I came about this belief by accident a few years ago. Now I never go trout fly fishing without a bunch of yellow dry flies and nymph flies.
I believe in the matching the hatch and for the most part agree with it. However at times I step that concept and offer the trout what might seem like a complete contradiction to that rule. Have you ever been on a stream or river and watched a huge hatch on the water with only a few trout feeding. With thousands of flies on the water and only a few trout feeding on them what are your chances that one will choose your fly? A few years ago I watched a large hatch and did not have the right fly with me. Instead used Female Adams dry flies that were a little similar to the flies that was hatching except that the female Adams trout dry fly is tied with a little yellow at the tail end of the body that simulates an egg sack. With my female Adams I caught three nice rainbow trout before my friend caught his first. Since then I have tried female Adams flies, yellow Humpy Deerhair flies, yellow Dun flies, Sulphur Dun flies, and even Yellow Sally flies with amazing results.
Another time I will use on a yellow fly is when there are no hatches and nothing seems to be working. When this happens, try using a few yellow dry flies. The yellow color seems to stimulate fish that are not actively feeding to strike. If you can’t coax a fish to the surface to take a yellow dry fly than try a yellow or olive nymph fly. The yellow dry flies and nymph flies also seem to work well when the water is stained and a little muddy.
I want to talk more about the female Adams dry flies again. The Adams dry fly resembles many other fly hatches. The female Adams with the yellow egg sack is probably the deadliest fly you can have with you. When I expect to catch trout feeding on dry flies I always have at least a dozen female Adams flies with me in various sizes and it is always the first fly I tie on my line.
Tight lines and clear water,
Brian
