping spiders are skilled hunters known for their diverse diet, remarkable eyesight, and impressive jumping abilities. Their unique set of characteristics sets them apart from many other spider species.
Life Cycle and Reproduction
Courtship and Mating
Jumping spiders exhibit unique behaviors during courtship and mating. Males usually perform elaborate dances to attract females. These performances may include displaying bright colors, waving their legs, and vibrating their bodies. If successful, the male and female will mate.
Egg Laying and Development
After mating, female jumping spiders lay their eggs inside a carefully constructed silk sac. The number of eggs can vary greatly depending on the species. The eggs go through several developmental stages before emerging as spiderlings. As they grow, spiderlings will molt multiple times, shedding their exoskeletons to accommodate their increasing size.
Here are some important characteristics of jumping spiders’ life cycle and reproduction:
- Adult size: 1 mm to 23 mm (most between 5 mm to 10 mm)
- Male size: 8 to 9 mm (in some species)
- Female size: 8 to 10 mm (in some species)
- Reproduction period: fall to spring
Comparison of male and female jumping spiders:
| Feature | Male | Female |
|---|---|---|
| Size | 8 to 9 mm (in some species) | 8 to 10 mm (in some species) |
| Coloration | Sometimes brighter | Less vibrant |
| Role in courtship | Performs dances to attract | Observes male’s performance |
Pros and cons of jumping spiders’ reproductive habits:
Pros
- Elaborate courtship ensures successful mating
- Silk sac provides protection for eggs
Cons
- Male spiders must perform well to be accepted by females
- Silk sacs can be susceptible to predation if not well-hidden

Letter 1 – Unusual Jumping Spider from the Philippines
Subject: Mystery bug in the Philippines
Location: Philippines
June 19, 2014 7:08 am
Hi Guys,
Spotted this bug here in the Philippines and was wondering if you might now what it is? Seems golden in body colour. Many thanks!
Signature: Frank
Dear Frank,
We wish your image had more detail. This appears to be a Spider, and our best guess is a Jumping Spider in the family Salticidae, however that is quite an unusual appendage at the end of the body. We have not had any luck finding anything that matches this spider in appearance, but we will continue looking around on the web.
Hi Daniel and Frank:
You are right, Daniel, it is a Jumping Spider. It looks like a species of Mantisatta (Salticidae: Ballinae), a small genus with only two species. Mantisatta trucidans lives only on the island of Borneo and M. longicauda is endemic to the Philippines. According to Wikipedia “The genus name is combined from mantis (because of the long first legs) and the common salticid ending –attus”. The front legs in Frank’s photo don’t appear especially long but it looks like they may be folded under or perhaps around something. In all other respects it looks very similar to M. longicauda. The species name (longicauda) clearly refers to the unusually long and tail-like abdomen. Regards. Karl
Letter 2 – Regal Jumping Spider in Tent
What’s she doing in there?
Wed, Oct 29, 2008 at 7:47 AM
I happened accross this little spider hiding this morning. I am in north central Florida (Branford) and we had our first freeze overnight. I was taking some photos this morning and found what looked like a cocoon but there was a spider hanging out of it. My curiosity has been working at me and I had to go back and coerce the spider out to learn a little more. I got it to come out and identified it as a female regal jumping spider. I have read that they do make tents but I can’t find any photos of their structure. Is this her tent or did she commandeer some poor cocoon to get out of the cold this morning?
Amy
Branford, FL
Hi Amy,
We needed to research this tent making with regards to the female Regal Jumping Spider, Phidippus regius. We found images on BugGuide that showed a female in a tent in Orange County Florida. This tent is just a shelter for protection and probably helped your spider excape the frost. This is a highly variable species, and BugGuide shown numerous photos of the color variations. You should be commended on your identification.
Thanks so much for your response, I have admired your site for quite some time and I am pleased to be a part of it now. Aside from your site, I also get spider info from the book Florida’s Fabulous Spiders. That is where I found the ID for this spider. The Florida’s Fabulous Series is no substitute for good old field guides, but they are great for learning interesting facts about some common species. Thanks again for the info,
Amy
Letter 3 – Simon Asks: Do Mating Blues mimic Jumping Spiders?

