The Massachusetts Butterfly Club sponsors state-wide butterfly activities to promote education, conservation, interpretation, and fun! We invite people of all ages and levels of expertise to attend our meetings, programs, field trips, and butterfly counts and to become members of our club.


UPDATE - An update has been made to the 2015 Schedule. The "July counts" has a change to add the Blackstone Corridor (Upton) count on July 11th.

There is a new look to the left menu on our website. We set up three new groups and have taken some of the old links and made them sub menus of those groups. Check it out. Comments can be sent to the webmaster.

Also, we added a new section to the website to display a list of books, guides and other media types that were either written by a club member or are used widely by club members. The new section is called "Books and Guides" and can be accessed by a link under the "References" group on the left menu.

The April 25th Sunday Telegram had a "Sit-down" interview with Naturalist Dave Small. To read the article, click here or you can also find the link on the "In The News" section under the "Club Information" group in the left menu.
