The Hotwire Caddis – Olive is a super caddis pupa pattern that sinks fast and has a metallic sheen along the abdomen from the wire to imitate the naturals. It has been a proven performer for us here at the shop on numerous rivers over the years. The Hotwire Caddis – Olive is a great fly to fish all summer long and perfect under a hopper, stone or other large dry fly as a dropper.
