No doubt the people of Massachusetts love their Massachusetts butterflies as much as they love their Boston Red Sox. According to the Massachusetts Audubon:
From 1986 to 1990, hundreds of volunteer butterfly enthusiasts spent thousands of hours in the field in an effort to record the distribution of Massachusetts butterflies—the first systematic statewide butterfly atlas to be undertaken in North America.
Thirty years later and the enthusiasm for butterflies continues.
A 2013 study published in the journal Nature concluded
From 1992 to 2010, 19,779 butterfly surveys were made by amateur naturalists in Massachusetts, a geographically small state located at the convergence of northern and southern bioclimatic zones in eastern North America. From these data, we estimated population trends for nearly all butterfly species (100 of 116 species present)..Population trajectories indicate increases of many species near their northern range limits and declines in nearly all species (17 of 21) near their southern range limits. Certain life-history traits, especially overwintering stage, were strongly associated with declines. Our results suggest that a major, climate-induced shift of North American butterflies, characterized by northward expansions of warm-adapted and retreat of cold-adapted species, is underway.
One must also conclude that the list of Massachusetts butterflies presented here, along with pictures of representative species, will no doubt change over time.
Butterflies: Whites and Yellows
Comparatively speaking, Massachusetts has a lower than average number of butterfly species in the family Pieridae. They are rather evenly split between the butterflies with white wings and yellow wings. The picture shows a Little Yellow butterfly. Here’s a list of the rest of the white butterflies and yellow butterflies documented in the state.
West Virginia White
Blues, Hairtreaks and Coppers
Many of Massachusetts butterflies have a nation wide distribution. The Azures are an example in the gossamar wing family. Azures can be identified by unmarked, light-blue upperwings. Females have wide dark edges around the forewings. From a side view picture, the underwings show a white background, coupled with a variable number of small black spots Basically there are spring and summer varieties, depending on when they appear.
The twenty hairstreak butterflies are also common Eastern species. The picture shows a Red-banded Hairstreak.

Brush Footed Butterflies
With monarchs, queens, viceroys and emperors, Massachusetts almost covers the royalty butterflies. Add in the admirals and now the royalty have nominal protection. All of these species are common to residential areas and gardens around the state. The White Admiral in the picture is easily identified by the large white stripes along the top of the wings.
Great Spangled Fritillary
arthemis White Admiral
Astyanax’ Red-spotted Purple
Massachusetts Butterflies: Swallowtails
The Spicebush Swallowtail is one of four native butterfly species with dark wings. The picture shows that the top of the wings are primarily dark wit a line of sight spots running down the sides. The abdomen also has light spots on it.
- Pipevine Swallowtail
- Zebra Swallowtail
- Black Swallowtail
- Canadian Tiger Swallowtail
- Eastern Tiger Swallowtail
- Spicebush Swallowtail
- Giant Swallowtail
Butterfly identification usually begins with color. So, the butterfly section is split into nine different categories based on wing color and/or the butterfly family to help all visitors and members easily categorize and document their butterfly pictures.
