How to Rig It
Single dry on a stout 9 ft 2X-3X leader. Bank-bash tight to structure and overhanging willows.
How to Present It
Slap it tight against undercut banks and twitch the rubber legs. Black stoneflies fall in clumsy from streamside vegetation — a hard splat is the trigger.
Why It Works
The big black foam silhouette stands out on any water; rubber legs trigger surface strikes. Black stoneflies emerge for weeks in spring, and trout hold tight to banks waiting for them — bank presentations are deadly.
History
Modern foam-bodied stonefly dries evolved from the Sofa Pillow and Stimulator. The all-foam construction floats forever and supports heavy droppers when needed.
Pro Tip
Pre-hatch (March-April), fish a black stonefly dry tight to the bank as a searching pattern. Trout that haven't seen a dry fly in months can't resist a big black silhouette dropped right next to their lie.
