Grants Pass, OR Posts: 305 | Perhaps you meant Brachycercus - or whatever it is today? | |

Northern CA & ID Posts: 2604 | Hi Creno, Don't think so, at least about Brachycercus... Slim Baetid bodies, two tails, spurred hindwings. But I'm operating from memory about the wings since my samples are too rumpled in the alchohol with the magnification I have available. Even so, I'm probably still wrong about Centroptilum since I believe the few species documented of even minor importance have been shifted to other genera in the Baetidae family. I didn't know where else to put my experience with this fly. Best regards, Kurt | |

Northern CA & ID Posts: 2604 | BTW, isn't Brachycercus supposed to be a warm water only mayfly as well? | |

Site Editor Royse City, TXPosts: 1350 | Kurt- Should probably have enough sense to avoid getting involved in this discussion, but unfortunately, I seem not to. Jason probably misspoke himself, and actually meant to say Brachycercus (the mayfly) rather than Brachycentrus (the caddisfly). Those two names are so similar, that I have made the same mistake on multiple occasions. The two other names, which I have a tendency to confuse, are Rhithrogena (the mayfly) and Rhyacophila (the caddisfly). Not sure why; perhaps just a short in my wiring. Anyway, you really lost me when you said: Don't think so, at least about Brachycercus... Slim Baetid bodies, two tails, spurred hindwings. Aren't you actually describing Centroptilum rather than Brachycercus? Just asking :-) | |

Northern CA & ID Posts: 2604 | Hi Roger,Jason probably misspoke himself, and actually meant to say Brachycercus (the mayfly) rather than Brachycentrus (the caddisfly). I noticed the mistake too. Just figured it was a typo because Jason wasn't making reference to a caddisfly. I do it all the time myself. Anyway, you really lost me when you said: Yes. I was describing my specimen in response to Creno's question. My original post isn't showing up in this thread for some reason, but in it I made reference to a mayfly hatch on Fall River. Prior to the recent revisions I would have called it a member of Centroptilum genus which is why I posted it there. Haven't got a clue what to call it now, other than a Baetid. Following that post, Creno asked whether I meant to call it a species of Brachycercus. Sorry for the confusion. I have no idea why the thread is split up. Regards, Kurt | |

Northern CA & ID Posts: 2604 | Hi Roger- There I go again! I failed to tell you where the first post was! It's under the Centroptilum genus hatch page. (Edit by Jason: Here's a link to it.) After reading my first post, you'll be able to connect the dots in this thread. In that first post I neglected to fully describe the fly, which prompted Creno's question. Kurt | |

Site Editor Kennewick, WashingtonPosts: 115 | Creno, The specimens of Centroptilum conturbatum shown in these photos were collected by me at the outlet from Bowman Lake, Glacier National Park, Montana. Definitely not a warm water habitat with plenty of trout.This genus has also been collected from several lakes near Many Glaciers in Glacier Park and several cold streams, and Flathead Lake. It does not seem to be abundant in these areas and I have not collected any adults. Brachycercus is definitely a warm water mayfly. I have collected only in the lower Yellowstone river in eastern Montana. A long way from any trout. Brachycentrus is of course a caddisfly with two species present in western streams and the adult hatch is often called the "Mother's Day Hatch", of great interest to trout. Bob | |

Site Editor "Bear Swamp," PAPosts: 1681 | Ha! :) Rather than attempt to deconstruct this rather confusing thread, I'd suggest changing the 1st para. of the Centroptilum text to read this way: "These very small mayflies usually inhabit slow or still water and might be of local importance to fly fishers in some cold lakes, calmer sections of some spring creeks, or cold brooks in beaver pond meadows." (The last location is based on comments in McCafferty and Waltz, 1990) Perhaps the Nymph Biology comments could be changed to this: "Because the nymphs are usually found in slow or still water, their importance to fly fishers is limited to areas where significant populations share this habitat with trout." Can anyone confirm that the description of their emergence habits is accurate? Kurt made this comment in the related thread: Though the generic name has not been done away with, most species of possible importance to fishermen have been scattered among several genera (at least for now) where this unique wing feature is not shared, thus making stream side identification beyond the familial impossible. It seems that most of the relatively recent revision/movement of the bugs in question has occurred between Centroptilum and Procloeon. I'm not sure if current concepts of these genera are still bouncing back and forth, but as I understand it, both now include adults that may or may not have hindwings. Some species of possible importance to (some) anglers are still (or currently) in Centroptilum. These include C. album, C. almance, and perhaps others. PS--After composing this little message, I noticed that Kurt had revised the Centroptilum info. The problem of Brachycentrus/Brachycercus confusion (at least) has been solved. :) | |

Northern CA & ID Posts: 2604 | Hi Lloyd, Yeah this thread is confusing. What happened I think is that Dave in attempting to respond to my initial post accidentally started a new thread with it. Additional confusion was caused by the the "new" threads title which referred to Jason's typo and was unrelated to the text of either post. My first post can be found at the bottom of the Centroptilum genus hatch page which if incorporated whould make the thread slightly less confusing.:) "These very small mayflies usually inhabit slow or still water and might be of local importance to fly fishers in some cold lakes, calmer sections of some spring creeks, or cold brooks in beaver pond meadows." Almost added similar language but thought the better of it as there just isn't enough known yet to limit it that specifically. Fall river for example, though often described as a big "spring creek" is really in a different category. Ditto some of the small streams Bob may be talking about. Regards, Kurt P.S. After posting this, I noticed Jason provided a link in the 3rd post above. Thanks Jason. | |

Northern CA & ID Posts: 2604 | In follow up -It seems that most of the relatively recent revision/movement of the bugs in question has occurred between Centroptilum and Procloeon. I'm not sure if current concepts of these genera are still bouncing back and forth, but as I understand it, both now include adults that may or may not have hindwings. Some species of possible importance to (some) anglers are still (or currently) in Centroptilum. These include C. album, C. almance, and perhaps others This is my understanding as well, though I'm not sure which species will end up being important. I would have been more accurate to have stated that the various hindwing morphologies of baetids were scattered and intermingled within the various genera. However, my central point that "determining the genus of a newly encountered baetid with any certainty while fishing has been rendered impossible" remains valid. That is unless one has the habit of packing a microsope in their vest and towing an entomological library around. Of course there are perhaps a few anglers with eagle eyes and encyclopedic brains that could challenge this notion.:) Regards, Kurt | |

Novi, MI Posts: 2608 | That is unless one has the habit of packing a microsope in their vest and towing an entomological library around. No! Kurt, you and Mr G have just convinced me to simplify, simplify. simplify! I'm not packing in a damn microscope! Spence | |

Northern CA & ID Posts: 2604 | Spence - I propose Troutnut have a special hatch page for the family Bastardidae. The info will be simple. They can hatch anywhere, anytime and they can be any size or color. The most popular being little Gray, Tan, or Olive Bastards. A word of caution though... If somebody ever shouts downriver wanting to know what you're using after releasing your 6th fish to their 0, don't respond, "little yellow bastard!", especialy with the wrong tone of voice. You might end up with your hocky jersey jerked over your shoulders.:) | |
