It's easy to get drawn to flashy, oversized flies — streamers, hoppers, big nymphs — but when things get tough, small flies often save the day.
Here's why the little guys matter:
1. Fish Eat Small Stuff... Constantly
- Most of a trout's diet is made up of tiny insects like midges, BWOs, and small mayflies.
- Especially in winter, late summer, or heavily fished waters, fish key in on small patterns because they feel natural and less threatening.
2. Pressured Water = Picky Fish
- In popular rivers, fish see everything. They've been fooled before.
- Size 20–24 midges, emergers, or soft hackles often get hits when bigger flies are ignored.
3. Subtle Wins
- Small flies = subtle landings and more natural drifts.
- They're especially deadly in calm water or when fish are sipping gently at the surface.
4. Use the Double Rig Trick
Pair a small fly with a slightly larger one:
- Attract with a big nymph, but let the fish take the tiny dropper.
- Bonus: you can cover multiple water depths in one cast.
5. Gear Up Right
- Use lighter tippet (5x–7x) to present small flies without drag.
- Keep a hook sharpener handy — small hooks dull quick and miss easy.
Pro Tip:
If fish are rising but not taking your dry fly? Try a size 22–24 CDC midge or a parachute emerger. Watch what happens.
