Harvestman from Scotland

Long legged spider / insect ???
Fri, Nov 21, 2008 at 5:27 AM
Dear Bugman
This creature is currently basking in the sun on the front of my new house wall. Location is central Scotland. Its legs are very long and almost create a fan shape. Its body is oval with a bit of hight to it and its legs resemble spider esk shape. We have fir trees at the back of the garden and I thought it might have come from there. I would really love to know what it is and if im likely to see more of them in the future.

Dear Mrs Brind,
We searched through 19 pages of images of Harvestmen in the order Opiliones in the hope of finding an example of an individual positioned like yours, but we were not successful. Harvestmen are related to spiders, but do not possess venom. They are harmless scavengers that are sometimes called Daddy Long Legs.

Hi Bugman and Mrs. Brind:
This looks like Dicranopalpus ramosus. Although harvestmen are quite harmless in a direct sense (to humans), this is apparently an exotic or ‘invasive’ species in Europe, so there may be some ecological implications. Apparently it originated in North Africa and has been spreading northward for some time, finally reaching Scotland in 2000. Because in is an invasive species there are quite a number of articles and photos on the internet. Wikipedia offers a brief summary at: http://en.wikipedia.org/wiki/Dicranopalpus_ramosus Regards.

Hi Karl,
We were unable to open the Wikipedia page you cited, but we did find another website with good images of Dicranopalpus ramosus and we found a posting entitled UK Alien Invasion on the UK Independant website.
Gradual species expansion like this is an often overlooked symptom of Global Warming.

Hi, I was just reading about the Harvesman which Pauline found in the Falkland Islands. I found some in my garden in Stanley yesterday, they are quite abundant, and I know I have found them before, also on outer Islands I Have found them, they seem to be widespread. Also there seems to be a couple of varieties, the back can be different, plain or fancy, the picture i have here you can see the pattern on the back of it. They look very similar to the ones found in Chile. This is just a follow up, I thought you might like to see it a little closer for identifying purposes.
Best Regards,
Zachary Stephenson.

Dear Zachary,
Thanks for sending us your photos of this unusual looking Harvestman. It is much more frightening looking than the typical North American Daddy Long Legs. Whether they are scary looking or not, Harvestman or Opiliones are harmless scavengers without venom.

Harvestman and Mites

Grandaddy Longlegs
Thu, Oct 30, 2008 at 6:23 AM
Dear Bug Guy, I know that this bug is probably very familiar to everyone, we called it the grandaddy long legs. There was a rumor growing up that if they could bite they would kill you, I never knew if that was true or not, but I never let one get close enough to bite. I saw this particular grandaddy on some wood we were putting away and noticed the little red things on it. Are they eggs, baby grandaddy’s or some other bug hitching a ride. I think their legs look like spark plug wires, I have never seen them this close. So, since we all know what we call these, what is their real name, and what are the little red things attached to it.
Thnaks so much,

Harvestman with Parasitic Mites

Spider carrying orange orbs
Sun, Oct 12, 2008 at 6:53 AM
I found this spider while digging a trench in my lawn in April, 2008. There was no web in sight. The spider seemed to be just walking along. My first thought was that it was carrying it’s eggs somewhere. I took a few pictures, then continued with my trench. After a few days, I began to wonder exactly what kind of spider it was and what it was doing, but haven’t been able to find out any more information. Thanks for your help.

Harvestman with Parasitic Mites

Hi TJ1028,
Your spider is actually another type of Arachnid in the order Opiliones, commonly called a Harvestman or Daddy-Long-Legs.  The orange orbs appear to be Parasitic Mites in the genus Leptus.  We originally thought the Mites were merely hitching a ride, a phenomenon known as Phoresy, but a search of BugGuide revealed the parasitic nature of the Mites.  There is some good dialog contributed by the BugGuide readership on the genus Leptus.

Hi Drew,
This is some species of Harvestman in the order Opiliones.  Harvestmen are sometimes called Daddy Long Legs, and they are related distantly to spiders.

