Thanks for visiting Delaware butterflies. This small Atlantic Coast state ranks on the lower end of state butterfly diversity with 70 species of butterflies and 50 of skippers.

What Delaware lacks in butterfly species they more than double that by their butterfly enthusiasm. Two exhibits show visitors the wonders of Delaware butterflies. The first, the butterfly house at the Ashland Nature Center hosts about fifteen species of native butterflies and is open to the public from June through September, the peak of butterfly season. It’s located a short distance west of Wilmington, and a few miles from the Pennsylvania border. Visitors also have the opportunity to see other attractions such as a hummingbird exhibit.

Not to be outdone, The Botanical Garden at the University of Delaware have hosted a native butterfly garden and trail for close to twenty five years. It’s located in Newark, DE, close to both the Maryland and Pennsylvania borders.

Residents interested in building their own Delaware butterfly garden can get great tips on the larval host plants and nectar plants for their favorite butterfly species.

The top picture shows an Eastern Tiger Swallowtail, the official Delaware state butterfly. Some people might be unfamiliar with the fact that a handful of trees are host plants for the Eastern Tiger Swallowtail. Residents can choose popular trees and shrubs such as lilac, willow, birch, ash, wild cherry and tulip poplars to insure they make a home for the Eastern Tiger Swallowtail from year to year.

Brushfoot butterflies, another group of large showy butterflies are also popular butterfly garden guests.

Butterfly identification usually begins with color. So, the butterfly section is split into nine different categories based on wing color and/or the butterfly family to help all visitors and members easily categorize and document their butterfly pictures.
