The Spring meeting of the Massachusetts Butterfly Club will be held on Saturday, May 9, 2020 at 5:30pm at the Broad Meadow Brook Massachusetts Audubon Sanctuary at 414 Massasoit Road in Worcester.

Our fantastic potluck supper will start at 5:30pm followed by the following presentation:

Steven Fuller, Ph. D., the Science Delivery Specialist of the US Fish & Wildlife Service based in New Hampshire will speak on identifying and planning for the restoration of species determined to be under threatened conditions, including the Frosted Elfin and Karner Blue. Following Dr. Fuller’s talk several Club members will present their photos and knowledge of the Frosted Elfin in Massachusetts.

Following the main program members may show up to 20 of their photos of butterflies as we have done in the past. If you wish to show photos, please let Steve Moore know at

If you have friends who might be interested in this program, feel free to invite them to our meeting which is open to the public.

Butterfly seekers are needed for the 2019 Hessel's Hairstreak Search Project, a joint venture between The Natural Heritage & Endangered Species Program (NHESP) of the Massachusetts Division of Fisheries & Wildlife and the Massachusetts Butterfly Club (MBC). This is a volunteer project and you can commit as much time as you can to it. Even a ½ hour hike at a site would be really helpful. The time frame is from mid-May to the end of June.

Please email Danielle Desmarais at to be added to the email list for all the communication and documents that explain the search in detail.
