A stage-first guide separating bottom-oriented nymphs from emerging and adult stonefly patterns.
- Size range
- Varies widely by species and river
- Colors reviewed
- black, brown, olive, golden, yellow

- View
- stage or silhouette comparison
- Color shown
- black, brown, olive, golden, and yellow
- Look for
- broad two-tailed nymph; emerging or crawling form; long folded-wing adult
On the water
Narrow the family.
The river, depth, insects, and fish behavior still decide the final presentation. These are reviewed starting points—not a claim about what is happening today.
How to fish it
- Fish nymphs near bottom; fish adult patterns near banks and likely emergence water.
Mistakes to avoid
- Using one dry image for nymph recommendations.
- Assuming every stonefly is large or golden.
Variant control
Small changes matter.
This comparison separates materially different insect, stage, or pattern forms. It is a family guide, not a claim that one fly represents every local species.
