When Lisa Daley-Bromberg sent us this photo she took in Uxbridge, Massachusetts asking for an identification, we got very excited.
You see, it’s a pipevine swallowtail, an essentially tropical species, that is very uncommon in Massachusetts.
In fact, there were only 11 records for the state during the 5 years of the Butterfly Atlas Project (1986-1990). But, like many other southern species, it is appearing more frequently in our area due, most likely, to the changing climate.
