Looks like a Racklehane Variant:From the vise of Poul Jorgensen, Roscoe, New York. Poly Caddis Emerger
Hook: Pictured is a size 14
Body and wing: Brown poly yarn. That’s it.
Jorgensen (who was known for his exacting, realistic ties) highly recommended this ridiculously simple pattern. Maybe he was just cleaning out his caddis box when he gave it to me in Basalt.
