Colorado Spider
Hello,
I found your website via a Google search. I recently moved in to a townhome in Loveland, Colorado. There’s a retention pond within about 30 feet from my front door and an undeveloped open space to the east of my home. I found this spider crawling on my textured sheet-rocked walls. I snapped this picture before I relocated him to the great outdoors. Any idea what it is? I looked through all 6 spider pages on your web site and never really found a perfect match. Almost looks like a fishing spider… Thanks for a great site!

Hi Rod,
This is some type of Giant Crab Spider. Here is the input we got from Eric Eaton: ” Don’t think the sprawling crab spider is a Selenopidae. From what I understand they are essentially walking pancakes, and this specimen looks like it has more depth to it:-) Plus, I read somewhere that philodromid crab spiders have the second pair of legs longer than the first pair, which seems to fit here. Philodromids rarely exceed ten millimeters in BODY length, though, so if it was larger than that, it could well be some other family. The experts really split up a number of the old spider families and I’m not caught up yet!”
