Adult Mayfly: The mayflies that we find when we do a stream monitoring are the nymphs which live in the water feeding on algae and decaying matter. After a period of growth, the nymphs molts into spinners and emerge from the water to mate and the cycle continues. Photo by Keith Roragen.
Thanks to my faithful crew of Averill, Emily, Colette, Maria and hopefully a new member - Tabatha Cutler for running an efficient spring monitoring. We dodged a thunderstorm, but overall conditions were good.
The good news: we found a Ameletid minnow mayfly and salt PPM was 92 - less than 100 is "good" for us. The bad news: our diversity of macroinvertebrate families was down
Notes from our team leader, Frank Sanford:
