I was hiking and saw this spider in the mouth of a cave in the Ozarks in Arkansas (USA). I believe it is some kind of wolf spider. I have never seen a spider in the wild this large, except for tarantulas in Texas (USA). The approximate size from the tip of back leg to front was 7-8 inches. It was bigger then my hand and I am 6'1" tall man. The spider did not have anything to reference size and did not want get too close, though I am sure it was harmless. I can go back to cave and take same picture holding a ruler to the rock if needed.

I believe my initial guess was off mark. I am thinking this may be a fishing spider. I only say this due to it being on a vertical surface and having banded/striped legs. I have never heard of one attaining this size before. Any info on this spider is greatly appreciated.

looks most like a Meta ovalis with a span of about 10 CM.

Can anyone identify this spider?

Woo! My money is on it being a common desert tarantula - Aphonopelma Chalcodes or Iodius. But I think there are about 50 different species of tarantula in northern Nevada, so I can't be certain (Not an expert, I just think tarantulas are neat).

Since it's early fall, tarantulas are especially active for mating and migration. Because of the dark color this one might be a male - especially the black on the legs. They can live about 5 years and females up to 20!

Growing up in Reno I've seen these things most in the Virginia foothills around this time of year. They eat crickets and aren't a bother. They might rear up if you get too close. I'm not sure if these species flick their hair defensively, which can get in your eyes or skin and be irritating. I wouldn't want to find out what their bite is like either - though I've heard it's not serious - more like a real bad bee sting than something dangerous like a black widow bite.

When I was in high school, my buddy and I captured one and took it to our biology teacher who told us all about them (we later let it safely go in the hills where we found it).

Interestingly, tarantulas have book lungs - little stacked gill-like formations on their abdomen for breathing - and if they dunk in too much water it's no good.

I'm scared of spiders, but getting to know tarantulas has been really fun and helped me face my fear.

That is called the "Run-and-scream-like-a-little-girl" spider.

But, if we find Sac Spiders or Violins, bye bye. The Widows tend to stay outside and we hardly see them. Unfortunately, if one should be found inside and I am not here she will meet a newspaper from the wife. As for Sacs and Violins i do not let them roam our homes cause they are aggressive and won't think twice to bite. The violin ain't as aggressive as the Sac, but extremely poisonous. In S.Africa we have learned the big ones are harmful, though they can pack a punch, it is the smaller ones we stress about.

The Rain Spider is extremely placid and would sit for hours in one spot. Everyone still jumps when they see this large spider, but they are seriously cool spiders. They come, visit for a few hours and then they leave. And I know if a violin crosses its path, it will do the killing for me.

Let me examine it with a flame thrower and I can give you a better estimate.

No effing way that critter and me are in the same house together. Sorry my arachnoidial friend but one of us has to go. and it ain't me.

That thing looks like its big enough to latch on to your face like the movie Alien.

I hate spiders too. Why did we look?

Yeah, it reminds me of a garden spider too.
Look for the zig-zig pattern on the web. Which is a warning for birds not to fly through it.

Like Char-lee said, there are quite a number of body and leg patterns.
Some of them will do push-ups on their web to make sure you know they are in-da-house, and to leave them alone.
One of my favorite spiders!

I didn't see anything that could show the size of your spider. One thing i always do is look up spiders for my area really helps to find the type.

. gotta go shower and scrub off the crawly-skin feeling with a steel wool pad now.

The spider, according to my friends, were about 80mm (3 inches) with legspan.

Here's the one that's a frequent visitor at my place. I would never kill it. truly a placid spider, and cause it goes against my belief in killing spiders. But, my belief stops at Sacs and Violins

Another one taken at my friend's place

Now these big ones are not dangerous at all. They leave you alone. I have had a few "arguments" with arachnid lovers who gets angry when i say i do kill Sac Spiders and Violin (Recluse) spiders.

I have not come across a Sac who would let me pick it up without going in defense and attack mode. And they are super quick. The Violin i would not even try to pick up, because they are simply bad news.

