It takes more than nectar to entice butterflies to take up residence in your garden. While nectar-rich flowers attract passersby to stop and feed, host plants send an invitation to stay a while. Larval host plants are the secret to successful butterfly gardening; they are plants required by a caterpillar for growth and development.

By planting host plants in your garden, you offer a promise of food for the next generation and will attract more butterflies than you thought possible.

Drawing a Crowd with Host Plants

Female butterflies are lured to host plants by a combination of chemical cues released from the plant. Once they locate a host, they begin laying eggs. Males are also attracted to host plants, where they can surely find females for mating.

All this business of searching out mates and host plants is tiring. The adult butterflies will need energy to keep busy. Providing a balance of nectar-rich flowers to fuel butterflies and host plants to nurture young ensures a garden bustling with activity.

But which plants are best? Different species of butterfly rely on different host plants to rear their young and vary in their preferences for nectar sources, so each species has a unique set of ideal plants. Gardeners can take several approaches to designing a butterfly garden. You might focus on a few desirable butterfly species you wish to attract and select host and nectar plants accordingly.

Another option is to go local. Plants native to your region host butterflies native to your region. Try planting a variety of your favorite native plants and enjoy the surprise of discovering which butterflies show up.

Not all butterflies gather energy from feeding on nectar. Some species find nourishment in rotting fruit, dung, and even carrion. While you’re not likely to put a steaming pile of manure or rotting carcass in the yard, you may try offering a fruit-feeding station. Simply place over-ripe fruits on a flat rock or wooden platform and enjoy the feeding frenzy.

Fruit-feeding butterflies include mourning cloak (Nymphalis antiopa), monarch (Danaus plexippus), red-spotted purple (Basilarchia astyanax) and question mark (Polygonia interragationis).

With a mixture of larval host plants, nectar resources and alternative foods like fruit, you are sure to welcome a diversity of winged life into the garden. Add a shallow dish of water and a sheltered place to escape the wind to complete your butterfly oasis.
