There is just a crystal flash (in this case black) tail under the foam. Otherwise, you've got it:
1) thread base and flash tail
2) tie down rear foam
3) peacock herl body (kapok for the white one)
4) tie down front foam (I believe there is a middle tie down in the OG pattern to create 3 body segments. I do it sometimes.)
5) flash underwing (matching the tail) and hair wing
6) tie back the head
7) legs, poly sighter, dubbing
Edit: Huh. I just watched a couple videos out of curiosity, and it appears that at some point I added the flash tail and underwing to the original recipe. Must've been in my cups, but I've been doing it that way for years.
