Types of Butterflies in Delaware

About 120 species of butterflies exist in Delaware. Here, butterflies typically breed between June and August, with activities peaking up from mid-July to mid-August. But bad weather or insufficient food resources can change the scenario. Butterflies occur in deciduous woods, near streams, rivers, wooded swamps, and in towns and cities throughout the state.

The Tiger Swallowtail (Pterourus glaucus) is the official state butterfly of Delaware.
