Fireflies! Summer is Here!

I saw the first fireflies of the season in the backyard as we were relaxing on the deck after dinner. There were quite a lot of them. But as usual, early in the season, they were almost all gone by the time it got completely dark. This is the earliest that they have appeared in the six years that I have been keeping track.
