I live in California, but a friend of mine on the internet lives in Australia and sends me pictures of various critters that live there, including this Australian spider. We were talking about spiders one day and he mentioned that the spiders where I am at are NOTHING compared to the big beast spiders he has there, and according to the picture of this monster spider, this seems to be true. He couldn’t tell me what kind of spider, but he said I could use this photo he sent me to find out. So what kind of terrifying beast spider do we have here? I can tell this thing is angry too…..The fangs on this thing are incredible, I think I will have nightmares for the rest of my life…..O_O;

Male Funnel Web Spider

Male Funnel Web Spider

Dear Brittany,
Australia has several spiders that are considered especially dangerous.  We found a nearly identical image on the Australian Spiders website and it is identified as a male Funnel Web Spider,
Atrax robustus.  The Australian Spiders site indicates:  “The Sydney Funnel-web Spider (Atrax robustus) is one of 36 species of funnel-web spiders in Australia (and it’s the only one that causes trouble).  Funnel-web spiders prefer moist cool habitats and you find them in the south eastern regions of Australia. They live in silk lined burrows and crevices. Their hideouts can easily be identified by the characteristic trip lines radiating from the entrance of the burrow.  The Sydney Funnel-web Spider is mostly found within a radius of 160km from Sydney. (There have been occasional sightings a bit further away.)  It is large (up to 4.5 cm for just the body), black, aggressive, and has powerful fangs.”  The site also states:  “The male Sydney Funnel-web spider is the most dangerous of the Australian spiders. (This is unusual. Normally the female spiders are more dangerous). Actually, I’d say it is the only Australian spider that can be called dangerous at all.”  According to the Australian Museum website:  “Sydney Funnel-webs are shiny, dark brown to black spiders with finger-like spinnerets (silk-spinning organs) at the end of their abdomen. Males have a large mating spur projecting from the middle of their second pair of legs. If threatened, Sydney Funnel-webs show aggressive behaviour, rearing and displaying their impressive fangs.”  The spinnerets are prominently pictured in the image you provided.

I shot this spider on the small island of Hajo-Do, at the far south-western edge of South Korea, in June or July 2011. From comparing it to images from google, it resembles a Wolf Spider, to my untrained eye, but I have also read reports that the Funnel Web Spider has somehow found its way here, and this spider had a funnel shaped web. (If it was the latter, I was courting disaster, as my hands were only a few cm away as I adjusted my lens…) So, I’ve supplied 2 photos – One from a little further back, showing the web, and a second, much closer, getting down to macro detail.
I’m a very keen macro shooter, and am especially crazy about bugs, although my knowledge of genus etc is very limited. Feel free to explore my blog posts on my macro work on insects, and any help with identifying them would be very much appreciated.

Spider from South Korea

Funnel Weaver from South Korea

Dear richarquis de sade,
We do not recognize your spider, and we do not have the time to research at this moment, so we are posting your excellent photos in the hope that one of our readers can provide a comment as to its identity.

Unknown Spider from South Korea

Funnel Weaver Spider from South Korea

Hi Daniel and richarquis de sade:
I believe your spider is a Funnel Weaver (Agelenidae), probably in the genus Allagelena. At least three species are native to Korea: A. opulenta, A. donggukensis and A. difficilis. All three species are highly variable in appearance but I did find several images posted by Daniel Ruyle of A. opulenta spiders from Japan that look very similar to richarquis de sade’s spider. Allagelena opulenta is native to China, Korea, Taiwan and Japan.  I tried to find out if it was considered dangerous to humans but my search was inconclusive. One site did indicate that its toxin is “insect-selective”, suggesting that it is probably not dangerous. However, I would probably not be inclined to test this if I was ever confronted with the opportunity. Agelenid spiders are sometimes referred to as Funnel Web spiders but they should not be confused with the very dangerous Australian Funnel Web spiders, most infamously the Sydney Funnel Web, which belong to a different spider family altogether, the Hexathelidae. Regards.  Karl

This fellow has set up camp inside my kitchen window. While I find it interesting to watch him catch his food, I miss having an open window. Can I safely move him to the back of the yard? What is he?

