Results of Delaware Nature Society/NABA annual Northern Delaware butterfly count

Here are the results of the annual northern Delaware butterfly census conducted by members of the Delaware Nature Society (and me) for NABA -- The North American Butterfly Association -- this past Saturday.

We counted 632 individual butterflies from 39 species.

Highlights: All five species of Swallowtail, including one Zebra and one Pipevine, both comparatively rare in northern Delaware (Although Elk Neck State Park in Cecil County, Maryland, is one of the epicenters for Zebras in eastern North America!) If only we could have seen a Giant Swallowtail...

Unfortunately, none of the southern Sulphurs which occasionally make it up here, and none of the more spectacular Hairstreaks.

Here's the list:

Pipevine Swallowtail (1)
Zebra Swallowtail (1)
Black Swallowtail (9)
Eastern Tiger Swallowtail (71)
