I have a solid BRIGHT yellow almost florescent type "crab spider?" in my garden. It is on the big green leaves of my 8 ball squash plant, right next to my tomato plants that have small yellow flowers on them. I thought a tomato flower had fallen off they looked so very similar, But, when i sprayed it with water it moved and i saw the "petals" become legs. Just eyeballing it, it appears to be about 3/4 inch by 1/2 inch with legs appearing to be on the front portion of the body only. It has been there for a few days, I want to take a picture of it, if i can maybe i can send you a copy here, As I am not seeing this exact one in any pictures on the computer.
