A truly superb book about the butterflies of eastern North America is "Butterflies of the East Coast, an Observer's Guide" by Rick Cech & Guy Tudor, 2005. Books and photographs don't come much better.
In a way, of course, butterflies can be almost anywhere,
but places such as this,
Mildred's butterfly garden in Cape May Point, New Jersey,
can be very good for seeing them.

SOME COMMENTARY REGARDING BUTTERFLY IDENTIFICATION:
"Get a guidebook, take a few years, and
you'll still make mistakes. Butterfly identification has an initial, deceptive
Individuals in a species vary naturally, an eyespot slightly larger, a color brighter.
Males and females of a species can be strikingly dissimilar.
So can genetic morphs or forms within a gender.
In a single species, butterflies that live in a range of habitats can vary in appearance and produce different populations or geographical races, each better adapted to its environment.
Species can also produce generations of distinct morphs in the same place at different times of the year.
One Tiger Swallowtail is black. On the same
flower, another Tiger Swallowtail is yellow.
Another species produces red butterflies in the wet season and blue in the dry. A species darkens in response to air pollution.
A species gains an eyespot. A species loses one."
The above commentary taken from the book, "An Obsession with Butterflies", by Sharman Apt Russell (a wonderful read).
REGARDING A STUDY RELEASED IN AUGUST 2012 RELATING CHANGES IN BUTTERFLY POPULATIONS IN MASSACHUSETTS:
The Harvard study, conducted over 2 decades, found that populations of warm-climate-adapted butterfly species grew by as much as a thousand fold, while those of cold-climate-adapted species that have long been native to Massachusetts declined substantially, by as much as 90 per cent.
Data was collected during the 2 decades by the Massachusetts Butterfly Club, an amateur naturalist group that tracks butterfly sightings and numbers.
17 of 21 northern butterfly species in Massachusetts were found to be declining, including the Atlantis Fritillary and the Acadian Hairstreak.
12 southern butterfly species, which were rare or unseen in Massachusetts in the 1980s & 1990s, were found to have increased tremendously, especially in warmer parts of the state. Such species include the Zabulon Skipper and the Giant Swallowtail.
For most of the species in the study, climate change seems to be a stronger cause than habitat change.
