I decided to take a little walk down my road Saturday evening when I noticed a bee just clinging to this vetch and not moving. I thought it was kind of odd so I looked a little closer and this is what I found. The crab spider lies in wait on flower blossoms and ambushes an insect like this bee when it comes along. They also have the ability to change color, they can go from yellow to white. I've seen them on daisys in their white form and on black eyed susans in their yellow form and they blend right in. It seemes like this guy was in transition, between yellow and white. Either way it really wouldn't blend in well on a purple flower. The sun was real low and this shot was highly backlit so I used my foil reflector to add light otherwise it would've just been a silouhette.
