DAYLILY DIVING SWALLOWTAIL BUTTERFLY

Female eastern swallowtail butterfly taking nectar from a daylily in Worcester, Vt

An eastern north america native female eastern tiger swallowtail butterrfly, Papilio glaucus, crawls deep into the flower cone of a daylily to drink nectar at a friend’s garden in Worcester, VT.

How fun to watch a swallowtail butterfly dive into a daylily for a drink of sweet nectar. On the way in its wings became streaked with pollen, which the butterfly then took to and pollinated a neighboring daylily in seeking more nectar.

No daylily is native to North America as thus their value to native pollinators is limited to providing food rather than providing food, ideal egg-laying sites and food for their caterpillars that would support this butterfly species’ entire life cycle. Most native butterlies and moths have just one type of plant that is the host plant for their entire life cycle.

Native plants support not just native butterflies, but also all living things in native ecosystems, including humans, which is just one reason to have a diversity of native plants on your property or property that you manage or care for.

While daylilies have good horticultural value as colorful flowers, native plants have both horticultural and ecological value in the landscape. There are many fine native plant substitutes for non-native plants, and I encourage you to explore the possibilities before investing in non-native plants that could take the place of high-performing native plants.