- Mating Common Bush Blues look like Jumping Spider
Daniel,
What caught my eye with these Cacyreus lingeus is that I also saw a pair mating, and after a bit of maneuvering and jostling about, they settled down into the one position for about 5 to 10 minutes or so, and the pattern of the “eyes” on the wings of the joined butterflies, as well as the final configuration of both showed a distinct mimicry of a jumping spider.
In the brief research that I have done, I have not seen anything written anywhere of two separate insects actually using mimicry as a defense mechanism before, although they were still for quite a while so were fair game without some defense system.
Have attached the photo to see what you think?
That is an awesome and astute observation Simon. They really do look like the face of a Jumping Spider. Perhaps it is time for you to write a paper. We will be adding this photo to your original submission as well as making it a unique posting that is a feature.

A long time reader, Curious Girl, just forwarded us this link to the Days On The Claise blog with a very similar theory.
Letter 4 – Spider Romance!! Courting Jumping Spiders, Phidippus species
two unidentified spiders
Dear Bugman!
I have here two photos of different spiders. The male with the orange abdomen has eluded ID for too long! I happened to catch him while loving on his woman. He presented her with a grasshopper, and while she munched happily on her tasty treat, he got around to more importnat things. I managed to take a nice succession of photos, but this one had the best representations of both of them. I don’t need to tell you how awesome it was to witness this event. The second photo is a small spider with moderately long front legs, the first two pair I believe, found on the wall. He folded his legs up tight in response to my camera in his face, so I couldn’t get him to pose. I took these pictures West Texas this month.
Thanks!
Wendy A.
How romantic is that Wendy?
We love your courting Jumping Spider photos and the story as well. Your Jumping spiders are from the Family Salticidae, probably the genus Phidippus, and possibly Phidippus formosus. Hogue writes: “The brilliant red abdomen of this species frequently attracts attention in the spring, when it is most active. … The Red Jumping Spider is not considered dangerous, although its bite may be painful to sensitive persons. Like all jumping spiders, it has a pair of very large eyes. This is a hunting spider and thus does not use a permanent web for trapping prey. … Both sexes spend the daylight hours wandering over the ground and vegetation in search of small invertebrates, upon which they may leap from some distance.” Your spider might also be Phidippus insolens, which exhibits dimorphism in both sexes, meaning that the males and females are differently colored as well as having different color variations within the sex. One form has a black cephalothorax and red abdomen like your photo. Your second photo might be a Domestic Spider, Theridion tepidariorum.

Good Morning Amber,
You are correct that this is a Jumping Spider in the family Salticidae, but despite its distinctive markings, we have been unable to identify the species after scanning through all the genera on BugGuide. Perhaps one of our readers will have better luck than we have had with a species identification. Interestingly, as we were linking to BugGuide, we stumbled upon this image of the Bronze Jumper, Eris militaris, on BugGuide that looks closer than any other image we found.Â

Hi Bugman!
… The final one is of a jumping spider. Not technically bugs (or even insects!), but I thought I might send it in. All pictures were taken the same place as the skipper, along a rocky beach. …

