I don't have those, Linda. There must be a native plant somewhere they use, but I don't know what it would be. The adults that deposit the eggs must know, but I don't. They lay those tiny eggs one at time rather than in clusters. They are hard to see, but I have rubbed some off. Obviously not nearly enough. I'm going to have to move the container to a less visible location. It's already looking ratty. I like it until it's eaten to shreds. I plant it for the butterflies and then complain because they eat the plant! Go figure. I saw another adult fluttering around it, so it probably has a new crop of eggs. The foliage is disappearing so fast now that I wonder if the caterpillars don't consume some of the eggs.
