Butterfly Videos

Dick Walton has graciously provided access to a series of short online videos on Skipper butterflies. I think these videos illustrate butterfly behavior, and act as aids to identification, in ways that still photos simply cannot. Enjoy! And thanks to Dick Walton for providing them to us. You can check out more of his material at

Butterfly Flight Dates

Erik Nielsen, our club's former records compiler, has generated a handsome chart of butterfly flight dates based on club members' observation records from 1993-2007. The chart can tell you at a glance which species have been observed in Massachusetts at different times of the year and whether observations are rare or common. Be sure to report your butterfly observations to our new records compiler, Mark Fairbrother, so they can be included in the club's yearly summary and in future versions of the flight dates chart.

Photo Credits

We are in the process of compiling digital butterfly photos from club members and other butterfly photographers. We would like to use only photos taken in and near Massachusetts so they reflect the local forms of these species. Many, many thanks to

Endangered Butterfly Species in Massachusetts

There are currently eight butterfly species listed by the state (or in the process of being listed) as endangered:

Quoting from the Massachusetts List of Endangered, Threatened and Special Concern Species:

"Endangered" (E) species are native species which are in danger of extinction throughout all or part of their range, or which are in danger of extirpation from Massachusetts, as documented by biological research and inventory.

"Threatened" (T) species are native species which are likely to become endangered in the forseeable future, or which are declining or rare as determined by biological research and inventory.

"Special concern" (SC) species are native species which have been documented by biological research or inventory to have suffered a decline that could threaten the species if allowed to continue unchecked, or which occur in such small numbers or with such restricted distribution or specialized habitat requirements that they could easily become threatened within Massachusetts.

If you find these species, please take a photograph, note your location carefully, and use Massachusetts Division of Fisheries & Wildlife Vernal Pool & Rare Species reporting system to report your sighting.