Harvestman

What the heck is this?
I love your website. I have learned SO much while searching for this beetle/spider/tick looking thing. I took pictures the best I could. I’m sorry if they aren’t as clear as they could be. This little guy was determined to get back under the rock. We live in Arkansas, up on top of a mountain, and it is very rocky up here. My husband was clearing some of the bigger rocks out of the back yard when he found one of these yesterday. He didn’t get back to it in time to take a picture so he went back out there today and was able to find another. He was approximately 1 1/2" total, legs and all. His body looks like a tick with no visible head that we could find. It appears to have eyes up on top of the front of his body. I could even make out a smiley face when I looked at him upside down :) Yes, I have spent WAY too much time looking at the pictures of this thing. I have scoured your website trying to find what he/she is but haven’t found him yet. Can someone please help me identify it? I know you are extremely busy so thank you so much for any help that you might be able to give us. Thank you for the awesome resource you are providing!
Damon & Kristi Whitener
P.S. We didn’t kill him :)

Hi Damon and Kristi,
This is a harmless Harvestman. We believe we have found a match on BugGuide. It looks to us like Vonones ornata. You should submit your photos to BugGuide as they have not received any reports from Arkansas, though images of this genus have been submitted from surrounding states.

Harvestman from Brazil

what in the???
Yikes! My boyfriend’s friend lives in Brazil and found this walking around his apartment. I love the tropics, but I am glad I don’t have spiders like this just "drop by" unannounced.

Hi Lisa,
This is a harmless Harvestman in the order Opiliones. In the U.S. Harvestmen are known as Daddy-Long-Legs.

Crab Clawed Harvestman

spider help?
Hello,
I’m hoping you can help me idenfity this spider. I have seen many of them outside my home, thankfully none have made it inside. It’s probably about 2 inches at longest leg to leg and has what looks like fangs. Are they dangerous? I am panicked about black widows and brown recluse. I live in eastern San Diego county where it gets quite warm. Thanks!
Audrey

Hi Audrey,
This is a Crab Clawed Harvestman in the family Sabaconidae, and probably the genus Taracus. We located it on BugGuide. Harvestmen are also called Daddy Long Legs and they are harmless.

Harvestman from the Falkland Islands

Spider?
I found this in my garden, I live in the Falkland Islands, South Atlantic and these have not been seen before. There was 2 of them under a piece of wood (dry) which was at the bottom of a pile. The rear is the two hairy looking legs. It is dark and reddish brown in color. The body is about the size of a dime, 4 front legs. No wings. The other one was quite a bit smaller. Thanks for your help,
Pauline

Hi Pauline,
This is a Harvestman in the order Opiliones. We recently got an email from someone more familiar with this order, and we will contact Rod Crawford to see if he can confirm or deny or provide any additional information.

There are only 2 harvestmen recorded from the Falkland Islands: Haversia defensa (Butler) and Hoggellula vallentini (Hogg) both in the family Gonyleptidae. Your photo does indeed look like a gonyleptid but is not high-res enough to have any diagnostic features. I have on hand a drawing of H. defensa showing the hind legs less stout than in the photo, so by elimination it might be considered to be H. vallentini (of which I can find no illustration without making a special trip to the library) – but I don’t really stand by the accuracy of ID by elimination! from your friendly neighborhood harvestmanman,

Harvestman

A really charming Mystery "Bug"
Hello!
A care package of spiffy treats!!! (organic jams, delightful whole leaf teas, etc.)… …to whoever can relieve me of my obsessive and unsuccessful search for the identification of the delightful leggity being I photographed on a piece of Doug-fir firewood last spring. Attached. I named the photos "red spider boyee" as a mnemonic, not sure it is a spider. Is it a whipscorpion? Reminds me of the general vinegaroon body plan…and has that delightful flat lapstrake butt. It was under the tarp, dazed by the early morning light, and very shy. Nocturnal behavior. Also it was on the woodpile on our patio, which is frequently accessed. So must have come in the night. I took the photo then covered it back up. The growth rings on this Doug-fir chunk are maybe 2 mm each (red and yellow, each) so we’re talking about an overall bodylength of not much more than a centimeter. CUTE. I looked and looked and looked, normally able to find anything on the World Wide Web. But no luck. … I am writing from just outside Olympia, WA, in the rapidly suburbanizing wooded hinterlands of Pugetopolis. Thank you so much for taking the time to read this.

