“Vernon S. “Pete” Hidy coined the term flymph. What is a flymph? A flymph is a hatching insect be it mayfly, caddisfly, midge, or stonefly that according to Pete Hidy is in the stage of metamorphosis “changing from wingless nymphs to flies with wings”. These flies are historically fished with a across and downstream technique that allows the current to naturally swing and raise the fly up to the surface in front of a rising or holding fish in a manner that activates the soft hackle collar and body materials effectively imitating life in the ascending artificial fly. The attraction of these flies is that not only do they look natural but they behave natural as well. They have movement; they have the appearance of life.”
now, the last part to me is probably the key element when considering constructing these flies: “the appearance of life’ (even though the real bugs could be stillborns or spents, their leg/body/wing parts would still move throughout the drift downstream)
“Traditionally flymphs are tied with natural body materials that will undulate in the currents. These body materials include hare’s mask, peacock, muskrat, mole, squirrel, and other natural fur with guard hairs. Shaggy body materials like rabbit, hare, and squirrel hold water well, sink quickly and also capture small air bubbles when they penetrate the surface film. These air bubbles create shimmer and sheen and look particularly similar to caddis pupa which uses internal gases to propel them to the surface or egg-laying caddis that dive underwater to lay eggs and carry with them oxygen bubbles for respiration. The hackle collars of flymphs are chosen with color and movement in mind to match the emerging wings, antennae, and legs of the ascending nymph. Soft, webby feathers such as hen, partridge, grouse, starling, woodcock, or quail are choice. These feathers absorb water and each has it own unique action underwater.”
