Fly Tying: N40 Caddis

I am not really sure why, but there are a few things I like about this fly. Gold beads work. That’s been proven over the last 30 years on about a billion patterns, so nothing original there, but I do think that makes it work.

The fly uses MFC Wonderwrap, which I have to argue is one of the best caddis body patterns you can use.

I like the duck neck feathers as a collar because the feathers are short and therefore you get the soft marabou bottom of the feather as well as the partridge like mottled top of the feather in two wraps, which keeps the fly sparse. Then of course Ice Dub (we literally carry every color at the shop) which is also not original but the stuff works. The fly also sports a small chartreuse butt section on this fly to emulate the color of a shucked caddis, and no, I’m not dumb, I do realize by the time the caddis is to this stage in its life-cycle that the insect is no longer chartreuse in color.

I also realize that fish can’t see color that well under water (supposedly- but who knows really). Since the fly works, I’m going to go ahead and just believe that possibly the fish key in on that color because of the abundance of it in the water but the reality is, it really doesn’t matter why they eat it- as long as they eat it.

If you’re not a tier we will have the N40 caddis in the bins of the Great Falls fly shop this spring already tied up, so come get ya some.

I fish, ski, and climb. I ride my bike to work so that I don't get too fat in my office job. I'm an eater of pizza and have chosen red as my favorite color. I know under 100 Spanish words which I piece together and get laughed at on trips south. Steelhead fishing is life. My wife and my son Jackson are more important than life. I don't like Chubby Chernobyl's. I have the best friends and family on earth, and they are all anglers. I've been educated in New Zealand and Argentina by people much more creative than myself, and it was not from a text book. I'm inspired by creative people. I work with friends, and they motivate me to be better. I like to read. I like to fish, climb, and ski (in that order). I enjoy bringing people in the Northwest US the very best products and values for what we need to live, work, and play; I'm serious, I really obsess about it. Cheers :)
