Ant Mimic Jumping Spider - Myrmarachne formicaria - Male

I found this cool jumping spider crawling on my arm while out on a hike last weekend. Looks very similar to another that a naturalist friend found in Twinsburg, OH recently.

I have found today that is like ant but really it is a spider.interesting.

I found one of these yesterda
I found one of these yesterday in Oneonta, Alabama. I had no idea these were anywhere around here. I wonder how long they have been living in the states.
I may try to upload a picture of it if I can.

I know this is an older post but my sister and I found a male one of these in our bathroom tonight and never would have figured out what it was if not for your post! I live in North-Western PA and I've never seen one of these before now and was at a loss as to what it was. We both immediately knew it was some type of ant mimicking spider by the overall look of it and the fact that it dangled by a web at one point, but I was astounded by this because I had no idea that there were ant mimics outside the tropics. As cool as he was though I'm a little unsure whether or not I should have let it go instead of killing it since it is an invasive species from Europe. I would have felt bad squashing him but an invasive species can really do some awful damage to an ecosystem that it doesn't belong in.

Trap-jaw ant mimic?

Hi, I have lots of these spiders at my new home in Northwestern PA. Wasn't sure what they were until I searched the internet. Even the bug exterminator at work didn't know what I was talking about!!

This is definitely Myrmarachne formicaria. Great catch!

An awesome shot of a weird looking spider. I found some similar looking ones here, but not sure we have any of these in the US.

Normally I would have brushed off any bug crawling on my arm, but somehow I managed to resist the reflex and checked it out first. It's amazing how ant-like it looks. Nature is so astonishing!

Here's more info
"Abstract: The large genus Myrmarachne (Araneae: Salticidae) includes over 200 species, with representatives on each biogeographic region except the Nearctic. A population of Myrmarachne formicaria has been discovered in northeastern Ohio. There is reason to believe that this species, which is widespread in Europe, is a recent accidental introduction to this area. This species seems to be well established, having been found with increasing frequency over the past three years. A resident of Warren, Trumble County, Ohio first reported noticing this odd ant-mimic around her residence during the summer of 2000. The first specimen record was obtained from the same locality on 16 August 2001. Subsequently, specimens have been found in neighboring Portage County. The species appears to be common in a variety of situations, including occasionally inside buildings. (Added 6 / 17 / 2003)" From written by Richard Bradley.

ant like spider
We bought this house in Dec.2006 in conneaut ohio. Just this summer we started finding these spiders around the house. We have found about 6 to 10 of these,all seem to be males. I didnt know what they were so I caught 2 of them and put them in a ziplock bag together. They did some kind of wierd dance and then their jaws came open. That was really amazing to see.When we first found these we thought they were ants.Then we found one haging from a light by a thin piece of web.
