The sixth year of Firefly Watch has officially begun! The first fireflies of the year were spotted in South Carolina on March 12. You can download the First and Last Sightings Chart to estimate when you might expect to see them in your neighborhood.
Here in the Northeast, we won't see any fireflies for about six more weeks, at least not the summer variety. Even so, we still have firefly activity here. In late March I noticed the winter fireflies, Ellychnia corrusca, beginning to emerge from hibernation and moving about on their hibernating trees. To learn more about winter fireflies, read our February featured research paper , "Notes on the Life History and Mating Behavior of Ellychnia corrusca."
Speaking of the winter firefly, remember to report only those fireflies that you see flashing. Our study does not include daytime fireflies like the winter firefly, or larval fireflies. It is very important to report as accurately as possible. If you have any doubts at all about what you are seeing, it is better to report no fireflies.
