LEPIDOPTERA

Research has identified Lepidoptera (butterfly and moth) larvae (caterpillars) as critical links in the food chain and act as good indicators for ecological resilience in a landscape.

The larvae eat a plant’s leaves, essentially converting sunlight into protein for hungry birds.

The adult butterflies and moths then pollinate plants, along with other insects such as wasps, flies, and beetles.

Following is a list of important keystone plants native to Virginia. The numbers indicate the quantity of lepidoptera species supported by each plant.
