2008 Mercer Butterfly Count Results
Frank Bader

Twenty one Field Observers took part in the Mercer Butterfly Count on July 13, sponsored by the Washington Crossing Audubon Society. Many thanks for their efforts on this hot day.

We totaled 39 species and 5561 individuals. Four species were new to the count; Variegated Frittilary, Fiery Skipper, Zabulon Skipper, and Broad Winged Skipper. Eastern Comma was missed for the first time.

The totals are all contained in the spreadsheet on our website, www.washingtoncrossingaudubon.org. The Count's 5561 individuals is the record in its six year history. Historic highs were reached for Spicebush Swallowtail, Eastern Tailed Blue, Juniper Hairstreak, Pearl Crescent and Common Buckeye. The number for Pearl Crescent (2826) is especially notable. It tops the totals for all species in years 2005-2007. In 2003 the Mercer Count had the nation's high with 689!
