I think our are mutating. I find ones with no spots all the time, and last year I saw a yellow one. Just when i thought that was weird, there was a green one. And I've seen a couple of those. maybe they aren't ladybugs, but they're shaped the same and look the same except for the color. Someone said I was crazy,but I got a pic of one of them last year. I think it's on DA,but I'll look it up.
