Thanks, everyone! Joshua, the markings are clearly in the leaf, not on the surface as would be by damage. The pink ones I'm looking at are on the Gilbert Wild website; I will go back on it to see if they list the parentage. I will remove my orange ones. Wouldn't you know it, they are the most vigorous lilies I have, next to a dark red noid asiatic? I did have an oriental whose flower looked weird last year, all crumpled up. I will remove that one, too. And I will stay on those aphids! I have never seen the number of aphids like I had last year, I had them on my tomatoes, my lilies, and my milkweeds, three different kinds, because they came in three different colors. I used soap spray on them because I am organic. I don't like to use Neem oil in the middle of the summer because of my summer heat; the aphids arrived in mid summer, and the temps were already in the 90s.
