A crayfish chews on a Hexagenia limbata nymph shortly after a small Hex emergence. I didn't catch any fish, but playing around with my flashlight and camera in the rocks proved productive.

I have read in many places that the Hex nymph is a mud dweller. What does this mean? Does this mean they immediately change from egg to nymph and then burrow into the mud until emergence or do they simply burrow in the mud to find food and spend some time in the open water between meals? I have heard comments from fisherman that indicate they know the hatch has been happening when they see small holes in the muddy banks of the river. This is abit confusing to me. Could someone please clarify.

ReplyAn odd observation of Hexagenia 2 Replies »I'm reading up on mayfly rearing in preparation for this season, including Needham's 1935 classic "The Biology of Mayflies." (Very rare and somewhat outdated, but the most comprehensive book ever written about mayflies by far.) I found this quote strangely casual:
I've got to wonder who first thought to try that.
ReplyHex is next!The eggs of Hexagenia may be obdatined from a subimago by placing her on the surface of a beaker of water and snipping off her head. She will pour them all out immediately from both oviducts -- in the case of H. occulta some 5000 of them (Needham 1908, p. 260).

Well the Hex is right on the cusp of happening...
I have heard rumors of some being spotted on the Nam...about right. I usually set me clock by the Solstice but this season is about ten days to two weeks ahead.
I expect them to show on the Brule anytime too. The next warming trend should usher in some of the big fellows and that will mean no sleep for a couple of weeks for this cat.
I need to sit down and get to tying. I had great success last year with a very 'soft' spinner pattern I dubbed Baby Doll Hex. It was floppy by hex spinner standards and best the pants off the stiff Lucca style patterns that look good int he fly bin but are not for me on the end of my leader when the rubber hits the road!
I also need to reread Galloup's "Cripples and Spinners" - a wealth of info on this aspect of the sport. Great for inspiring tying ideas...
Anyone confirm the reports?
