Firefly Watch Citizen Science Project
Firefly Watch combines an annual summer evening ritual with scientific research. Join a network of volunteers by observing your own backyard, and help scientists map fireflies found in New England and beyond.
Why Watch Fireflies?
Are firefly populations growing or shrinking, and what could lead to changes in their populations? Mass Audubon has teamed up with researchers from Tufts University to track the fate of these amazing insects.
With your help, we hope to learn about the geographic distribution of fireflies and what environmental factors impact their abundance.
How to Participate
It's easy to participate in Firefly Watch. All you need to do is spend 10 minutes once a week during firefly season observing fireflies in one location (your backyard or in a nearby field). All firefly sightings—or lack thereof—are valuable. Find out how to participate >
If you have participated through Museum of Science (MOS), you will need to create a new account with Mass Audubon. Any data you’ve entered on the MOS site this year is not displayed on our sighting map but will be retained.