Hi Michelle,
This is a Harvestman in the order Opiliones, which contains the Daddy Long Legs. This particular Harvestman is in the suborder Laniatores. There are several photos on BugGuide from Oregon, but none from Washington. Using their raptorial pedipalps, Laniatores prey on small invertebrates. Are you really sending us a care package???

Update: Michelle received this more thorough reply shortly after our response
Dear Michele,
Your specimen is definitely a harvestman (arachnid order Phalangida or Opiliones) of the suborder Laniatores. It is a fine example of why arachnologists never use the term “daddy-longlegs”! The most likely species for you to have there is Sclerobunus nondimorphicus of the family Triaenonychidae. However, there is a remote chance of finding one of the old-growth obligate species of the genus Pentanychus or Isolachus (Pentanychidae). All these species look pretty much the same in top view, and in fact, dissection is needed for definitive ID. Harvestmen are chiefly predatory but can scavenge as well. Unlike pseudoscorpions they do not have the chelate, scorpion-like pedipalps. They have no silk or venom. In this particular group of harvestmen the palps are spiny. The two centrally located eyes are another thing that might tell you that it’s a harvestman, as well as the subsegmented leg tarsi. I’m amazed to find very little Sclerobunus info on the internet. However, Wikipedia has a bare bones illustrated article on S.robustus (which does not occur in western Wash.). S. nondimorphicus is so common here I have over 120 vials of them in my collection. The very small amount of published info on this species is in this paper: http://www.archive.org/stream/occasionalpapers90cali/occasionalpapers90cali_djvu.txt PS. I’d welcome any caffeinated tea. Don’t use much jam. :-)
Rod Crawford, Burke Museum, Seattle, USA

Dear Daniel–
I’m so excited!! I have a photo and letter published on WTB! This is better than the times my ex got two letters published in the Archie McPhee catalog, or when my husband showed the Dalai Lama his 3D tattoo! Opiliones! We LOVE those guys. I can see it now with your identification. The two eyes on top–duh. Rod Crawford at the Burke Museum (U. of WA Seattle), and Pugeopolis’s spider expert, also replied … You put in a lot of work on this site, I’ve read What’s That Bug? for years, it is one of my favorite-ever Web sites. If I had to give up all Web sites but one, I’d cry while surrendering /The Onion/…but I’d do it, for What’s That Bug? … But we still have a universe to learn about bugs. You do more for the evolution of the human spirit and mind than most churches. Wait, that’s not saying much. OK, never mind the comparison. You encourage people to evolve compassion and connection. You encourage respect and appreciation for our ancestors and neighbors. I love the site’s vilification of savagery against arthropods, and its the tone of affection and respect for these creatures, and affirmation of their beauty and importance. I love the way you lay it on the line around the stupidity of killing beneficial insects, and our need to face our silly fears and grow past them. I love the way you encourage the heretical belief, based on empirical evidence, that Nature Bats Last.
So of COURSE you get a care package. So–where are you? Strawberry, raspberry, apricot, citrus marmalade, or mixed berry? For tea–green? oolong? black? pu-erh? Need steeping instructions? How many of you ARE there? Iowa’s a big state. I know that, because we’re expatriate Cheezers. Peace

Harvestman from Baja

Bug identification
I was on a trip in Baja, and there were hundreds of these on the ground. I am a leader in an outdoor program and I would like to know what exactly these are for future reference. The attached picture shows a medium sized one (about an inch and a half long, excluding the longest leg). This particular one is missing a leg; there is normally one long leg on both sides. They did appear to have fangs, so at first glance they looked like spiders. However, they had no web, and were in large groups, so I’m not sure what exactly they are. Thanks!
Jason Payne

Hi Jason,
Your creature is known as a Harvestman in the order Opiliones. Harvestmen are sometimes called Daddy Long Legs and they are relatives of spiders that are scavengers.

