Mangler – Sally by Umpqua
Taylor designed this fly when he was in high school. This fly was originally designed to imitate the Nemoura and Capnia (Little black winter stone as many people refer to it) due to the lack of winter/spring stone fly patterns available.
Taylor kept this pattern under his hat for almost 2 decades until he started having his staff tie them for the shop guides and customers.
This fly quickly blew up as one of our most popular flies sold at the Missoulian Angler fly shop. Now he is excited to have the help of Umpqua to produce this pattern.
The Yellow Sally version is the same style as its predecessor, and just as deadly.

Austin Gill –
I’ve used the Yellow Sally for several seasons now and it’s consistently catching fish in cold water streams. The pattern matches the natural insects well and is easy to tie. It’s become a go-to fly for my winter fishing trips.
Steven Hart –
This fly performs exactly as described. The design is authentic and the color stands out in the water. I noticed a significant increase in strikes after switching to this pattern.
Justin Martin –
Great imitation of the winter stone insects. It works well in clear streams. A bit more expensive than other flies, but the performance justifies the price.
Carol Alsop –
I tied this pattern myself and found it to be very durable. It holds up well in the water and doesn’t break easily. The original design is still effective after 20 years of use.
Tim MacLeod –
Fished it during a cold spring trip and caught several trout. The fly looks natural and moves well in the current. Would recommend to anyone targeting winter stone insects.
