Members of the Massachusetts Butterfly Club have been mailed a ballot that includes two items.
The first item is a vote for the officers of MBC.
The second is a vote for approving the revised NABA chapter bylaws. NABA (North American Butterfly Association) is requesting that all chapters sign a new bylaws document. The MBC officers have unanimously voted to accept these bylaws. We are asking the MBC members to vote to approve or disapprove the signing of the bylaws. We need to have this ballot returned by October 1st.

Please join us at the Mass Butterfly Club Fall Potluck Supper Meeting, which will be held on Saturday, October 18th at 5:30pm at the Massachusetts Audubon Society Broad Meadow Brook Conservation Center in Worcester. Please bring a favorite dish to share, and remember that alcoholic beverages are no longer allowed at meetings in Broad Meadow Brook.

In our business meeting, we'll discuss changes in the club's relationship with NABA, and announce results of elections for club officers for the next two years. Rick Cech will be our featured speaker for the evening. Rick will talk about the history of natural history, with special emphasis on the natural history of butterflies, of course! Rick is both a member of the Mass Butterfly Club, and the author of the exceptional observerís guide Butterflies of the East Coast, so the evening promises to be a very interesting one.

      Please save the date! We hope to see you there.

This wonderful resource presents new information on the abundance and distribution of Massachusetts butterflies based directly on Massachusetts Butterfly Club sighting data.

The Caterpillars of Massachusetts 2009 by Sam Jaffe

After a fantastic 2009 season spent seeking out and photographing many of our more spectacular caterpillars, Sam has combined his notes on Massachusetts' caterpillar life histories into a single document. Now, with the help of the Massachusetts Butterfly Club, these notes are available online, as a pdf, with accompanying thumbnail links to Sam's relevant photographs.

These notes should not be mistaken for an exhaustive resource, but the information provided regarding caterpillar location, hostplant, season, and behavior might be especially relevant to all Massachusetts butterfly and moth enthusiasts.
