Margaret, I don't actually get Clouded Sulphurs here (only Cloudless) but my Grandma gets them like mad when she doesn't mow and the clover (their host plant) comes up. Your picture certainly looks like the ones I've seen. I thought they would be about the same size as the Cloudless but they're quite a bit smaller. Who's naming these things, anyway?
Love that pink on the edge of the wings!
