Butterfly Host Versus Nectar Plants

Since we’re talking butterflies, there are two terms you need to know, “Host Plant,” which is the plant on which the eggs are laid and the caterpillars feed and “Nectar Plant,” which are the primary plants they feed on.

Here are a few butterflies that you may find in your garden. If you are interested in the host and nectar plants for a specific butterfly, go to the Butterfly page.

This is what you need to take away from this. If we want to keep butterflies around us, we need to decide which ones we want and plant what they need. You may not always get them the first season or the second but eventually they will make it to your yard.
