Fishing emergers is like dry fly fishing, the emerger fly pattern like dry flies but are not high floating but are designed to imitate aquatic insect larvae that are in the process of metamorphosing into flying insects and are trapped in the surface film. When the larvae mature, they ascend upwards through the water column and get trapped in the water's surface and have to break the surface of the water film. The meniscus forms a bit of a barrier to tiny insects and they often wiggle around enticingly as they push their way through and open their wings for the first time. This makes them very vulnerable to surface trout feeders and, at times, the fish will lock onto these emerging insects and take little else. Emerger patterns imitate this life stage and help you match-the-hatch when fly fishing to increase your catch rates. The best time to use emergers when fly fishing is when fish are taking flies on or near the surface. If the fish are rising and taking flies off the top, try an fish emergers. However, often you'll be able to persuade trout to rise for an emerger, even when there's no visible surface activity. When fishing emergers a delicate presentation is needed to let you place your fly (or flies) near the rising fish, so cast gently and use a long leader of 12 feet or more, if you can handle longer. When fly fishing emergers I'd recommend using a fan casting technique to cover the area all around your current position and placing your flies on the surface for 10 seconds or so, before gently peeling the line off and recasting elsewhere.
When fishing emergers you can give the fly a little twitch to immitate the emerger trying to break through the surface film. Fly fishing with emergers will broaden your dry fly fishing skills. The emerger pattern is a must have in your fly box.
