Jumping spiders are known for their incredible jumping ability and unique hunting tactics. These fascinating creatures differ from many other spiders’ species in several ways. Their most distinguishable feature is their excellent eyesight, which allows them to spot and track prey effectively even from a considerable distance UMN Extension.

While spiders are generally known for their elaborate webs, jumping spiders do not make webs to capture food. Instead, they use their exceptional eyesight and agility to stalk and pounce on their prey Wisconsin Horticulture. Their hunting style makes them beneficial as natural pest control agents as they help reduce the population of insects like flies and mosquitoes without creating bothersome cobwebs Menemerus bivittatus and Plexippus paykulli.

Jumping Spiders: An Overview

Family Salticidae

Jumping spiders belong to the family Salticidae, which is known for being the largest family of spiders, with over 6,000 species identified worldwide. These spiders are visually distinctive, exhibiting diverse colors and patterns.

  • Colors: Jumping spiders can display vibrant colors such as black, orange, or white.
  • Patterns: Some species have unique markings, like the Bold Jumper Spider’s irregular orange to white spots on its abdomen source.

Largest Family of Spiders

The Salticidae family dominates the spider world, comprising about 13% of all spider species. To put this into perspective:

Family Approximate Number of Species
Salticidae (jumping spiders) 6,000+
Other spider families 40,000+

This immense diversity enables jumping spiders to be found in various habitats, from gardens to forests.

Colorful and Active Hunters

Jumping spiders are renowned for their exceptional hunting abilities, aided by their large middle eyes, which provide them with excellent vision. These spiders are active hunters, relying on their sharp senses and movement rather than webs for capturing prey.

  • No webs for capturing prey: Jumping spiders do not spin webs to catch food.
  • Acute vision: Their large middle eyes enable them to see objects up to eight inches away.
  • Jumping ability: As their name suggests, they have remarkable jumping skills, allowing them to quickly pounce on unsuspecting prey.

Overall, jumping spiders are fascinating creatures that exhibit diverse colors, impressive hunting skills, and form the largest family of spiders. These agile arachnids are an essential part of ecosystems and provide unique insights into the world of spiders.

Anatomy and Vision

Eight Eyes and Color Vision

Jumping spiders have unique vision thanks to their eight eyes. With large middle eyes, they can see objects up to eight inches away. Their color vision is impressive, allowing them to perceive colors like humans.

Some key features:

  • Eight eyes play a crucial role in the hunting process
  • Exceptional color vision enables them to detect prey and mates

Abdomen and Spinnerets

The abdomen of jumping spiders houses the spinnerets, which create silk for various purposes. Spinnerets are small, tubular structures on the spider’s abdomen, and they are crucial for spinning silk.

Characteristics of the abdomen and spinnerets:

  • Abdomen is typically rounded
  • Houses spinnerets
  • Spinnerets produce silk

Silk Glands and Spigots

Jumping spiders have silk glands, which produce silk that is used to make safety lines, nests, and wrapping prey. Silk is released through tiny organs called spigots, located on the spinnerets. Although jumping spiders don’t build webs like other spiders, they still use silk in their day-to-day activities.

Silk glands and spigots features:

  • Produce silk for safety lines, nests, and prey wrapping
  • Spigots located on the spinnerets
  • Silk is not typically used for web-making
Feature Jumping Spider Web-producing Spider
Eye Count 8 eyes Varies
Color Vision Excellent Varies
Abdomen Houses spinnerets Houses spinnerets
Spinnerets Produce silk for safety lines, nests, and wrapping prey Produce silk for webs
Silk Glands & Spigots Present but not used for web-making Utilized for web-building

Jumping Spider Webs and Silk

Silk Production

Jumping spiders, like other spiders, produce silk from specialized glands. They use their silk for various purposes, such as:

  • Creating safety lines, also known as draglines
  • Constructing nests for resting, molting, and egg-laying

Types of Silk

Spider silk is impressive due to its:

  • Strength: It is stronger than steel of the same diameter
  • Elasticity: It can stretch several times its original length

Jumping spiders produce different types of silk, which serve different purposes. Examples include:

  • Dragline silk: Used for safety lines and anchor points
  • Cribellate silk: Some species use this silk, which has a wool-like texture, to build sticky webs

Web Architecture

While jumping spiders can produce silk, they typically do not make webs to catch prey like other spiders do. Instead, they rely on their excellent vision and agile movements to hunt down their prey.

