The larvae of each butterfly have a fairly strong preference when it comes to their diet. However, groups of plants that are desirable to a fairly wide range of butterfly larvae include willow, wild cherry, milk weeds, sweet bay, passion vine, legumes, crucifers, and asters. Many of the wildflowers that perform well in the southeast provide excellent nectar and larvae food. Wildflower seed mixes, developed by The University of Georgia, are commercially available and can be sown in the sunny meadow areas. This is an easy, low-cost way to enhance the food source for butterfly and larvae.
Wildflowers also provide natural areas that are low-maintenance and water efficient.
Another necessary ingredient for a sustained butterfly population is a source of water. Butterflies will not drink from open, deep water areas. Therefore, it is necessary to provide one or more shallow water sources. Wet sand or mud provide excellent watering holes. A rock or other object in the center of the saucer provides a resting spot for the butterfly.
