Olsen’s Quilldigon – Olive – Barbless
From the designer, Devin Olsen:
Stripped peacock quills make perfect segmented bodies which imitate the natural color patterns on mayflies. The only issue is that they are fragile and often shred after a few fish. However, when covered in resin for a perdigon style body they make the perfect material for representing small mayfly nymphs. The Quilldigon features this naturally effective material combined with a turn of pearl flash at the rear to set it apart from natural mayfly nymphs in the drift. It has become one of my most reliable patterns anywhere that I fish. Small mayflies are nearly ubiquitous in trout streams around the globe and the effectiveness of this fly follows that pattern.

FAQ
What makes the Quilldigon different from other mayfly nymph patterns?
The Quilldigon uses stripped peacock quills covered in resin to create a natural segmented body that closely mimics mayfly nymphs. A turn of pearl flash at the rear helps distinguish it from natural nymphs in the drift, improving its visibility and effectiveness in the water.
Is the Quilldigon durable during fishing?
The quill body is naturally fragile and may shred after a few fish. However, the resin coating provides structural stability and maintains the pattern’s integrity during use, especially when imitating small mayfly nymphs.
Can this fly be used in different types of trout streams?
Yes, small mayflies are nearly ubiquitous in trout streams worldwide. The Quilldigon’s design closely matches natural patterns, making it effective in a wide range of stream environments.



Edward Davidson –
I’ve used the Quilldigon in several trout streams and it consistently catches fish. The olive color and pearl flash make it stand out in the drift without looking artificial. It’s a reliable pattern for small mayfly nymphs.
Una Bell –
The resin coating holds up well even after multiple casts. The segmented body looks very natural and matches the way real mayfly nymphs move. Great for dry fly patterns in slow-moving streams.
Edward Peters –
It works well in clear water streams. The pearl flash helps when the water is still. I noticed the body can be fragile, but the resin helps it last longer than expected.
