Just asking a question. Unfortunately my camera cannot focus close enough to be useful.
Here are some pictures (copied from the Fly Anglers On-line site, "Lakes and Stillwaters" feature). The first shows a Blond Stayner,
and here's what the author named as the Stayner Ducktail. They are both Stayner's, just color variations of the same pattern. The Blond variation uses a variegated (or mixed) yellow/dark olive chenille with a wood duck dyed mallard feather wing and the original used only dark olive chenille with an undyed mallard feather wing (per this article). Also, there can be many other color variations just by modifying the color/color mix of the chenille and wing. I do know that color variation can be apparent due to the camera and the lighting used when the picture is taken. That was why I asked, that's all.
To see the original article with the pictures - Fly Anglers OnLine, Your Complete Internet Flyfishing Resource. and just put "Stayner" in the search field.
