Eastern Tiger Swallowtail

On Sunday, Erika and I were pleased to see this Eastern Tiger Swallowtail in northwestern Minneapolis. This butterfly is common across most of the eastern United States. The Washington Post, however, warns that many butterfly populations are falling in our country. Causes for this decline include habitat destruction and widespread use of pesticides and herbicides. Some of my fellow bloggers have noticed a decline in butterfly populations here in Minnesota, although these local observations are antidotal, not backed up by scientific sampling.
