I’ve been using this fly here in Central Idaho with great success.  It seems to be a good imitation for adult golden stoneflies.  I can’t take credit for the invention of this fly…I found something like this a fly shop here…I don’t remember which one or what the original version of this fly was called.  But, I’ve modified it a little to match the smaller adult golden stoneflies that we’re seeing in late June.  Mary Ann has been calling this pattern the Chubby Junior…even though it has no resemblance to a Chubby Chernobyl…the name sounds fine to me.  Here is the recipe:

Hook:  #8 2X long

Tail:  Tan Calf Tail

Body:  gold dubbing with 2mm tan foam on top

Wing:  12 strands of white crystal flash, with tan calf tail on top

Head/Thorax:  2mm tan foam

Leggs:  Brown Rubber

Hackle:  brown