I could put my hand right next to a Huntsman and they won't move.

Your friend seems to have a very spider happy place!

After a face to face run-in with a hobo ( ) , I must admit I feel a certain sphincter pucker when I see a picture like that (beautiful as it is).

Eep, time to go scour every corner of the house and make sure I dont have any visitors.

maybe a badge huntsman as it has similar colours and strips along its joints

We do live in a "spider happy" place

We are lucky enough to live in a nature reserve in Johannesburg. We have lots of the wildlife here except for the big 5 or dangerous animals. Other than that we have different bucks, zebras, few giraffes etc.

It is really amazing to drive down a main road and you see zebras or the like. Of course they are behind fences but are totally visible from the main road.

Few years ago, even today, some people believed that lions were roaming our streets. We still have to drive a few hours to get to the real wild. Johannesburg is a major metropolitan area, so no wild animals running in the streets.

Over the last few years the nature reserve we live in fenced up and started bringing some of our wildlife smack in the middle. Still no big cats, elephants, buffalo or rhinos will be brought here.

This helps with the flora which gives us a lot more spiders than the average home in Johannesburg. But, trust me - the dangerous spiders will be found in any house in Johannesburg, nature reserve or not.

Can anyone identify this spider?

Hi all. This is the best pic I could get of Spidey. She spent all of last summer on our front porch. We had to stick to using our back door the whole summer as I didnt want anyone to break through her web which was stretched from one railing to the other effectively blocking the way to the front door. She also spent alot of time in a web in my picture window in my livingroom, so we could watch her, and she could "watch us". Anyway, I was wondering if anyone knows if she is a "safe" spider, or if any return this year should we move them to a new home at a park or something.

heres another pic. Hard to see but she was black with very light yellowish white stripes

Looks like the large garden spiders we get here. I have moved them out of doors and windows and placed them on out of the way bushes with mixed results. Sometimes they were back by the next morning and had to be moved several times befor they gave up. I only kill spiders that I know to be dangerous such as black widows and brown recluses. These are harmless and beneficial in that they eat so many pests and some people believe them to bring good fortune to the gardens they grace with their presence.

Thanks Zany, I knew she was special. LOL. My friends thought I was out of my mind when Id point her out to them, and mention how beautiful I thought she was.

I think there was another thread about these spiders way back. and they may have given an actual name for them but the old brain can't remember what it was!

Tig, those spiders are fascinating. Glad to see it doesnt look like spidey is poisonous, and her and her family are welcome to move in anyplace they choose (as long as its out in my yard. not in the house) Thanks so much for the link.

you're welcome:) we had a big one over the pond last year, I hope she returns.

Huggle see Nick's Spiders and try to get a closer pic. We might have to name this specie after you. The spiny legs are especially wierd. Try to see if it has a mate, or lays an egg sack. Not kidding, this might be a new one. Frank

Hi Frankay. These are the only pics I took of spidey last year. Hopefully her family will be back here this year, and I could get some more pics. I dont know anything about spiders at all. Is it possible shes still alive and her herself could be back this year? or if I see any of them would it be her offspring?

Can anyone identify this spider? - Biology

. and should I be worried that i've seen 4 of them in my house already in a 5 day period?

. and should I be worried that i've seen 4 of them in my house already in a 5 day period?

It appears to be a Haitian Voodoo Spider. This spider’s bite is almost, but not completely, fatal.

Probably escaped from a private collection of exotic creatures left behind after a foreclosure.

well people there ARE hobo spiders in the Portland metro area. --hobo spiders are relatively aggressive

its great to see that we have educated people from Oregon St University's agricultural dept among us.


Dear Cooperative Extension:
I have been seeing several (many) of a breed of spider that I have not seen before in our 13 years at our current home. They are light brown (tan) on most of the body, with a bold, darker brown stripe all the way down the back. They are large, estimated 1.5 inches from toe to opposite toe. Being a paranoid type of guy, I was afraid, at first, that they could be a brown recluse, but there is no resemblance of the brown stripe to a violin shape as the brown recluse is usually described. I have taken several pictures, as close up as I could get, and zoomed in as far as I could with my iPhone. 7 of the 9 individuals I have seen were in my pool, easily cruising (fast) along the top of the water.

