Winter Fireflies Emerging
After pupating in a rotting log, adult Winter Fireflies emerge in late summer and are often seen on the trunks of trees. When the temperature starts to drop, they crawl under tree bark for the winter. They stay there until late winter/early spring when they reappear. Considered a pest by some sugar makers, they’ve been said to “circle around sap flows on maples like cattle around a trough.” Although the adults do not possess the bioluminescence of the firefly species we see in the summer, the larval and pupal stages of Winter Fireflies do produce their own light.
