This little lady was found laying in wait on some mounted plants. Due to her color, she is nearly invisible when she is curled up on the back of a piece of cork. On the front, she is more visible. I was unable to figure out what species she is, but due to body type and her habit of sitting down and folding her legs up so that she looks like a wee spot of mud on the cork tells me she is a crab spider. These are hunting spiders, like jumpers, and don't weave webs. Crab spiders are also often called flower spiders, as many species are colored to blend in well on flowers, and prefer to hide among petals to wait for a chance to catch bugs.
