I found and interesting fly design and tried to tie it myself. Mylar used in this fly is not tied directly on the hook shank, but it is sort of extension of the hook. The mylar is tied off at the end, wit addition of some glue. Inside the mylar there is a glass rattle that slides back and forth. For the main body I used white/two shades of tan/grey EP fibre. The gills are made of red craft fur. Finished with 10mm eyes and UV resin.
