Trico Dun & Spinner Pattern
Depending on the river you’re fishing, you can expect to see these little devils anytime fron mid-July until almost the end of September. A bonus for tiers is that imitations need only be the right proportion, and close in color.
I suppose you can say that of almost any dry fly 
, but i’ve seen entire trico dries made of tying thread with a gob of CDC on top. For all of the anglers who might turn on me with tales of fussy tricorythode-eating trout….yes…. I know it happens. Like most hatches, low-riding sparse ties will usually do the trick. They are often taken (in my belief) as emergers and/or duns. In fact, last September on the Ausable river in NY I stumbled upon what many anglers have know about this hatch for some time~the trout will often key-in on submerged duns! (those that have hatched, are either still-born or drowned before they ever take flight) I’ve yet to actually add weight to my trico duns, but i’ve read that lots of tiers do.
The best trico fishing i’ve had has always been in the early morning. They are not diffucult to spot when mating, or when on the water. I always start with the dun featured below, the spinner when when they outnumber the duns.
Tying The Trico Dun & Spinner Fly Pattern
Trico Dun
Hook:Tiemco 101 size#24 (or standard fine wire dry fly hook)
Thread:Tan and black 12/0 (8/0 is OK, but can add bulk quickly)
Tail:Coq de Leon (pardo medio) microfibbetts or spade hackle in dun-color is fine
Abdomen:pale olive goose biot
Thorax:Black superfine dubbing
Wing:Light dun CDC
Trico Spinner
Hook:Tiemco 101 size#24
Thread:12/0 Black
Tail:Coq de Leon
Abdomen:Stripped peacock (from the "eye" feather)
Wing:Organza
Thorax:Black superfine dubbing
With tan thread, wind back to the hook bend, tie-in 3 tail fibers. "Splay" them out so that they appear like the naturals. Add a very small drop of diluted head cement at the base of the tail.
Tie in the goose biot (with the notch at the base of the biot facing back) and wind forward. Tie-off. Switch to black thread.
Dub a bit of the black at the tie-off point. Select 2-3 CDC feathers and align the tips. Tie them in at the angle shown.
Add a bit of dubbing in front of the wing to hold it in position, tie-off. Add a tiny drop of diluted head cement to the tie-off point.
Spinner. Tie in tails as before. Using a pencil eraser, remove the "fuzz" from a pc. of peacock herl. Tie it in, wind it forward to create the abdomen. Cut a strip of organza about 3/8" long, pinch and pull a clump of the fibers off and tie on where shown, making figure-8 wraps of thread.
Dub a thorax as shown, again in figure-8 wraps to support the wings. Tie-off, add a drop of head cement as before.
