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
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|
|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
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
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
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:
- 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.

|Attribute||Jumping Spiders||Web-spinning Spiders|
|Hunting Technique||Active hunting||Passive hunting|
|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 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 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 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.
- Excellent vision
- Agile and fast movement
- Rarely bite humans
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.
|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
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.
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.

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!!!!
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.
Letter 2 – Male Common Hentz Jumper
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.
from coastal North Carolina
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.”

I’m not sure if I identified this spider correctly, but is it a Magnolia Green Jumper. I am an arachnaphobe normally, but this one intrigued me so I was able to take a couple of photos with my phone. I could swear it stopped to stare at me.
Your photo is quite blurry, but this may be a Magnolia Green Jumper, Lyssomanes viridis, which is pictured on BugGuide.

Geographic location of the bug: Pinellas, FL
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.

This little beauty is a Magnolia Green Jumper, Lyssomanes viridis, and she is actually a female. The Magnolia Green Jumper is a species with pronounced sexual dimorphism, meaning the male Magnolia Green Jumper looks like a very different species. Here is a BugGuide image of the male.

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.)
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 from Patagonia, Argentina

I´m sending pictures of this funny member of the Proscopidae family I found among dry sticks on coastal dunes near Las Grutas, Rio Negro, Patagonia.
It was a perfect stick and it would be impossible to find it without a small jump he did when I walk close to it.
Still trying to find its genus or species identification
Even I´m reading several bugs site as much as possible, your site is the only one I´ve been visiting every day for years!
Thanks for your amazing work. You are sharing the most unvisible beauty of the Nature
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 Encyclopedia.com, there are about 100 known species in the family and they are all endemic to South America.
Your photos are a wonderful addition to our website, and we eagerly await additional information either from you or our readership as to the genus and species of this fascinating creature.

Found this little green spider today and have no clue as to what it might be, I have compared it to so many different pictures but can’t seem to nail it. Have any clue? I keep running into some sort of jumping spider doing research. What was amazing is how the color of this little one really allowed me to follow the movement of his darker eyes and could tell he was watching me. A little cutie but what is it? Thanks!!
Your email did not indicate which Jumping Spider you kept “running into” while doing your research. Perhaps that is because this is a Jumping Spider in the family Salticidae, more specifically, the Magnolia Green Jumper, Lyssomanes viridis, a Southern species profiled on BugGuide.

Location: North Florida, about halfway between Jacksonville and Tallahassee, right on the Georgia border
May 16, 2014 6:37 pm
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?
This magnificent spider is a male Magnolia Green Jumper, Lyssomanes viridis, and you can compare your individual to this image on BugGuide. This close-up on BugGuide is quite impressive. The female Magnolia Green Jumper is a much bulkier spider with smaller mandibles.
Letter 14 – Magnolia Green Jumper
I found this guy by my house door yesterday. He is about the size of a dime and very fragile. Tried looking for a name and had a hard time finding one. I think he is a green lynx spider, but the images I have seen show them as pretty large. Any clue?
This is a Jumping Spider known as the Magnolia Green Jumper, Lyssomanes viridis. Your copyright information has all but obliterated the magnificent large jaws of this male specimen. The common name arises from this spider’s habit of waiting for prey while resting on broad green leaves like those of the magnolia.
Letter 15 – Non-Native Jumping Spider from Hawaii

Okay, so I did send this little woman in for identification, but I went further and started to look more on my own. This is a female Andanson’s House Jumping spider. It took me a while to find because it isn’t a native species, but rather has been imported from somewhere in Asia. (I am not sure where specifically.) I don’t really expect you all to post this, but I figured you might like the photograph of this little spider to be identified, and seeing as to how you don’t always have the time… (Kudos for all that you do identify, not really sure how you do everything that you do.) Thanks for your time, and of course I shall be continuing to follow this page for anything unidentified to try and help out where I can.

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?
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.
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.
