I said it before and I will say it again, why all the interest in Gray Drakes? I notice there is consistent and more than moderate interest in ‘grey’ ‘gray’ drakes. I have researched, to the extent of my emtomological researching capabilities, Ephemeroptera (Order), Siphlonuridae (Family), Siphlonurus (Genus), Occidentalis (Species) (That’s all the fancy bug talk from me, thanks to TroutNut) and I noticed that Trout Nut and Rick Haefle don’t rate it very high on the significance chart of mayflies for trout. They either crawl out from the edges of quiet waters or emerge up to protruding rocks and reeds. There is no definitive agreement on how they ‘hatch’. There seems to be agreement that at some point in the day (they can’t agree on when) there is a Spinner fall that could be of interest to flyfishers. Seems pretty vague to me to warrant all the fuss. Write to me and tell me why the interest.
