About "Mystery Creeks": I love small streams, but some of my favorite little trout streams are too small and too fragile to publicize here. If you recognize one of these, you already understand why I'm keeping it a secret. These are the kinds of places that lose a little bit of their charm if you see someone else's week-old footprint, and I don't want to do that to them.

Male Cinygmula par Mayfly SpinnerMale Cinygmula par Mayfly Spinner View 9 PicturesThis spinner came from one of those huge swarms that make one just stop fishing and admire the spectacle. Not bad for a little-known species.

In the same swarm I collected a female and another male.
