Scorpion with Brood devours Wolf Spider

Dear Tanya,
You are our new hero.  These Food Chain images are awesome, but we have some questions.  Please tell us more about this Scorpion that appears to have been feeding indoors.  Was it living inside your home?  Also, the lighting is very different on the two images, with the redder image having more critical focus.  Why are the lighting conditions different?  We found a very similar looking Scorpion on The Flying Kiwi, but it is listed as unidentified.  Since the head of the spider has already been devoured, we didn’t think we would be able to identify your Wolf Spider, but we found an image on Scott Leslie’s site that looks very similar to the Wolf Spider in your images.  Alas, it is not identified beyond the family.  We love that you have supplied images to our site that document the maternal behavior of Scorpions.

Subject: Epic bug battle
Location: Wenaha-Tucannon Wilderness, Northeastern Oregon, in a river canyon
August 14, 2014 6:56 pm
Dear bugman,
In late April of 2009, my best friend and I went backpacking in the remote Wenaha-Tucannon wilderness of Northeastern Oregon, along the Wenaha river canyon. It was a spectacular trip made even more spectacular when it ended in near disaster; during a flash flood, my backpack with all of its photographic equipment was swept away and we narrowly escaped the same fate. Remarkably, the backpack was found one month ago by some hikers who pulled out one of the photo memory cards and brought it to the local sheriff, who tracked me down on facebook.
ANYWAYS, during the intervening 5 years, one of our greatest regrets about losing the photos was that we had witnessed an epic struggle between the largest spider I’ve ever seen in Oregon, and an enormous (for Oregon) long, cylindrical fly with a bright orange head that I had never seen before and couldn’t easily identify with online searches. We doubted anyone would ever believe how completely legendary and unbelievable the struggle was as these two titans locked themselves into a dance of death for at least 10 minutes. They did not care that we were there one bit. The battle was too fierce. We were able to get right up next to them with cameras and take photos….. and now we finally have those photos back! Unfortunately, my good camera with a macro lens was permanently lost, so the photos we have are only ‘decent,’ but I think they will work. I’ll be forever grateful if you can help give even more life to this newly revived fabled cha pter of my life by identifying these two mighty contestants.
Thanks so much,
John Felder
P.S. If it helps, I also have a low quality video – no fine details in focus but it give a better sense of the size because of the movement that’s visible.

Dear John,
If forced to choose which we are more impressed with, your amazing images or your fantastic story, we are going to have to go with the story, which is why we are featuring this posting on our scrolling feature bar.  The fact that you witnessed this “Epic Bug Battle” and then lost the images and then reclaimed the images after five years is truly an amazing story worth relaying.  The spider is a Wolf Spider in the family Lycosidae, and based on the size and eye arrangement (see BugGuide) we believe it is in the genus
Hogna.  The Carolina Wolf Spider, Hogna carolinensis, is found in Oregon, and you can see images of it on BugGuide which states:  “Considered to be the largest wolf spider in North America.” The Carolina Wolf Spider is also represented on the Spiders.Us site which states:  “This species is uncommon in the Pacific Northwest, but we have included those states in our range listing because it is still possible to find them there.”  We are going to check with spider expert Mandy Howe to get her opinion on the species.  The prey is a Giant Stonefly in the genus Pteronarcys, and it is most likely the California SalmonflyPteronarcys californica.  Here is an image from BugGuide.  One interesting note is that this sighting obviously occurred near the river, which is the correct habitat for the California Salmonfly, however, Spiders.Us indicates of the Carolina Wolf Spider:  “This spider is typically found in arid habitats such as deserts, prairies, glades, and open fields and pastures.”  Thanks again for providing your fascinating story for the entertainment and awe of our readership.  On a final note, we really hope we hear back from Mandy regarding the identity of this Wolf Spider because it may represent and new or little documented species as it was observed in such a remote location.

Hi Eric,
This is a truly amazing story with some wonderful images.  I’m not certain how good you are with Spiders, but since you lived in Oregon, I am hoping you can provide some input.  Can you confirm or correct the identity of this Wolf Spider:  Carolina Wolf Spider or other???  I have also contacted Mandy Howe.
thanks
Daniel

Eric Eaton Disagrees
Hi, Daniel:
Definitely “other.”  I’m not even sure there are any recent records of the Carolina Wolf Spider from Oregon.  Hopefully Mandy can put it to genus.
Eric

Ed. Note:  We are guessing that Eric agrees that this is a Wolf Spider, but not that it is a Carolina Wolf Spider.

Wow!  Thanks so much!!!!
I found the salmonfly online shortly after I submitted the photo and then I felt guilty for potentially wasting your time, so I’m glad you liked it!!!
A couple of things that add up based on what you’ve told me:
1) the habitat for Hogna Carolinensis:  the area around the Wenaha river is usually quite arid in terms of ambient humidity throughout the year and probably rainfall as well.  It’s the type of canyon that’s covered in dry brown grasses, rocks, and pine trees in the gulches but not on the exposed ridges.  In spring, the river swells from the melting snowfall of winter in the mountains, but rain is usually fairly sparse. EXCEPT for the week we were there, when it rained almost nonstop, causing the flood conditions and raising the river to probably historic levels.  So I think that if Hogna Carolinensis likes arid conditions, it probably likes the Wenaha area.
2). From what I’ve read, emergence of salmonfly larvae from the water tends to occur when rivers are at peak or rapid flow, which was definitely the case at the time we were there, further confirming the identity of the salmonfly.
I am going to send you a link to the (shoddy) video I have. Quality is poor but you can see their movements as they battle. Very compelling.
The hikers who found my pack were unable to open the rusted body of my metal dSLR to remove the memory card, so we unfortunately only have the lower quality images that my friend took with his plastic lower-megapixel point and shoot. Otherwise, we would have glorious, high definition, macro lens shots and video, but at least we have something.
Thanks again for the help and for featuring the story. You guys are great. I’ll send a link to the video when I get home.
Best,
John

Thanks for the update John.  We were under the impression that the images you sent were from the card retrieved from the missing camera.  Your most recent email indicates that you were always in the possession of the images.  Do you by chance have a dorsal view looking down on the top of the spider?