Is it possible I could send a picture and have someone identify the species of this arachnid?

Thank you,

Wolf Spider

Most wolf spiders have stout bodies and long, thick legs. Their bodies are low to the ground even when walking or running, giving them the appearance of continually being on the prowl. Wolf spider species are similar in general form, but their bodies vary greatly in size, ranging from 2 mm (0.08 in) to nearly 40 mm (1.6 in) in length. They typically have two very large, forward-looking eyes in the middle of their face, flanked by two large upward-looking eyes, and a row of four smaller eyes below. Wolf spiders generally locate their prey by sight, but may also use touch to determine the nature of the prey. They use their front legs to grab prey, then bite and crush it with powerful jawlike mouth parts called chelicerae.

The female wolf spider lays eggs in a large sac, which can be nearly as large as her own body. She attaches the egg sac to her body, and carries it until the eggs hatch. She then tears open the egg sac and the newly hatched spiders climb onto her back where they remain for up to a week.

Scientific classification: Wolf spiders are members of the family Lycosidae, in the spider order Araneae, in the class Arachnida.

As its name suggests, the common house spider is the spider most often seen in homes in the United States. They like to build webs in hidden areas of the home, such as attics, basements, sheds, and barns. Most of the webs are in the corners of rooms and very easy to miss.

The common house spider is small, less than a quarter of an inch (0.6 centimeters) long. Females tend to be a little larger than the males. House spiders are brown and some individuals may have brown or white spotting on the abdomen. The legs of males have an orange tint, while the legs of female common house spiders look yellow. One of the most noticeable characteristics of the common house spider is the dark rings on the legs. Each leg has several darker rings, especially at the joints.

Common house spiders will live just about anywhere. They can be seen in gardens, backyards, basements, attics, barns, sheds, and any other type of man-made structure.

When people find common house spiders, they often destroy the web and kill the spider. However, it's important to remember that spiders eat insects, including flies and mosquitoes, and they could be keeping these out of the homes they're inhabiting.

Common house spiders spin webs that are made from thin silk strands. There are several ways to tell a common house spider's web from other species' webs. For one, common house spiders usually spin one part of the web to be thicker than the rest. The spider sits on this thicker portion of the web. In addition, common house spiders like to add a leaf or two to the web so they can hide.

Common house spiders might be seen on multiple webs close together or a web with more than one spider. If house spiders find a good spot with plenty of food, they do not mind if another spider produces a web nearby. However, if the webs are too close, the spiders might attack each other.

A female common house spider can produce several egg sacs in a year. The best time to spot an egg sac is in the summer. They are very small, papery, brown sacs that hang from the web and can have more than 400 spider eggs inside.

Common house spider populations are not considered threatened.

For a short period of time during the breeding season, males and females can live on the same web.


The species was first described in 1802 by naturalist Charles Athanase Walckenaer as Aranea agrestis, [1] in reference to its western European habitat in fields, woods, and under rocks. [3] In 1841, Walckenaer transferred the species to the genus Tegenaria. [1] In 2013, Tegenaria was split up, and the hobo spider was transferred to a new genus Eratigena, an anagram of Tegenaria. [1] [4]

Spiders, including the hobo spider, vary considerably in appearance, and identification can be difficult. The hobo spider is 7–14 mm in body length, and brownish in color. [5] Identification relies on an examination of the spider’s anatomy. Like many species of spider the positive identification of Eratigena agrestis requires microscopic examination of the epigynum and palpal bulb (the female and male sex organs respectively) and is best done by an arachnologist. However, the following characteristics identify hobo spiders among other species with a similar general appearance:

