Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

I was looking at an old FlyCraft paper caliper device. I never used one myself, but have seen them.
My question is this: how many believe the Golden Ratio applies, for example , to the placement of the wing on a hook?

I have watched many highly respected tiers place the wing at the 75% mark of the shank length (for example). Others, say to place the wing at "...approximately the 2/3 mark of the hook shank."

If the Golden a Ratio applies to this aspect of an insect's wing location represented on a hook shank.....and if I have done the math correctly, it would fall at the 62% mark.

I'm not talking about some Balancing reason, but strictly trying to imitate the appearance of the natural.

Your thoughts?

Hi Byron-

Your thoughts?

Not to imply that I have any useful thoughts, but simply in the interest of clarifying your question, are you referring to mayflies?
Best regards,
Roger Rohrbeck

Any mayfly.

Here's a photo of the old device.

I was relating this post to Fibonacci's Number, which corresponds to 61% more or less...I use it a lot in cabinet-making, my other $$$$$ vice and semi-retirement it's supposed to make money hobby.
I'd like to see a good side-view (elevation, so to speak) of a given natural but it makes sense that the proportions apply, somehow.

Welcome to the Forum, you've been here a while but hi anyway!
