Had a visitor on the screen today. Gave me the opportunity to get a couple good pix of the fishies view of a PMD spinner. The overall length of the body is 5/16".





A couple things that seem particularly noteworthy are ( 1 ) how vague the wing is, almost to the point of being invisible, in the upright position and ( 2 ) how long and splayed the tails are.

I don't fish a lot of PMD hatches on the streams I like to spend time on, but patterns that I would tie based on this model are markedly different than a lot of flies commonly offered as PMD spinners.