In summary, jumping spiders utilize various types of silk for different purposes, but they typically do not construct webs to capture their prey. Their silk is notable for its strength and elasticity, and serves functions such as providing safety lines and creating nests.

Habitat and Behavior

Diverse Habitats

Jumping spiders can be found in a wide range of environments, from vegetation and wood piles to rocky areas and even your sock drawer1. They thrive in various habitats because they are highly adaptable and can easily adjust to different living conditions.

Predators and Prey

Jumping spiders are opportunistic predators, which means they consume a variety of prey based on availability1. Some examples of their prey include:

  • Insects
  • Other spiders
  • Small arthropods

In turn, jumping spiders have their own set of predators, such as birds, larger spiders, and reptiles.

Unique Hunting Techniques

Unlike many other spiders that rely on webs for capturing prey, jumping spiders utilize an active hunting approach1. They are known for their exceptional vision, which allows them to:

  • Observe potential prey
  • Measure distance and plan their jump accordingly

As part of their hunting technique, jumping spiders employ silk as an anchor line during ambushes1. However, they generally don’t spin elaborate webs as other spider species do.

Table: Comparison of Jumping Spiders and Web-spinning Spiders

Attribute Jumping Spiders Web-spinning Spiders
Hunting Technique Active hunting Passive hunting
Vision Well-developed Lesser developed
Web Usage Anchor line Trapping insects

Did you know? The Bagheera kiplingi is a unique species of jumping spider known for its vegetarian diet. It feeds mainly on Beltian bodies, which are nutrient-rich structures produced by certain species of Acacia trees2.

Notable Jumping Spider Species

Phidippus Audax

Phidippus audax is a common and conspicuous jumping spider often referred to as the “Orchard spider.” It has distinct markings: a black body with an irregular orange to white spot on its abdomen. This spider can be found in gardens and around homes, making it a familiar sight for many people.

Hyllus Giganteus

Hyllus giganteus is another species of jumping spider, though not as well-known as Phidippus audax. These spiders are larger compared to other jumping spiders and are known for their impressive size and bulging eyes.

Peacock Spiders

Peacock spiders are a group of species belonging to the genus Maratus within the jumping spider family. They are renowned for their bright colors and elaborate courtship displays. Male peacock spiders often exhibit colorful, patterned abdomens, which they display during courtship dances to attract females.

Feature Phidippus Audax Hyllus Giganteus Peacock Spiders
Habitat Gardens and homes Various habitats Various habitats
Size Medium Large Small to medium
Coloration Black with orange or white markings Varies Brightly colored and patterned abdomen in males
Courtship Not elaborate Not elaborate Elaborate courtship displays
Distinctive Trait Orchard spider Large size Colorful abdomen and dances
  • Some common features in jumping spiders:
    • Large, forward-facing anterior median eyes.
    • Do not build webs for prey capture.
    • Exceptional vision.
    • Quick and agile movements.

Interactions with Humans

Harmless but Fascinating

Jumping spiders are generally harmless to humans, as they rarely bite and are not considered dangerous. They are known for their excellent vision and remarkable agility, making them fascinating creatures to observe.

  • Features:
    • Excellent vision
    • Agile and fast movement
    • Rarely bite humans

Preventative Measures

To prevent jumping spiders from entering your home and becoming a nuisance, you can take the following steps:

  • Seal cracks and gaps around doors, windows, and other openings.
  • Sweep away or relocate webs and spiders found near your home.
  • Keep your living space clean and free of clutter that would provide hiding spaces for spiders.

Pros of preventative measures:

  • Reduce the number of spiders in your living space.
  • Minimize the risk of encountering a jumping spider while indoors.

Cons of preventative measures:

  • May require time and effort to maintain a spider-free environment.
  • Potentially lose out on the benefits of having spiders, such as natural pest control.
Method Pros Cons
Sealing openings Discourage spiders from entering your home May be time-consuming and labor-intensive
Sweeping webs Quickly eliminate current spider residents May evoke fears for those with arachnophobia
Maintaining clean living space Reduce hiding spots for spiders Requires consistent upkeep and cleaning

Reproduction and Spiderlings

Mating Dance

Jumping spiders, specifically Phidippus regius, exhibit a fascinating mating dance to attract their potential partners. Males use their brightly colored bodies and elaborate movements to impress females.

