If those are lily leaf beetle
If those are lily leaf beetles, they are really easy to control if you can get the first adult generation who have overwintered every year. It's their offspring that do all the damage. I put a note in my calendar to start looking for the adults the first week after our last frost date. I usually find 2 or 3 pairs of adults mating on the very tops of the plants. Squish those few couples before they manage to lay eggs and you're safe for the year. (They are a non-native invasive, so don't feel guilty about giving them the squish.) At this point in the year, you can just pick any leaves with larvae on them and bag them up for the garbage. Spend a few minutes every day for a week checking your plants and you'll win the war.

Thanks! That's really helpful
Thanks! That's really helpful. They really are horrible and they may have damaged too much of this lily, but the others are still OK. I'll keep on it with them now that I know.
