Hatchfly fishing glossary
A period when aquatic insects emerge from the water in large numbers, triggering fish feeding activity.
A hatch is one of the most exciting events in fly fishing. When insects emerge simultaneously, trout shift into active, surface-oriented feeding — creating prime dry fly conditions.
