What Egg pattern means
Eggs drift downstream after trout, salmon, or steelhead spawn, and fish treat them like a high-calorie food item. An egg pattern is tied to match that look, usually as a bright, round “single egg” or a slightly larger clump.
Most anglers present an egg with a dead drift near the bottom, often under a strike indicator or in a tight-line nymph rig. It is commonly paired with a second fly, like a nymph, to cover both eggs and insects in the same drift.
Why it matters on the water
Egg patterns are one of the clearest examples of fish feeding on something other than insects. If you see active spawners, redds, or fish stacked below a spawning area, an egg imitation matches what is actually moving through that lane.
They are also a good tool for learning drift and depth control. If an egg is ticking bottom occasionally and moving naturally, it is in the zone, and that same setup usually improves your nymph fishing with other patterns.

- NymphA nymph is a subsurface fly meant to imitate an aquatic insect in its immature stage, or a small food item drifting in the current. Nymphs are fished with or without weight, an indicator, or tight-line methods.
- San Juan WormA San Juan Worm is a simple chenille worm imitation used as a nymph, usually dead-drifted near the bottom for trout and other freshwater fish.
- Strike indicatorA strike indicator is a small float or marker on the leader that shows takes and depth while nymphing. It moves, stalls, dips, or shoots sideways when the flies get bumped or eaten.
- Sucker spawnA sucker spawn is an egg pattern that imitates loose eggs drifting downstream after suckers spawn. It’s usually tied as a small cluster of eggs rather than a single bead.
