The following flies follow something I lean toward often, but not always, the notion that an active or mobile spider is a better imitation of a natural and size, shade and texture play critical roles. That being said these patterns are not necessarily hatch specific but more along the lines of attractors. A case for specific matches could easily be made, but the intention is to carry a similar construction in three shades. (too wordy? I know, it's been a while since I've posted.)
The Light Twist - bleached turkey twisted with primrose silk and a speckled hen hackle.

The Medium Twist - golden pheasant tail herl twisted with orange silk and a grouse hackle. Sub partridge or woodcock for the grouse.

The Dark Twist - the classic Leisenring Black Gnat twisted with crows fibers and claret silk and a Starling hackle.

In a fit of ocd/meditation/avoidance I tied three dozen of the medium with a turkey tail herl and ginger variant hackle.
