The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
This large species of Paraleptophlebia is one of the tusked group. Records indicate it is endemic to California where it fills the niche taken by Paraleptophlebia bicornuta in neighboring states. It usually hatches with the more common and very similar looking duns of Paraleptophlebia debilis.
