Basking spots. Help butterflies catch some rays by placing large flat rocks and stepping stones in sunny spots so they can perch on them.
Winter shelter. Some butterflies overwinter rather than migrate. Rather than clearing your garden in the fall, leave it as is until late spring. Eggs, larvae, and pupae may already be present. In the fall you can add crossed logs, standing dry grasses and leaf litter to provide additional overwintering spaces.
Mineral salts. Creating a mud puddle or a shallow dish filled with sand and water can attract groups of butterflies while providing them with additional nutrients.
Sweet treats. A nectar feeder can also be a great addition to your garden. The recommended solution for nectar is 10 parts water to one part honey. You can also add treats of overripe fruit, such as bananas, pears, plums, apricots, peaches, watermelon, cantaloupe, and grapes.