Offspring Development

After a successful mating ritual, female jumping spiders lay eggs in a protective silken sac. Soon, the eggs develop into tiny spiderlings that resemble miniature versions of adult spiders. Some noteworthy features of spiderlings include:

  • Eight legs
  • Eight eyes
  • Small size
  • Similar appearance to adults

Here is a brief comparison of jumping spider spiderlings and adult jumping spiders:

Features Spiderlings Adult Jumping Spiders
Size Tiny Larger than spiderlings
Color Duller Bright and vivid
Maturity Need to grow and molt several times Fully developed

As spiderlings grow, they molt multiple times, eventually reaching their adult size and gaining their vibrant colors. The jumping spider’s life cycle from mating dance to spiderling development is an intriguing aspect of these visually-adept arthropods.

Over the years, our website, has received hundreds of letters and some interesting images asking us about these insects. Scroll down to have a look at some of them.

Letter 1 – Mermithid Worm parasitizes spider


spider with HUGE “parasite” (worm)
Hi. I sent an email several weeks ago (4-8 weeks) re: a spider with parasite. At the time, I was having problems with my internet service….so, I want to resend the email just in case you never received the original. Thanks for your advice/information about “my parasite problem”. July 2007-I saw what I thought was a fire ant in my basement living area (we do have problems with fire ants) because its abdomen was so large. I tried to catch the ant, but it was too fast. It jumped out of my bug catcher as quickly as I got it in. To say the least, he died. It scared me to death when he jumped out…..I thought he was going to sting me. I reacted……but anyways…….As I was doing research (to see if this large red ant was a fire ant), I noticed its intestines MOVED! After a couple of minutes, I realized that this was not the ant’s intestines…….it was a “worm” (parasite)!!! Sorry-no pictures that day! 2 weeks later, I was sitting in the floor in my living area of my basement. Low and behold, I seen a “worm” stuck to the bottom of my entertainment center with a dead ant next to it (I included pictures). I could see where the parasite had “busted” out of the ant’s abdomen. The “worm” was dead (dried up-guess it didn’t find a host in time).Attached is 2 pictures The last straw…….about 2 months ago, a huge Wolf spider ran towards my living area in my basement. I sprayed it with bug spray, and almost immediately, I saw a big “worm” bust out of the spider’s abdomen and begin to wriggle around looking for a host. I took many pictures and even a video (will try to send if I can figure out how to make smaller). 4 pictures are attached My concern is this……are we being attacked by parasites? I have 2 small children (ages 2 & 5) that both suck their thumbs. Do we have a parasite problem that needs to be dealt with? Is this common to see these parasites? Are they any harm to humans? Thanks so much for your help!!!!

Hi Monica,
We found a website entitled The Worm, the Spider and the Coffee Cup that discusses the Mermithid Worm as an internal parasite of spiders. Here is a quote from the site: “Mermithid worms are internal parasites whose infective larvae enter spiders directly or via ingested food. Once inside the spider, the tiny worm obtains nourishment from it’s hosts body fluids, digestive glands, gonads (‘parasitic castration’) and muscles. As a consequence the spider becomes progressively more debilitated, but doesn’t actually die. This is because the spider’s vital organs usually remain intact, even though all of the abdomen, and occasionally part of the cephalothorax, may be filled with worm coils. Eventually in a scene reminiscent of the movie “Alien”, the gorged worm bursts out of the body of the debilitated spider, which finally dies after this macabre event. Before it dies, however the spider often has to perform one more task for it’s deadly parasite. In some mermithids, the final free-living stage of the worm is aquatic, so that it is advantageous for the worm if its emergence can take place near a water body – a pond, a creek or puddle. To increase this likelihood, such worms seem able to induce their hapless hosts to seek water, spiders sometimes actually walking into the water before the worm emerges. This behavior may result from thirst-induced activity as the worm consumes the spider’s body fluids. Whatever the reason, there is no doubt that the spider’s water seeking behavior helps to ensure the parasite’s survival and propagation.” We also located a technical paper online. Nothing indicates the parasites are interested in your children.

Spider? with long front legs
May 27, 2011
Dear what’s that bug?,
First of all I want to thank you for being such a knowledgable resource. You have helped me several times with some bizarre looking insects. Here is my resent encounter with what seems to look like some type of spider? I was sitting under a tree and all of a sudden this critter showed up on my canvas. I tried to get him off with trying to coax him on to a piece of paper. To my shock he must have springs in those legs. He was just hopping. It was quite humorous, because he would looking right at me while I was trying to catch him. I will admit he was creepy with the legs in the front being longer. I also noticed that he seems to stand tall with threatened and isn’t afraid to lunge at you. Every time he looked up his bottom would seem to turn sideways. He did jump producing a string, I’m not sure if all arachnids do.
Thanks again!

