This fly isn’t good looking but it’s been productive. This is just one of a ton of different color combos. It’s always fun whipping one of these together in an odd color and seeing if it’ll work. This one’s tied on a #10 with about 4 wraps of .020 lead wire. The body is simi-seal dubbing, with a marabou tail. It’s simple but effective!
That is a nice fly. Did you use a dubbing loop for the body?

Leeches like tis patterns are hands down, my most productive pattern, often tied in all black. Easy to tie, durable and very productive, what more can you ask for?
Jim Smith
Great pattern. I like the dubbed body.
Alberto, yes sir I did. Split thread or dubbing rope works great too though.
Jim, I don’t know of anything else! It’s a great fly for sure.
NJTroutbum, being that the body is all dubbing it makes for a quick fly to tie.
If you like that fly…strongly suggest you consider buying “Flies of the Southwest” by Mike Yeager. Pretty good little book for only a dollar on amazon.com. Check out the KP Buggers and such. Interesting it is much cheaper on amazon than on ebay!
Yes I know Mike. But we have zero contact. The post is for to help FAOL’ers…not to benefit the author.
Very good! Great fly! That was also my best trout producer this Fall.
Hi,
Nice tie! May I ask for the ingredients? I can figure some out, but the tail, buck tail? And how much dubbing?
Thanks,
Mike
Very nice.
Fished where? Moving water? Still water?
Fished how?
Mike, The tail is marabou. And I put enough dubbing to make a fair sized body on the fly, I’d say a couple pinches of dubbing? It really just depends on how full you want the fly to look. When you put it in the dubbing loop it’ll really flare out.
Steven, I fish mine in moving water, and I either dead drift it or while it’s drifting down I pump the fly.

Learn to tie the simi seal leech from the guy who invented it.
To be fair, Rohmer did not invent this pattern, just modified an existing one by changing the material. The mohair/angora goat leech is a very old pattern. It can be tied with any long fiber dubbing, whether natural or synthetic, or with mohair, which is angora goat yarn. I personally prefer STS Trilobal for these because it is not as flashy as Semi-Seal, but have some of those as well, for murkier conditions.
Thanks Liljoe. Now I have a use for lots of dubbing on a fly! I teach classes and the mantra is “Take a pinch and use half”. I may have to adjust to “Take a pinch and add half”!
Mike
Liljoe, is Warren rubbing off on you?

Ed, now what would make you say that? 
Right off the vise it looks like it’s already been chewed by some fish, which is a good thing; real nice fly.
