We ended up with 23 beautiful monarch caterpillars munching away on our milkweed. They devoured several plants and were still hungry. After calling a few local nurseries we located a few more young plants. We now have every variety of milkweed monarchs like in our yard. Luckily, some of the seed pods were munched only a little, and they have seeded the yard. This plant, which was completely chewed down, is also already sprouting fresh, new leaves.