Common Hentz Jumper

Hi Jennifer,
This is certainly a Jumping Spider in the family Salticidae, though we have our doubts that we have properly identified the species.  Your individual greatly resembles images of
Bagheera prosper that are posted to BugGuide, however, BugGuide indicates its range as being “Texas and south into Mexico.”

Time: 03:48 PM EDT
Your letter to the bugman:  Hello! I found this charming lime green spider a few days ago, at school on a handrail underneath an oak tree. At the time I found him, it was a early summer day, very hot. After a little bit of spider-chasing, I had him on my hand. He didn’t seem that scared, and was quite interested in my phone, which he attempted(and succeeded), on multiple occasions, to jump onto. I’m writing this right when I have access to the internet again!
This charismatic little spider was about as big as the nail on my thumb, and moved in quick bursts. It was fond of jumping, which was odd because the only thing that resembled that of the jumping spiders i’m familiar with is the face. I considered keeping him for a little while just to look at him and study his feeding behaviour, but I thought that would constitute as arthropod kidnap and I thought he’d like his tree a lot better. I let him go back on the trunk of the oak tree(which was a bit hard, since he was very interested in my upper arm), so he wouldn’t be squashed by passerby.

Letter 5 – Red Jumping Spider


Who is this spider?
I found at least half a dozen of these spiders tucked under the rims and between the sections of some plant 6-packs in which I’ve got seeds planted. The packs are in flats resting on the ground in the garden. This spider is about an inch long; some of the others looked smaller. The web is very white. I’m in Glendale (Los Angeles) California. From general body shape and hairiness I suspect a jumping spider, but couldn’t find any pictures of one with this lovely orange color. (Your fall 2005 web page was down when I went looking for a picture.)

Hi Sallie,
This is one of the Red Jumping Spiders in the genus Phidippus, probably Phidippus formosus. These are hunting spiders who do not build webs to trap prey, but adult females, according to Hogue, “construct a funnel-like web that is usually in contact with the soil; this structure is used as a retreat for the adults and a safe repository for the eggs.”

Jumping Stick

Happy New Year Mirta,
It is nice to hear from you again, and also to hear how much you appreciate our website.  This is an entirely new family for us, and we needed to do a bit of research to verify that it should be categorized with the grasshoppers on our website.  Like common grasshoppers, this Jumping Stick is in the Order Orthoptera, and the Grasshopper suborder Caelifera, but then the divergence happens.  The family Proscopiidae is new to us.  We crosschecked the taxonomy on Wikimedia with BugGuide to come to that conclusion.  The infraorder Acrididea includes the other grasshoppers,  but the superfamily Eumastacoidea does not seem to be represented with North American species, though BugGuide does have a mention of a fossilized member of Proscopiidae that was found in Brazil.  According to, there are about 100 known species in the family and they are all endemic to South America.

Found this little guy on a camping trip last weekend. He runs around pretty quick on the ground, and jumps a pretty good distance. He was super tiny; the white thing he’s standing on is a plastic cooler, and the little dark specks around him are grains of dirt. I don’t think he builds webs. We kept an eye on his location and kept checking up on him every few hours; he didn’t move from the top of this cooler until after more than a day. From what I’ve read, it sounds like some sort of crab spider, but I haven’t found one with such a slender thorax and such large, strange-looking mouthparts. Any idea?

Phidippus regius.  The Regal Jumper has several common and some uncommon variations, and your specimen is a very close match to this image posted to BugGuide from Florida.  Jumping Spiders are considered harmless to humans.  They have excellent eyesight and they stalk their prey as opposed to snaring prey with a web.

Letter 22 – Red and Black Spider from Papua Indonesia


Glossy Red and black spider from Papua highlands
Location:  Tembagapura, Papua, Indonesia
October 2, 2010 10:08 pm
We see these small spiders with a red cephalothorax and upper half of legs and glossy black abdomen and lower half of legs around the house here in the highlands (2500 meters) in Papua, Indonesia. Any ideas what they are?

Red and Black Spider from Indonesia

Dear Kevin,
This is one awesome looking spider.  We want to GUESS that this might be a Cobweb Spider in the family Theridiidae, the same family that includes such black and red poisonous spiders as the Black Widow from North America and the Red Back Spider from Australia.  Red and Black are codified warning colors in the insect and bug* worlds, and that warning is generally poison.  We hope our readership will come to our rescue with the name of this begloved she-beauty.

* Ed. Note: Bugs are loosely defined as “Thing That Crawl” in Daniel’s new book The Curious World of Bugs.

