Wisconsin Posts: 663 | Jason, excellent! Now that WI has an extended inland trout season I have been on the hunt for the elusive Great Autumn Brown Sedges (Pycnopsyche), especially the pupae. So far no success. | |

Administrator Bellevue, WAPosts: 2737 | Thanks Dave. I was wondering about that, after looking up the paper with the spur counts after taking the pictures. I thought from the pictures it looked more like 1-2-2, but your comment prompted me to go back and check it under the dissecting microscope. It's 1-3-4, clear as day. I just don't have as good an eye for spurs versus those smaller spikes on the legs in the photos, but the difference was really obvious under the scope. | |

Grants Pass, OR Posts: 305 | Great Dicosmoecus pics Jason. I presume you kept it :-) The globular 9th I think I am seeing and the very dark, contrasting vein coloration are more typical of D. gilvipes. If you kept it take a good look at the spur count. D. atripes is 1-2-2 while D. gilvipes is 1-3-4. From what I can see the meso-tibia in several of the pics have 3 spurs. However, I am fairly sure fish don't count spurs :-) Have fun creno | |
