▸SECTION 1
Chapter 2 of the General Laws is hereby amended by inserting after section 63 the
following section: -
▸SECTION 64
The Black Swallowtail, scientifically known as Papilio polyxenes, is hereby designated the
official butterfly of the Commonwealth of Massachusetts. Adorned with striking black wings accented by
yellow spots and blue hindwings, the Black Swallowtail plays a vital role in our ecosystem as a pollinator.
It symbolizes the Commonwealth's commitment to environmental stewardship.
This butterfly is a symbol of natural beauty and a reminder of Massachusetts' rich agricultural history.
Historically common in farm fields, the Black Swallowtail has adapted to various habitats, including the
many meadows, gardens, and urban areas of Massachusetts. Its selection reflects Massachusetts'
dedication to celebrating and protecting its diverse natural environment.
This designation is made in honor of William P. Callahan III, alifelong resident of Massachusetts who
passed away from cancer in August of 2021. Billy could be found chasing and photographing butterflies
throughout New England on nearly every sunny day (and even some mildly rainy ones) for the last
decade before his death. An active member of the Massachusetts Butterfly Club, he took a bucket list trip
to Costa Rica with his daughter Cara in June of 2021 to observe the wide variety of species found there. A
bench is named in his honor at the National Butterfly Center in Mission, Texas. His final excursion was a
walk-through of the Northampton, MA Community Garden, one of his favorite local spots.