Chilean Harvestman

strange spider from Chile
Hi,
I found this strange animal in the temperate rainforest of southern Chile near the city of Valdivia. Thank you very much for helping to identify this interesting creature.
Gerhard Huedepohl

Hi Gerhard,
This is not a spider, but a relative known as a Harvestman in the order Opiliones. Two years ago this month, we received a another quite similar image, also from Chile, and Eric Eaton provided this information: ” The Chilean “spider” is actually a tropical harvestman (order Opilones), possibly in the suborder Laniatores, and, even more remotely plausible, in the family Gonyleptidae. I got all this from my old Golden Guide to “Spiders and Their Kin” by Levi and Zim:-) Eric” Many Opiliones are known as Daddy Long Legs and they do not posess venom, hence they are harmless.

Hong Kong Mystery found in a Pet Shop: Some species of Harvestman

Unknown Pet
Dear Sirs,
I have just acquired my new pet in the attached pictures, please advise what are they and what they eat. Thanks a lot. With regards,
Alexander

Hi Alexander,
Please provide more details. did you buy it? Did you catch it? Where was it found?

(12/19/2007) Unknown Pet
Hi Daniel,
I’m from Hong Kong and I bought these guys from a local pet shop and the actual thing is he’s on the way on studying these guys and before he came into some answer, I took a pair from him and study them also. If you have any nice advise, then that’s great. Thanks a lot. With regards,
Alexander

Hi again Alexander,
Thanks for the additional informatin. We are totally mystified. Our best guess, and this is just a guess, is one of th Opiliones or Harvestmen. We will post your images in the hopes that someone can give us an answer and provide us with links to information online.

Confirmation: Eric Eaton confirms suspicion
Daniel:
It is some kind of tropical harvestman (daddy-longlegs), probably in an entire ‘order’ that isn’t found in North America.
Eric

Harvestmen are scavengers that feed on a wide variety of organic matter.

Harvestman: Suborder Laniatores

Legged Big Fanged Black Bottom
Bugman,
I live just north of Sacramento, California (USA) and I found this spider under a raised, wooden flower bed on my front porch. I was hoping you could tell me what kind of spider it is and whether those massive fangs could do me any harm. Thank You,
Jessica

Hi Jessica,
We are nearly positive this is a Harvestman in the Suborder Laniatores. Harvestmen are also commonly called Daddy Long Legs and they do not have venom. Your photos are totally awesome. We suspect if we are correct, Eric Eaton might ask permission to post this beauty on BugGuide as well.

Chilean Harvestman

chilean spider (?)
Hi Bug Folk,
My girlfriend and I were recently in Chile and saw a number of these spider-like creatures near where we were staying. They only came out at night and moved rather slowly…quite and interesting creature. Anyhow, if you know what it may be, let me know. Thanks for all your buggy wisdom!
Aaron Hilst

Hi Aaron,
Well, it has 8 legs and no antennae, so that implies spider, but we have never seen anything like it before. We will post the image and perhaps eventually get an answer. Eric Eaton wrote in with this identification: ” The Chilean “spider” is actually a tropical harvestman (order Opilones), possibly in the suborder Laniatores, and, even more remotely plausible, in the family Gonyleptidae. I got all this from my old Golden Guide to “Spiders and Their Kin” by Levi and Zim:-) Eric”

Daddy Long Legs

>Found this outside my house yesterday near my trash cans. It is fairly large
(inch+) and did not appear to have a web. I looked around the internet and was unable to find anything that had the same kind of odd front legs and body shape. I’m sure its nothing special, but my curiosity got the better of me. I live in Fairfield, California by the way. Any idea?
Chad Harden

Hi Chad,
Daddy Long Legs or Harvestmen are harmless relatives of spiders in the Order Opiliones.

Harvestmen

Daddy long legs
I have seen several references to the bug known as "daddy longlegs" and most of them say that this is not a spider, but a true bug.
The bugguide has them under arachnids and I just wanted to clear this up. My daughter is trying to identify bugs in her collection.
Thanks,
jeff

Hi Jeff,
What an awesome photo or Daddy Long-Legs or Harvestmen from the Order Opiliones. They are arachnids, and related to spiders, but are not true spiders. They have no fangs and do not bite. They use crushing mouthparts to feed primarily on the carcasses of invertebrates that have recently died.
