BWO

For the past several days I have been witnessing some exciting BWO hatches on the streams of the Driftless area. Here is the imitation I prefer to fish any time BWO's are hatching...

Hook: TMC 531 (size to match the naturals-this is 1X short hook)
Tail: olive angora/lite -brite blended dubbing (short) and wood-duck fibers (long)
Body: olive turkey biot
Thorax: opossum dubbing, slightly teased out
Wing: grey rabbit foot hair (or natural cream, for visibility)
