Comments & ID Thoughts

I found this today when I was clearing up some junk we had stacked by the shed. I'm based near the Miravalles Volcano in the North of Costa Rica. It has a sack of eggs it carried around, and moved very fast and jumped up and down as it went. I work with a lot of tourists so would be good to know if it's one to look out for!

Hi, welcome to Spider ID. 🙂 This looks like a Wandering Spider (Ctenidae), Cupiennius sp.. The only Phoneutria in your range is P. boliviensis https://www.flickr.com/photos/andreaskay/35195442555. Your spider is in the same family but a different genus and doesn’t have the same reputation of being medically significant. Good to be mindful of them just to be on the safe side though, everyone’s immune system is different.