Hi again Geoff,
We believe your Jumping Spider is a Zebra Jumper, Salticus scenicus, based on photos posted to BugGuide. We believe this is another new species for our website, and though we greatly appreciate the photo, we have an additional request. Our readership tends to desire information as much as they like to see nice photos. Since it is now probably very cold in Canada, we suspect your photos were taken earlier in the year or perhaps in some previous year. It would be very helpful to have that information. Also, it would be nice to get any information on behavior or unusual conditions that accompanied the sighting.
Letter 11 – Zebra Jumping Spider
Zebra Spider?
Location: Chicago, IL
April 16, 2012 2:03 am
Just wanted to share this picture of what I believe is a Zebra Jumping Spider, after doing some searching on the internet.
We’ve been finding a bunch in our house! They are very pretty.
Signature: Cheyenne
Dear Cheyenne,
We agree with your identification of the Zebra Jumping Spider, Salticus scenicus. According to BugGuide it: “Seems to be an imported European species that is now widespread in North America.” Jumping Spiders are hunters that do not build webs. They have excellent eyesight.
This is an adult female Phidippus clarus, not P. regius.
Looks like a young Epeus spider.
That is a brilliant idea! The lines along the wings can read as legs, and the little sticky-off bits at the back of wings could look like pedipalps… Seriously, write a paper! Do more research! This could be a pretty significant scientific discovery!
We believe Simon is on to something.
Sorry to burst your bubble here – but why would they mimic such a small predator as a Salticid spider? The purpose of the false heads on lycaenid hind wings seems to be to trick birds into pecking the wrong end of the butterfly. Any such bird would probably relish a Salticid spider even more than a butterfly – more meat!
Dear Steve,
Our bubble is not burst. We understand the accepted explanation of the oculi and filaments on the hindwings of Gossamer Winged Butterflies, but even the most jaded reader can’t deny the resemblance between the mating Blues and the Jumping Spider, even if it is purely coincidental.
Steve,
Thanks for the input and there is definitely no chance of bursting my bubble, as no bubble exists at the moment.
This was just purely an observation that I made when I saw these butterflies recently. The configuration of the pair whilst mating immediately gained my attention. Initially they were dancing round the flower, and it was two to three minutes before they actually settled into this pattern and remained stationary in this position for well over 10 minutes, enough time for me to head to the house a hundred meters away and change the lens to a macro. Which I why I thought I would post here, as to see what others with more knowledge and experience thought of this particular case.
The allusion to a jumping spider was only apparent from a horizontal viewpoint and when the butterflies were in a vertical stance and now on reflection I can’t help but wonder if this was not also a reflex reaction to my presence, as the jumping spider configuration was definitely directed at where I was kneeling. Not only the oculi and filaments gave this impression but the irregular pattern on the underside of the wings as well as coloration also immediately drew similarities to some of the few jumping spiders I have seen here.
In trying to name this species I did do some research over the last few days and did note that it is accepted that the oculi and filaments on the extremities of the wings are to confuse predatory birds and thus in losing only a small portion of the extremity of the wing can escape relatively unharmed.
Although after taking this photo, I did have a couple of thoughts on that. Firstly if this mimicry was to protect against birds only, then it actually would fail because most birds would be observing from above the horizontal plane and at acute or obtuse angle, hardly any predatory birds would be on the plane where this mimicry would have greatest affect. Although I have noticed that the Brown-headed Tchagra seems to be the most dangerous for flying insects here and these do hunt on the ground and from low bushes and tree branches, but as you have mentioned I don’t know if this posture would deter the Tchagra from a quick butterfly snack.
I also noted in some of the reading I have done over the last few days of other butterflies mimicking jumping spiders, in particular metalmark moths of the Brenthia genus mimicking jumping spiders, which is one of their predators, and jumping spiders responding to Brenthia with territorial displays, indicating that Brenthia were sometimes mistaken for jumping spiders, and not recognized as prey. These were individuals though whereas in this case it was apparently a pair of Cacyreus lingeus coordinating the deception.
I have seen other butterflies taken by spiders, as per the photo here, which triggered the thought process that this configuration was aimed at deterring predatory jumping spiders whilst the mating Cacyreus lingeus were at their most vulnerable, and being stationary for over ten minutes would seem to be that case, hence the observation that this could be a deterrent against jumping spiders rather than birds.
Simon
Very nice Simon. We are ready for that paper from you. It is truly in the spirit of early naturalists who learned so much from patient observation.
Steve,
I thought of that too. The thing is, there’s really not much that a tiny butterfly could do to keep a comparatively large predator like a bird away. However, even if a bird did attack what it thought was a jumping spider, it would still end up with a mouthful of wings, meaning the mimicry would have served the purpose you stated. Additionally, this mimicry could be effective against smaller predators, such as spiders.
Your site has displayed a related post which also appears to have spider eyes, “Mating Reakirt’s Blues”:
http://www.whatsthatbug.com/2012/11/03/mating-reakirts-blues/
This eyespot pattern is visible on many Blues and Hairstreaks. The mating position is similar, so this visual similarity to the eyes of a Jumping Spider will be evident in many mating Gossamer Winged Butterflies.
Interesting.

How very cool!! I’d been reading posts from a knitting page, so was pleasantly surprised to find this a spider and not a sweater!!
Curiosity drove me to bring this ‘unusual jumping spider’ [same photo] to my own collection. I’ve added front legs a time or three. I have chopped off the elongated ‘tail.’ If it was originally the ‘Mantisatta longicauda’ – The photo is doctored/shopped, and was before you or I ever saw it. – I dare anyone to find another photo anything like this one, with a tail like that. [The tail seems to be a LEG fron a different spider? – No credentials here, but I am suspicious.
I don’t think it has to be identical, the link looks like a match to me.
I threw it out . Looks fake to me. Combination? Maybe. Photo must be OLD.
This appears to be Tutelina similis or Tutelina elegans. The juveniles are apparently indistinguishable between the two subspecies and I’m not an expert, but I would say it is a female Thick Spined Jumping Spider, Tutelina similis.
