Early Spring Hatches

Mayfly Hatching Cycle

1. Trout may focus on mayfly nymphs as they swim to the surface prior to hatching. Subtle boils and flashes in the water, combined with a few duns or freshly hatched mayflies on the surface, should alert anglers to this.

2. Nymphs can have a difficult time breaking through the surface to hatch. Some will pause and rest just beneath it, recouping their strength. This is when a floating or subsurface nymph (which can be fished as a dropper) can work best. If swirls but no trout noses are seen, or if trout backs and fins but not heads are seen, the fish are probably focusing on these.

3. Some trout may focus on mayfly emergers just as they struggle out of their nymphal shucks. This varies from fish to fish and hatch to hatch. Fishing pressure affects trout behavior, too. Many emergent patterns are offered by shops and cataloques these days. Most are designed to be partly on top and partly beneath the water.

4. The dun finally gets out if its shuck and steps up onto the water's surface. How long this takes, and how long the dun rides serenely on the surface if long at all), varies from species to species.
