Hello Daniel:
I continue to check your site regularly (still one of my favourites) but it’s been a while since I offered something for posting. I have been photographing a lot of spiders recently and have developed quite a fondness for wandering spiders (Family Ctenidae). I always look for them when we travel down to Central or South America. They are not hard to find but you generally have to look for them after nightfall. The attached photo is of a wandering spider (Cupiennius salei), one of many encountered on a night hike in a forest near Punta Gorda, Belize, earlier this year. I had already taken one to two photos of this one when it suddenly lunged out of frame to capture this hapless, and somewhat surprised looking, cricket. Have a great summer.

Hi Karl,
Thanks for allowing us to post your excellent image of a Wandering Spider,
Cupiennius salei.  The species is pictured on iNaturalist.

Any idea of what Genus this spider this is? Found in costa rica in October…

Wandering Spider

We believe this is one of the potentially dangerous Wandering Spiders in the family Ctenidae based on this Photographers Direct image.

Thank you for answering! I’m surprised that we didn’t stumble around more dangerous things. We did find a poison dart frog and a monkey skull that fell from a tree…

Hey Its Carl again from the night walks in the cloud forest Ecuador, could do with some help identifying the family and species of this spider.
Also struggling with this larvae and praying mantis.

Dear Carl,
We believe, though we are not certain, that this might be a Wandering Spider in the genus
Phoneutria, and you may read more about Wandering Spiders on the Museum für Naturkunde Karlsruhe website where it states:  “There is no doubt that the venom of some of the species is quite potent for mammals, including humans.”  We eagerly welcome additional opinions on this identification.  Perhaps Cesar Crash of Insetologia can provide something.  In the future, please submit a single species per submission form as it makes it extremely difficult for us to categorize postings with multiple species.

Last year I posted an image of this species looking for an identification. In April I was back in Ecuadorian Amazonia and I spotted another of these beautiful orange spiders with bluish legs. My guide, a Shuar indian, said it was a crab spider. This was one of your answers in 2011. I was able to capture the eyes this time.

Orange Huntsman Spider

Hi John,
We will link to your original posting.  We decided to do some additional research.  First we located this YouTube video identified as being in the family Sparassidae, the Giant Crab Spiders.  Then we located this photo on FlickR identified as a Wandering Spider in the family Ctenidae.  Then we found this FlickR image identified as a Giant Crab Spider in the genus
Sadala, and finally, we found the same photo with the same identification on FlickRiver as part of the Bigal River Conservation Project in Northeast Ecuador. 

Daniel,
Did you reach a conclusion?
One problem in the jungle is the lack of good reference materials. An anima’ls name could be passed from one guide to the next (or one generation to the next) with no way to verify the knowledge. When one uses a term like “wandering spider” it seems very general.
In the end, this is one of the most beautiful spiders I have ever encountered. Just curious.
Thanks,
John R. Anderson

Hi again John,
We are more inclined to speculate that it is the Giant Crab Spider or Huntsman Spider family Sparassidae.  As far as verifying the genus
Sadala goes, both sources can be traced to the same original so there is no verification.  In our opinion, you should seek assistance from an expert if you want to confirm any identification.

Karl provides some information
Hi Daniel and John:
Since this lovely spider has made another appearance on your site I felt compelled to give it another go. It is not difficult to find images of this spider on the internet but finding information that is useful for identification purposes has proven to be very frustrating. In addition to the three possible families that have already been mentioned in this and the previous post I also found one site with two photos that looked like they were probably of the same spider, but suggesting it was a Running Crab Spider (Philodromidae). I chose to ignore it and pressed on. I eventually came up with genus Olios, a Huntsman Spider in the family Sparassidae (by the way the eyes in this second posting do look like Sparassidae to me). You can check out online photos identified as Olios sp. here, here, and here. I found several others as well but I was having trouble with the hyperlinks. I checked out several spider lists for Ecuador and it appears that there are two species of Olios in Ecuador, O. corallinus and O. niveomaculatus, but I could find no photos or useful information for either. Until you get confirmation from a real expert, I hope this helps more than it confuses.  Regards.  Karl

Thanks for your research Karl.

Ecuadorian Spider

I spotted this spider during a night hike near the Cuyabeno Wildlife Reserve in Ecuador. The length of the body was about 1.5”, and fore leg tip to rear leg tip about 3”. The bright coloring certainly indicated ”stay away” to me. The legs appeared slightly blue under my flashlight. The body is a reddish orange.

Huntsman Spider

Dear John,
This is a beautiful Spider.  We believe it is a Huntsman Spider in the family Sparassidae, also known as Giant Crab Spiders. Huntsman Spiders do not build webs and many are nocturnal hunters that wander about in search of prey.  Most Huntsman Spiders are harmless, though their large size often induces fear when they are encountered.  It is our understanding that there are some dangerous venomous South American Huntsman Spiders, and the aposematic warning colors on this specimen may indicate that it is a highly venomous species.

Karl provides some insight
Hi Daniel and John:
What a lovely spider! It’s too bad the eyes aren’t visible as they are often the best way to determine a spider’s family. It has been said often on this site that you can’t trust everything you find on the internet when it comes to bug identification, and here is a good example of why that is sage advice. I thought I was on the right track when I found this image of what was identified as a Wandering Spider (Ctenidae), but the trail soon grew cold and I got suspicious. I little more searching turned up this promising photo of a Huntsman Spider (Sparassidae), but again I could find nothing more to confirm that this was the right beast. Finally, I came across several photos suggesting it belonged to the family Platoridae. In this case, however, I couldn’t even confirm that this family still exists, with several sites suggesting that it had been dismantled and re-distributed among several other families (e.g., Trochanteriidae). If I had to choose I would probably favour a Wandering Spider, but this is going to require a lot more expertise than I have to offer (and I have to run and pack for Mexico, with bugs and spiders on my brain). Regards. Karl

Roatan Honduras Spider? Crab?

I snapped this photo of what I thought was a huge spider on Roatan Honduras. The local told me it was a crab, not a spider. Any ideas?

Possibly Huntsman Spider

Dear Laurie,
It is impossible to be certain because of the angle of your photograph, but we believe this is a Huntsman Spider, possibly
Heteropoda venatoria.  It is not a crab.
