The green fly with hackle is a California neil or a coho bugger. I think Frank Dalziel had a part in the bugger name, never heard the California name origin.
I'll say again, i'm no expert, but this is what i used to tie these flies- if anyone knows any better ways i'm all ears. Here is the recipe:
Coho bugger
Hook - you could probably go anywhere from a 6 to a 10 or 12. I used a longer shank for the bead head fly. Both hooks are saltwater hooks.
Thread - I used chartreuse waxed 6/0
Tail - chartreuse bucktail with chartreuse krystal flash over top. You could use polar bear as well. When i buy bucktail, i always take it out the pack and get one with the straighest hairs- i avoid buying the wavy ones.
Body - diamond braid dyed chartreuse wrapped around the shank
Hackle - grizzly
Rib- fine red, green, silver or gold wire, counter wind hackle
I put a tungsten bead on one of them for a little depth.
I don't have a name for the blue and olive ones. Baitfish immitation.
The body you asked about is silver diamond braid wrapped around the shank. I tied in a linear piece of lead on some of them. I find wrapping a lot of the shank makes it go too deep for the beach and wrapping only part of the shank causes a bulge, so i measure off a piece of say 0.20 lead and bind it down along the shank. Here is the recipe:
Hook - tiemco 9294 (i think). Its about 3xl long, smaller ones are size 8, larger ones are 4.
Thread - 6/0 white.
Body - white thread on some, silver diamond braid on others
throat - red hackle barbs bunched together. You could use red calf's tail.
wing - most have white bucktail, then blue or olive over top. One has some peacock hearl on top of that. As I said before, i always take bucktail out the pack and get one with the straighest hairs. They don't flare as much when tied in. I have never used polar bear, to be honest i'm a little uneasy using an endangered species for a fly. Seems like selective conservation to C & R fish on a barbless fly tied with an endangered animal. Not taking the moral high-ground, don't mind if others make their own decision, i just never have used it.
head- i build up a head with thread to match the body diameter and whip finish. Then i start 6/0 red to add gills and whip finish it.
eyes - pre-made stick on eyes. I press them on and hold it tight for a while to get them to curve to the shape of the head.
You can finish with an epoxy head. I used two coats of super glue on these.
I think thats about it! Good luck with that!
Cheers,
