Butterflies and Moths — Butterflies and moths can be difficult to find, but looking for known food plants makes the task easier. Different swallowtail caterpillars eat parsley, dill, citrus leaves and sometimes carrot greens. If milkweed grows in your area, monarch caterpillars will be on the plants in the spring or summer.
