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.
Closeup insects from Mystery Creek # 249
Female Rhithrogena hageni (Western Black Quill) Mayfly Dun
View 7 PicturesI was surprised by the olive cast on the body of this female Rhithrogena dun, which led me to mistake it for a western green drake (Drunella) in the field. I was pleasantly surprised to get a closer look and find something I hadn't collected yet. Its species ID is based on proximity to male spinner collected on the same trip, as well as physical similarity (size, tergite (Tergite: The top (dorsal) part of a single segment on an insect's abdomen when it consists of a single chitinous plate (sclerite), or an individual sclerite if the segment has more than one.) coloration, dark streaks on the femora (Femur: The main segment of an insect's leg close to the body, in between the tibia and the trochanter.)) to that specimen.