  • Hobo spiders lack the colored bands found on many spiders of the family Agelenidae where the leg joints meet. [6]
  • The abdomen has chevron (V-shaped) patterns (possibly many of them) down the middle, with the chevrons pointing towards the head. [5]
  • Hobo spiders have a light stripe running down the middle of the sternum. If the spider instead has three or four pairs of light spots on the lateral portions of the sternum, then it is one of the other two related Eratigena species. However absence of spots is not conclusive proof that the spider is a hobo spider, since the spots on other Eratigena species may be extremely faint and not readily visible. [6]
  • Hobo spiders do not have two distinct longitudinal dark stripes on the top side of the cephalothorax, instead showing indistinct or diffused patterns. Washington spiders with distinct dark stripes include spiders from the genera Agelenopsis and Hololena and possibly some wolf spiders. [6]

Eratigena agrestis is distributed from Europe to Central Asia, and is also found in western North America, in the Pacific Northwest and Great Basin. [1] It is recorded in the checklist of Danish spider species, [7] and is present on the small island of Peberholm, probably having been carried there by foreign trains. [ citation needed ]

It is a resident of fields, avoiding human habitations occupied by major competitors, particularly the giant house spider (Eratigena atrica), which is a common resident of houses and other man-made structures in Europe. As a result, human contacts with the hobo spider are uncommon in Europe. [8] Hobo spiders build a horizontal, trampoline-like web near brick walls or wood piles where the spider has shelter and awaits prey. [5]

Although the toxicity and aggression of the hobo spider have long been debated, there is little evidence that the hobo spider is a dangerously venomous species. [9] The CDC reported case studies in the 1990s claiming that the hobo spider bite caused isolated cases of necrosis in people, [10] [11] but as of 2017, the CDC no longer lists the hobo spider among venomous species. [12] In Canada, there is no evidence that hobo spider bites cause skin necrosis. [13] Some bites reportedly from the closely related desert grass spider, Agelenopsis aperta, may have been inaccurately reported and may have actually been from the hobo spider. [14]

The Myth of the Grandaddy Long Legs

According to popular belief, the granddaddy long leg is the most poisonous spider in the world. While the origins of this myth are unknown, we do know one thing for certain: granddaddy long legs are not spiders and they aren’t poisonous (or venomous for that matter).

Granddaddy long legs, also known as harvestmen, are often mistaken for spiders because of their spider-like appearance and movements. While they do have some spidery characteristics, they are not, in fact, spiders. They are classified as arachnids like spiders because of their 8 legs and movements similar to their spider cousins. Other arachnids that aren’t spiders include ticks, mites, and scorpions. Despite their appearance, granddaddy long legs are actually more like scorpions than spiders. Spiders have 8 eyes while granddaddy long legs only have 2. Spiders also have a distinct waist separating their thorax/head from their abdomen while granddaddy long legs have one fused cavity containing their head, thorax, and abdomen. Finally, spiders produce silk and spin webs. Granddaddy long legs do not produce silk so they can’t make webs.

Poisonous and venomous are often confused, especially when it comes to pests. Poisonous creatures cause harm through touching or ingesting. Venomous creatures cause harm through injection of venom. As far as humans are concerned, granddaddy long legs are neither poisonous or venomous.

Granddaddy long legs do have fang-like mouth parts (also known as chelicerae) that they use to grasp and chew food but they are not used to bite humans nor inject venom. These arachnids have developed some rather unique methods of defense from predators. First, they have a set of stink glands that they deploy to help ward off predators. They also have been known to curl up and play dead when disturbed. The most unique defense mechanism, however, is their ability to shed their legs when grabbed (also known as autotomy). Unfortunately, once they shed an appendage they are unable to grow it back.

Because they pose no threat to humans (and, in fact, feed on other smaller insects that may be in and around your home), you don’t necessarily need to get rid of them should you stumble across one. They prefer dark, moist environments and are often found in crawl spaces, basements, and garages. The best way to get rid of a granddaddy long leg is to sweep or vacuum it up.

Because what attracts granddaddy long legs are smaller pests they can prey on, seeing a large number of them in your home can indicate another pest control issue. If you suspect you have a pest problem, contact a professional pest control company who can help with pest and spider identification and the best course of treatment and future prevention.
