After counting fireflies for the MOS Firefly Watch (https://legacy.mos.org/fireflywatch/), I ran back in to get my camera and tripod. This is a 6 second exposure. I think I captured the same firefly doing a quick four-flash twice.
Last night, A. and I went into the backyard to watch fireflies in our backyard. Instead of the usual "sounds of silence". The light show was accompanied by the sounds of fireworks shows in nearby towns.
