This particular individual was found floating in a bucket of sugar maple sap on the GNC property. This particular sugar maple is very old and has lots of places for insects to hide under the bark. It is known that this species likes to overwinter under the bark of trees and feed on maple sap. It was placed back on the trunk of the tree so it could be photographed.

Lampyridae is a family of insects in the beetle order Coleoptera. They are winged beetles, and commonly called fireflies or lightning bugs for their conspicuous crepuscular use of bioluminescence to attract mates or prey. Fireflies produce a "cold light", with no infrared or ultraviolet frequencies. This chemically produced light from the lower abdomen may be yellow, green, or pale red, with wavelengths from 510 to 670 nanometers.
