GR8LAKESFLYER, I had no idea the blue charm is a dee pattern. I tie those for my local trout too. Actually it has been my most productive fly this past year. I assumed all dee flys had V-shaped slip wings... I don't really study flies or their history in depth, if I see one on the interweb that looks pretty, I try to tie one and fish it!
The term "Dee fly" gets used rather often and quick ... and most often, misguided and directed
Dee flies fall into different categories, mixed wings, married wings, strip wings, "V" wings or "Delta" as some call them. But they are all feather wings.
Colin Innes has a wonderful website called Feathers, Flies and Phantoms
, it is filled with real Dee patterns, history and examples ... some other cool stuff too. You will be shocked to see some patterns that are listed as "Dee" flies
He has written a book called "The Lost Flies of Balmoral", which is a fabulous read and I highly recommend it for all Dee fly wannabee tiers. It really gets into the history of the originators of patterns that we only typically know their names. Colin has researched these fore-fathers of the patterns and gets right into their lives ... cool stuff. Some patterns in the book I have never heard of, so many were a surprise. Check it out.
Yes, the Blue Charm is one of those flies that is like ringing the dinner bell on the river, no matter the quarry
I found other patterns on Colins' website and in his book that have much the same "charm". I'll give you one ... The Clunie (Cluny). You will have to go to Colins' site for the recipe though