Spider from Papua

Hi Daniel,
Thanks – I think you steered me in the right direction.  I’m going to guess this is in the Nicodamidae family which was split out of the family Theridiidae (according to what I can find on some Aussie web sites) about 15 years ago.  The Australian Red and Black spider (not to be confused with the Red Back) looks almost identical to mine and is a member of this family.
This one has a body length of 8mm, and from what I can tell looking at pictures would appear to be a female.

Thanks for writing back Kevin.  As you did not provide a link, we searched and found the family Nicodamidae on the Spiders of Australia website and there were photos of Nicodamus peregrinus, which looks very close to your specimen.  The webpage indicates Nicodamus peregrinus can be found in Eastern Australia, and that “The family Nicodamidae consist of nine genera with 29 descibed species, all living in Australia, one in New Guinea and one in New-Zealand.”  The Esperance Fauna website also devotes nice coverage to the family Nicodamidae.

Sorry for not including the links – yes, those were the sites I found most helpful also.

  • I completely forgot to mention that I did have the Bishop Museum Scientists, here in Hawaii, verify my identification. They themselves have a nifty little website dedicated to identifying the species of Hawaii. Here is a link to the posting as well. Also thanks for the tip on the correct way to type the scientific name. I hope the knee surgery went well, and heals properly.

  • Hey I found this too here in Surrey BC… I found it as “Johnson Jumper,” but I think that is just an alternate name for “Red Jumping Spider.” My photo is here:

  • This species has been known to Hawai’i, Kaua’i and O’ahu since 1876. I don’t see what you’re so excited about. These spiders are everywhere here yea

    • Goodness gracious, what a killjoy. Since we run a global website, we are always thrilled to get new species to our website, even if they are common at the site of the sighting. We will not apologize for our enthusiasm. As the curator of an insect museum, we would think you would appreciate the fascination the public has for bugs, even common species.

  • looks like a new spider bite lol

  • How pretty!

  • seen him the other day in northern manitoba

    i have a spider similar,or same not sure about fussy but very black and very red. super fast. there are three in very close together that I have seen all out at once.
    but I would say it is at least 1/3 inch to 1/2 inch which i think is large for the island..

    .is it toxic, the bit to me?

    or harmless to humans if i get bitten? I am allergic to and skin near a bit gets infected by such as mosquitos and wasps ..bea do not sting me I can hold and play with them..

    • We cannot speak about individual sensitivities. That is the job of a doctor. A bite from a Jumping Spider would not be a serious danger to the average person.


    • As the posting indicates, we believe this is Phidippus formusus. Jumping Spiders have venom, but they are not considered dangerous to humans.

  • many years ago, I became very ill with a lot of symptoms. I will not go into this, and do not blame this worm in any way, but several parasites were identified that came from my stool and one was a mermithid worm.

  • Each Autumn when I begin to find crickets jumping into my pool. I also find at least 20 to 30 white “worms” about 10″ to 14″ long and as thin as uncooked “angel hair” pasta.
    These are free swimming white worms found in the water of an in-ground “salt system” pool on my farm. In the robot cleaner and strainer baskets I have found crickets with these worms emerging from their abdomens.
    The worms die within a day or two in the mild chlorine and slightly salt water of the pool, but removed to a jar of fresh water they can live for almost two weeks.
    They look like animal round worms, but all our livestock are tested by stool sample twice a year and no parasitic worms. are found.
    Are these NEMATHIDS?

  • So I found one of these on my trash can outside today. Kinda freaked me out but one website I found said its not poisonous. I’ve also looked at photos and it seems to be a female. Is there a safe and humane method you suggest to keep this spider (and other spiders) from laying its eggs in my trash can or possibly on a plant nearby? I really don’t want to exterminate but I was hoping another method may work instead.

  • I have these inside my foot. My apartment is infested with these. It all started with an ant problem. These do not show up in the stool test since they are large.

  • I find one in texas

    This is in the Marpissa genus. It looks like a female Marpissa pikei (Pike slender jumper.)

  • Thanks bug man just found this in my bathroom and I was relieved to find that is was not dangerous

  • This is not a long jawed orb weaver. It is likely a male, magnolia green jumping spider, Lyssomanes viridis.

    I found one exactly like this on Vanderbilt campus today! It was also on a (black metal) rail, and as my phone approach her, she seemed to be keen on jumping. Then I got to my office and looked it up and found this page. Thank you for letting me know what it was! I have a photo, but I don’t see how to attach it. Cheers.
