This is the Hi-Vis Rusty Spinner complete with egg sac that worked so well, particularly during morning spinner falls. This pattern has several versions, some with a cdc wing and rusty goose biot body, and often it is tied without the egg sac. This one is tied with a zelon wing and dubbed body - I tie it this way because I like the look and using zelon for the wing makes it a quick, durable tie. I don't have any well-chewed versions of this fly because by the last day I had lost all of those I had tied. (Note to self; tie more of these before you go fishing anywhere.)
Sharpen your hooks!