No no, your initial impression was correct.  I only just got the images this week after not having them for 5 years.
What I was attempting to convey is that there were two cameras in the missing backpack and the hikers who found it only retrieved the memory card from one of the cameras, which happened to be the poorer quality one.  If they had been able to get the images out of the other camera (they didn’t because it was rusted shut and they couldn’t get the memory card out and didn’t want to carry out the entire camera), we would have been dealing with better quality images.  That’s all.  The story, as it is posted on your website, is completely accurate.
Here are the closest I have to a dorsal view (focus not great):

Thanks for the clarification.  Bummer:  Too bad they didn’t bust the camera body to get the memory card.  Thanks for providing the dorsal view.  We wanted to be able to show the markings on the carapace.

Subject: Huge crab-shell shaped spider in Ecuador’s Andes Mountains
Location: Cuenca, Azuay, Ecuador (Andes Mountains)

A few months ago while on a hike in the Andes we spotted a large spider hole – with this huge spider inside. The crab-shell shape was a first for us. One of our readers suggested that it’s a Ancylometes (giant fishing spider).
We have a video of the spider in the url below – and we would love to know something about it.

Hi Bryan,
Based on the eye pattern (see BugGuide), we believe this is a Wolf Spider in the family Lycosidae.  Large individuals might bite, but they are not considered dangerous.  Perhaps one of our readers will be able to provide a comment with a genus or species name.

Subject: Massive wolf spider?
Location: Bloomington, Indiana
March 30, 2014 1:45 pm
Hello! I found this massive spider back in October of 2007, in Bloomington, Indiana. I thought it was a plastic Halloween toy at first because it was so huge, but when my dog stepped on it (hence the missing leg) it ran, and I realized it was the biggest spider I’d ever seen in person. I tried to identify it, but couldn’t find a spider that had both an orange stripe and banded legs. My pictures are a little grainy since they were taken on an old cell phone camera, but the head-on one seems to show at least one huge eye. Also, for size reference, my shoes were a size 8! Thanks for reading and I hope you can identify this spider I’ve been wondering about for years.

Dear Marina,
We believe your Wolf Spider might be in the genus
Hogna, which include the largest North American Wolf Spiders.  See BugGuide for images from the genus Hogna.  We will try to get the opinion of Spider expert Mandy Howe.

Immediate Update
Continued searching led us to this image of
Tigrosa aspersa on Bugguide, and we believe it is a perfect match.  According to BugGuide:  “ Hogna(Tigrosa) aspersa females are 18 to 25 millimeters in length, and the males are 16 to 18 millimeters. They are similar to H. carolinensis in body color but have a distinct narrow line of yellow hairs on the carapace in the vicinity of the eyes. The legs are banded with a lighter brown color at the joints. The males are much lighter in color than the females, and only their third and fourth pairs of legs are banded with a lighter color.”

Thank you!
Looking around on BugGuide, I think it might be in the Tigrosa family (maybe Tigrosa aspersa?) which used to be a part of Hogna, from what I can tell. This looks very much like it.
~Marina

Ah, looks like our emails crossed paths! Yes, I think that’s exactly it. Thank you so much! It’s great to know what it (she?) finally is.
~Marina

Based on what we have read on BugGuide, we believe this is a female spider as they are considerably larger than the males of the species.

Confirmation from Mandy Howe
Hi Daniel, sorry about the late reply again — but yep, I think Tigrosa aspersa is spot on for that female wolf spider. :-)

Hi. Spotted a ground-dwelling spider in the yard today (see attached photo) and am curious as to what type.
Closest I can tell it could be a Funnel Weaver, Fishing Spider, or possibly in the Wolf Spider family.
Looking forward to your insightful findings.
Thanks!

Dear C. Neil Scott,
We believe this is a Wolf Spider, but our second guess would be Nursery Web Spider which allows for the possibility of it being a Fishing Spider.  Your spider bears a resemblance to the
Gladicosa gulosa that is pictured on BugGuide.  We are going to contact Mandy Howe to see if she can assist in the identification.

Wolf Spider with Spiderlings

Hi JP,
Your request arrived just prior to us leaving the office for a spell, and that is something we are doing again soon.  We postdate letters to go live in our absence, and we do not answer mail while we are away.  We apologize for the tardy response, but we figured that since this Wolf Spider sighting was not an isolated event, you might still want to know the answer.  Wolf Spider are considered harmless.  They are hunting spiders that do not build webs to snare prey.  The common name comes because of the way they pounce on their prey.  This is not a guy, but a gal.  Female Wolf Spiders are very maternal.  They drag their egg sacs with them and when the eggs hatch, the young Spiderlings crawl onto the female’s back and ride around for a short period of time before dispersing.  If you look closely, you can see the Spiderlings in your image.  This may be a Rabid Wolf Spider,
Rabidosa rabida, which is picture on BugGuide.  Once again, despite the name, this is a harmless, local species for you.  Your request will post live to our site next week.
