Pollinator gardens not only can provide nectar for butterflies and other insects, but also will help to support the caterpillar stage of butterflies and moths if you add their native host plants.
Native host plants are the plants where butterflies and moths lay their eggs. They’re important because those plants are what a new caterpillar will start to eat after it has hatched.

Butterflies and Moths of North America (BAMONA) The BAMONA project aims to serve as a one-stop database of butterfly and moth data that scientists can use to form or to address research questions. While it is a collaborative effort between individuals with varying levels of knowledge and experience with Lepidoptera, contributors share a common goal of assembling high quality data on butterfly and moth distribution.