Grass Spider

Grass Spider

Dear Sally B,
We believe because of the prominent pair of spinnerets, that this is a Grass Spider in the genus
Agelenopsis, as pictured on BugGuide.  According to BugGuide:  “Agelenopsis spp. spiders are “lightning-quick”; often people only get a glance of it before it disappears behind or under something” and “These spiders are docile and non-aggressive. They will flee at the first sign of a threat and will not bite unless they feel threatened without an option to escape. (e.g. – Trying to pick the spider up).”  The best way to relocate the Grass Spider is to trap it under a glass, slip a postcard under the opening and transport to a more suitable location.

Dear Bugman,
It was the 3rd night in our new house when thought that our cat had nabbed a mouse. To our (Amityville) horror, we realized it was no mouse, but some sort of terrifying, prehistoric spider. We were able to trap him under a pint glass and snap some shots. The opening of the pint glass is almost 4 inches (3 3/4”?) and there is a slight glare on the glass. Nobody seems to know what this guy is! Some guess hobo, others say too large. It’s the creepy Black Metal type markings that don’t seem to match up with any breed. Upside down cross? Mariner’s fan? Possible Hybrid? Prehistoric creature?
Can you help identify, so we know what we are up against? The house had sat unattended for only a few months before we moved in.

Giant House Spider

Dear Frazzled Francine,
We don’t know what species of Spider you photographed, but your letter amuses us to no end.  We will post and feature your photo in the hopes that our readers will provide comments, suggestions and possibly an identification.

Giant House Spider, according to Karl
Hi Daniel and Frazzled Francine:
The photo is not very clear so I am not certain but I think this is probably a Giant House Spider (Tegenaria duellica = T. gigantea), a Funnel Weaver in the family Agelenidae. It is a European species that has been established in the Pacific Northwest and southern BC since early in the 20th century (I believe Canada can be blamed for this accidental introduction).  It is closely related to the smaller Hobo Spider (T. agrestis), another introduced European species that has acquired a reputation, that may or may not be deserved, for causing injurious bites to humans. Although the Giant House Spider is certainly capable of inflicting a bite if provoked, it is considered to be non-aggressive and not dangerous to humans. The dorsal markings on the abdomen are variable but I found several images that resemble yours. There is a lot of online information if you want to read more. Regards.  Karl

Thank you! Fantastic! Just to be clear; not dangerous? I’ll take a blistery, swelling bite over a fatal bite anytime!

