The herb fennel will attract the entire life cycle of the black swallowtail butterfly. It will host eggs, caterpillars and the chrysalis. You can plant clumps of fennel in your flower garden and the plants will host the the life cycle of many kinds of butterflies.
If you remove a branch of the fennel with a mature caterpillar... you can put it in a jar and watch the chrysalis form and the swallowtail emerge. A great project for kids!
