Here is another mayfly pattern, that I tie and use regularly. Its body is made of foam, which makes it almost unsinkable… and it catches fish! I caught some of my biggest dryfly browns on this pattern.
Here is what you need:
- Hook Partridge Klinkhamer #12
- Thread: Unithread 6/0 brown
- Body: foam white in 2mm (better is 1mm!), yellow and brown markers
- Tail: spinner tails natural grizzly
- Wing: deerhair
- Parachute hackle: Rooster saddle olive
- Thorax: SLF Squirrel Spikey Dubbing brown
First you need to tie a foam body, as has been used in a great variety of flies, from grasshoppers, to longlegs and also for mayflies. See for example here click. I use white foam, as our mayflies here are rather light in color. In other regions I have seen flies that rather yellow or olive, for imitations of these you can use foam in the respective colors.
