The first two fly patterns that I want to share fall into the ladder group described, and are flies that I've found monumental success with in the past few seasons regardless of not being specific imitations.
First, the almighty Royal Trude. If I was forced to select just one fly to fish with on any given day or even season, I would hands-down select this fly. I've caught fish in great numbers during prolific mayfly hatches, on mountain lakes with a wide array of much smaller insect activity, and in about all points in between. This is a "must have" in any fly angler's box, and there are a number of acceptable variations to materials listed. Photo and recipe are here:
CDC Royal Trude:
Thread: Black 8/0 Uni-thread
Hook: TMC 100 Size 12-16 (12 shown)
Tail: Golden Pheasant Tippets
Abdomen: Peacock Herl, Red Floss, Peacock Herl (alternated as shown)
Wing: Paired White CDC feathers, tied down-wing style
Thorax: Furnace or Brown Hackle
Next we have the stimulator, or in this case, the "foamulator". This fly is another fantastic tool in my arsenal because it is large and easy to see, works as a credible stonefly and/or hopper imitation, and has enough flotation to easy drop a nymph underneath on a dual setup. This fly is also especially sentimental to me because it is tied using hair from the Deer that I harvested this fall! Photo and recipe are here:
Foamulator:
Hook: Mustad long-curved 8-16 (#10 shown)
Tail: Natural Deer or Elk hair
Abdomen: Yellow closed-cell 2MM foam
Rear Hackle: Grizzly saddle hackle
Wing: Same as tail
Thorax: Peacock herl
Front Hackle: Furnace or Brown hackle