*URGENT*~Brown Spider with Black Stripes~PLZ IDENTIFY~*URGENT*
Location: Columbus, Ohio, USA- near cut firewood in the back yard
September 20, 2011 12:15 am
Dear Mr. Bugman, I live in Columbus, Ohio & I just moved from the west side (Hilltop) to the north side (easton) area. Right outside my apartment at night on the 19th of September, almost midnight I went to sit on my step to smoke, since I do not smoke indoors. I actually seen something kinda looked balled up but in the dark I really couldn’t tell so I actually kinda scooted it off my step with my bare hand. I thought nothing of it & continued on smoking my cigarette & entered back into my house. Going out a second time to smoke, this time I turned the porch light on & right where I had kinda flicked the thing was a big, nasty looking spider. There is a big wooden stand that holds cut firewood right on that side of my door, in the back yard. This spider was bigger than most I have seen around here, in my house as well as from what I have ever seen around the Hilltop. So, naturally I am looking for markings immediately. I have been bitten by a nast y- poisonous spider before & it has left it’s mark on me permanantly. I have the scar till this day, not a pretty memory I care to remember or even admit. So, I do have some fear. However, I also have what I call ’population control’ around my house; which is where I determine by the size, quantity, location, & just pure looks which spider I shall allow to live on, in, & around my house. If these spiders do not meet my standards of ’safety versus benefits’ I am sorry to say, they must die & I take them out immediately. Most of the time- a shoe, sometimes the occasional death by being flushed down the toilet or rinsed with water down the sink, shower or bath. Anyhow, this spider out back of my new house has me worried & I cannot quite put my finger on what type of spider it is. Before I should decide this spiders fate, I am trying to give it the benefit of the doubt here. I need your expertise… It is brown, slightly hairy but not too much though. It has what looks like 2 black stripes from his head down his back to the very end of him. I did notice on his (but) area, it looks as if whatever those things are, (two somethings) maybe his spinners or what he uses to make his web, but they look rather long or protruding. I have never seen them so defined on other spiders before. They are easily recognizable on the end of the back of his body. I cannot see his face though. Just 2 black stripes from what looks like end to end. Please, if you can help me with the identification of this, I almost want to say beast because he is sooo scary… but of this creature. I would greatly appreciate it. I think from the pictures I have seen, I would say he is either a ’Wolf Spider’ or a ’Grass Spider’. To me, he does not match perfectly with either. I am concerned because of my kids. They play in this yard as well as walk in & out of that door when needed. The difference between the two spiders I mentioned are extremely important. From what I have gathered a ’Grass spider’ can be very poisonious? A ’Wolf Spider’ doesn’t look too pleasant either. so, if you would ever so kindly please help me, I will forever be ever grateful to your cause & your generousity. thank you kindly, with love from The Hall Family……Sincerely, Lilly Hall
ps. It is the beginning of Fall here & it did just rain today. When I went back outside to see if I could get better quality pictures. I went to take a picture of the web it spun inbetween the wood logs & discovered another one already. Now, Im freaked out there is a whole family out there. Also, I caught a slug, worm & God only knows what else all these bugs are- coming from underneath my step. It’s like a jungle out there. AHHHH, somebody help me. Then I remembered it did rain…. I sure hope the pics are good enough to help u indentify the species. I took it from my 3.0 megapixel Samsung rogue cell phone. You can always zoom in on it,especially if u have some good software. I am sorry I didnt have a better camera. thanks for listening. Plz email me back, thx so much….

Spider

Dear Authentically, I’m not sure I understand. Please, by any means you wish. whichever way is best I would guess. thank you. sorry I do not understand what this is asking….,
Our staff is speechless.  If the spider spun a web that looked like a funnel with a retreat hole, then it is most likely a Funnel Web Spider, a family that includes the Grass Spiders in the genus
Agelenopsis.  If it hunted without a web, it is most likely a Wolf Spider.  Any Spider might bite if provoked or carelessly handled.  Some people might be allergic to the bites of certain Spiders because not all spider venom is the same.  If you are nervous about Spiders and other bugs, we suggest you get rid of the wood pile by the house.  In our opinion, smoking is a bigger threat to your health than either spider.

Large Tegenaria, not sure what type
Location: Nova Scotia, Canada
October 30, 2010 7:51 pm
Saw this spider outside my house Oct26,2010 late fall in Nova Scotia, Canada.
Very large spider for these parts, body 1.5cm long, tip to tip from legs was around 8cm.
I think its a Tegenaria but not sure if its type is a atrica or duellica

Funnel Web Spider

Dear junponline,
We agree that this is a Funnel Web Spider in the genus
Tegenaria, but any attempts at our making a species identification are purely speculation.  Our guess is the Giant House Spider,Tegenaria gigantea (synonym for Tegenaria duellica), though there are a few snags in that line of possibility.  This is a European species that was introduced to the Pacific Northwest along with several other European species, including its relative the Hobo Spider, Tegenaria agrestisBugGuide does not list Nova Scotia as a sighting location, and all sightings are confined to the west coast.  The physical description of the Giant House Spider on bugGuide is “No banding on the legs, but proportionally longer legs than its cousins T. agrestis or T. domestica” and that fits your spider.  BugGuide also indicates:  “The greater European house spider (T. gigantea) is not dangerous to people. Some people may be intimidated by their size as male legspans can reach 4 inches (100 mm). However, Rod Crawford has never known one to bite a human (though they certainly could if they tried); they are so docile he uses them as hands-on demonstrators for school children.  You may want to post your photo to BugGuide to see what their large group of contributors has to say, because this may prove to be the first eastern report for the Giant House Spider.
