I’ve used this fly during late summer streams in Colorado and it caught several fish. The pattern matches the natural hatch well and it floats naturally in the water.
Lily Ellison –
It’s a solid imitation for when Flavilinea are active. I caught a few trout on it during a dry season run. A bit more delicate than other patterns, but effective.

This fly worked perfectly during a late summer hatch in Utah. The detail and color match the real insect, and it’s easy to tie with standard materials.
