Comments & ID Thoughts

My first guess was that this might be a baby Wolf Spider because I know they are present in my area, and this one is very quick, aggressive, and is taking down green/yellow sac spiders with ease.

After taking and looking at this picture, I'm not so sure...I didn't see any pictures of baby wolf spiders online that were as 'Grey' looking as this one is. That being said, I'm 'pretty sure this isn't any of the orb weaver spiders around here - I have seen plenty of them, and even at a young age they are never as flat. This spider, even at this size, demands respect, not only from me, but from other spiders. It will surely grow up to be a danger to anthing around it. Not just because of its quickness, but also because of its aggression and ease in taking down the most aggresive spiders in this area. That's just my opinion of course, but is based on observation.

The spider is very flat, meaning from its belly to its back is the shortest distance I have ever seen on a spider. It's as thin as a piece of paper...well, almost. This is a baby version - I am guessing anyway, it is less than 1/2" from the tip of any of it's legs to the tip pf any of it's other legs.

I have seen 3 or 4 of these in the last year, all on my house, never in a web. Also, almost all sightings have been in the daytime. Light outside. And all have been this size.
