Posts: 560 | Darn proper word had me confused as to what they were talking about! I learn the bugs, as they apply to my fishing, and know a number of the latin propers, but a river I fish on occasion, and it is a great river that is under fished, IMO, in Montana, is the Clark Fork River. My fly shop in St. Regis, MT said that Hecuba was on the water. I thought it was attached to the green drakes, the few rivers that have our Western Green Drake in the Fall. Dug through my books, and it is part of the Western Green Drakes that emerge in the Fall, but also a Western Sulphur?? I'm thinking it is what I would identify as a Pale Evening Dun, the long, two tailed, light bodied bugs we identify as Epeorus Albertae. Could both be on our water in late Summer? I have never heard the wold Hecuba used on our SF of the Snake. There is a Western Green Drake on a trib of the SF, and a few rivers in Yellowstone Park, like Slough Creek, that gets the Fall hatch of Green Drakes. | |

Site Editor Royse City, TXPosts: 1350 | Jere- Timpanoga hecuba is a large Ephemerellid which authors Rick Hafele and Dave Hughes refer to as Great Blue-Winged Red Quill in their excellent book, Western Mayfly Hatches. The nymph is really distinctive shaped. Here is a ventral view of one I collected from the S. Fork of the Snoqualmie River in WA: | |

Northern CA & ID Posts: 2604 | Sayfu - Timpanoga hecuba hecuba (Great Red Quill) is a large ephemerellid that can occasionally produce fishable hatches. It's a scary looking bugger with it's large lateral spines. They look like an E. grandis (Western Green Drake) on steroids. They're big! They are fully as long as grandis but much stouter. The genus currently consists of only two subspecies, the other being hecuba pacifica. My experience with them is on streams draining the eastern slope of the Sierras. They seem to prefer silty areas in cobble bottoms and population densities seem to run counter to E. grandis. The years I've seen them in good numbers is during drought conditions when the spring runoff fails to flush things out well. I believe they tend to be sporadic hatchers which may explain why the nymph populations can often be empressive while there emergences remain sparse. Regards, Kurt | |

Posts: 560 | Darn! Lost my post again. I went back to my Craig Mathews book on Yellowstone hatches, a bible for me out here in Eastern Idaho. Here is what he says on green drakes. They are found emerging from June to Sept. And the reason why is the various species of Green Drakes..all closely related taxonomically, but vary in appearance according to the time of year they emerge. There is Drunella grandis, Drunella doddsi, Drunella coloradensis, and Timpanoga hecuba that emerges in the Fall on the Lamar, Soda Butte, and Slough Creek. All 4 species are present on the Gallatin he said. I had flashbacks from reading this on Green Drakes in his book, and now I hear hecuba referred to as a large mayfly. After seeing your pictures I would say that Craig Mathews was wrong, but I would never tell him that! | |

Northern CA & ID Posts: 2604 | Sayfu -Darn! Lost my post again...Don't you hate that! BTW, Craig Matthews wasn't necessarily wrong. It depends on when he wrote his book. They were all species in the Ephemerella genus not all that long ago. Regardless, it is common practice for authors to group the big western ephemerellids together for practical reasons. Excepting its reddish brown body, T. hecuba duns look very much like Drunella grandis in both shape and size. It is a little puzzling that he included D. coloradensis with this group. It is usually associated with D. flavilinea. The two are very hard to tell apart and go by the common names Western Blue-winged Olive or "Flav" (ugh). Perhaps he did because many call these mid-sized olives the oxymoronic name Small Green Drake? For grins (and future reference), here's a list of the more common western blue-winged olive ephemerellids and their average sizes, starting with the biggest first. There are a few more species that could be included and some Pale Morning Duns can blur the lines in many watersheds. Drunella Grandis sub-species 15mm D. doddsi 13mm D. spinifera 12mm D. coloradensis 11mm D. flavilinea 10mm Caudatella heterocaudatus 8mm Attenella margarita 6mm Taken together, they pretty much have the size ranges covered from #8 to #18. :) Regards, Kurt | |

Posts: 560 | Thanks, you have made me remember that I have read that coloradensis is closely associated with Flavilinia, and flavs as I know them. They can come off well on cloudy mid to late afternoons on the Henry's Fork. And Mathew's book on Yellowstone hatches has been out for some years now. Interesting that you say the body color of hecuba is a reddish brown. I listened to the streamer guy, Kelly Gallop give a hatch presentation for the Madison, and he recommended tying Green Drake patterns in a maroon body color as well as the olive body with yellow segmentation. He said that once the green drakes are on the water for a short time they turn maroon in color. | |

Northern CA & ID Posts: 2604 | Yeah, the drunella genus is notorious for darkening pretty quick and Green Drakes often do change from a bright green to a dull brownish olive (edit: not while still on the water, see commentary below). But maroon? Sounds like hecuba to me. Like assuming that PMD's are a single multi-brooded species that gets progressively smaller in baetid fashion, there is a little confusion about these matters in some angling circles. | |

Northern CA & ID Posts: 2604 | Gonzo - Yes, and I've seen them look almost black as well, but many hours later when they're ready to molt, as in the case of the photo you linked. We're talking about duns after the first seconds of emergence when they are available for munching. Do the eastern Drunella species get this dark before molting? Jere - He said that once the green drakes are on the water for a short time they turn maroon in color. Nope, not in my experience. | |

Posts: 560 | Taxon..We use to live on Mercer Island at the light on Island Crest Way and 40th if the light is still there. I have fished the SF of the Snoqualmie many times fishing the Middle Fork more though in the later years. And an interesting note on Green Drakes, and the SF of the Snoqualmie. Not far from the SF I had some of the finest Green Drake fishing going...below the Ensign Ranch not far below the headwaters of the Yakima. All the big fish in that section of river would be up on them, and there were some very big rainbows in that section. First week of June was the timing. The riparian must have been favorable for them. You don't find them below that upper section I do not believe, and the riparian zone changes below Cle-Elem. | |

Posts: 560 | Months later..and I am finally learning how to use this great sight. I have always been very visual, and this site has really upgraded my bug ID from terrible to poor which is a quantum leap. Hughes, in his new book, refers to timpanoga hecuba as a Green Drake (common name), and saying the two are related, and the same flies can be used for both. | |
