    Emerging mid-morning to noonish on lower North Fork Stilly in head of pool below long, shallow glide. A fair-size mayfly, not BWO-size by a long stretch. Duns with a green/yellow cast to their dramatically segmented abdomens. Look to me to be an Ephemerellid, as they are kinda chunky. Approx 1/2 inch long, excluding tails. The cutts are loving them!

    Hi fishwater-

    Sounds like Western Green Drake (either Drunella or Timpanoga) to me.

    Here's a picture from just over a week ago on the North Fork. My first guess was Drunella flavilinea.
