OSA Nymph
Hook #8 to 18
Bead: Black to Gun metal black
Weight: OPTIONAL LEAD WIRE
Thread: Black
Tail: 6 to 10 Pheasant tail barbs, depending on the size of the fly.
Ribbing: copper wire
Abdomen: Black possum or squirrel dubbing
Thorax: White UV Dubbing
Place bead behind hook eye, and wrap the optional lead wire behind bead.
Tie in Pheasant tail in as tail and leave the long butt section, as this will become the legs.
Tie in the copper wire
Apply dubbing and wrap over the pheasant tail fibres, to about two-thirds up the hook shank.
Rib with copper wire and tie off copper wire.
Lift pheasant tail fibres up and dub thread and under the pheasant tail fibres to bead.
Backward and forward wrapping of the UV dubbing can be done, to attain the right density, covering shape of thorax.
Take pheasant tail batbs over UV dubbed thorax and tie in with 2 or 3 wraps behind the bead.
SPLIT barbs in equal numbers and fold to either side of bead/body.
Tie the barbs in at about 45 degrees to body and whip finish.
Trim the barbs about two-thirds of the over all length of fly.
This fly have caught many trout and yellowfish for me, over the last couple of years.
It is one of my 4 or 5 top goto flies, when I start fishing.
It is a general mayfly to stonefly nymph profile. The black bead and abdomen, gives a very good profile against any background and in any light conditions, with the UV dubbing add a different depth, dimension in the light and in the light spectrum.
I paged thru some old magazines, the other day, and saw the TVN nymph, and thought there is something similar to the profile and color of the TVN nymph, what could be another reason for doing so well with the yellows.
It has also produced a good number of fish on still waters. When I was looking at the water boatmen, backswimmers and corixia images on the net the other day, I realised why. The basic profile is very close to the water boatmen, backswimmers and corixia. But the UV thorax, makes a very good air bubble impersonation.
Perhaps, for most fish, it looks, just too much like food, to not taste it.

an image of a corixia and water boatman. Easy to see why a still water trout will take the OSA as one of these

One or 2 guys have commented that the UV White Thorax, can create the illusion of a hatching insect. Whatever, it catches fish, and lots of them. that is the most important.
