UV

[Roadkill]

Flies tied with a bit of UV do seem to catch more fish. I tied some $3 Dips using some UV Pearl Ice dub for the wing instead of deer hair. Fished both flies in tandem and the UV fly out fished the non-UV fly every time, no matter where on the leader it was.

I tied Bead Head Krystal Dips I found in the Slide Inn catalogue before staying there 13 years ago, and found they performed better than the $3 dips, even at the bridge. Tied with Pearl Krystal Flash (no UV bling) they are still a favorite in my boxes along with the plain originals.

Note: The Peacock KF is UV Fluorescent. Maybe that helps to explain the Smurf Emerger!

It kind of sounds like the idea that trout lose the ability to see UV when becoming adults is a fantasy. No matter what studies say.

DUBBN,

Fluorescent colors are light visible to the eye emitted when UV is absorbed by something. You don't have to see UV to see those bright colors.

I am pretty sure those studies say otherwise about adult trout

I've been following this conversation to see if I missed some of the hype over the years.
I agree that in murky waters fluorecsent and UV does make a difference in certain conditions.
In gin clear waters, I'm not so sure. To me, it depends on light conditions, refraction, turbidity.
I also think that fish key on reflective emergers but shy away when a hatch is not in progress.
