Nicley tied dude. Looks very like my "standard" dry since April, a JT Olive ( or Olive CDC Dun, if you pefer) but I like the short body and sparse wing on yours. Have you used Muskrat or Mole on the body ?
Hooked (but lost near the net) a fish on Tuesday evening on a size 19 JT so it is still doing the biz
It is such a visible fly on the water too.
