Pteronarcys californica...what?

For the past few weeks, the Henry's Fork has been the choice destination for traveling anglers in pursuit of the famous salmonfly. After living in the river for up to three years, these insects migrate toward the banks to transform into their adult form...mate...and then die. This hollowed "hatch" can provide the best dry-fly fishing of your life, or be the biggest let-down of your season.
