In early spring, the water begins to warm and bluegills and other sunfish leave their deep water sanctuaries and head to the shallows. For several weeks before they start breeding they patrol shallow water feeding aggressively as they build up their energy stores for the rigors of the spawning season. When water temperatures reach the low 60's the fish will begin staging in the shallows in the same areas that they will ultimately create beds and start spawning once the water temperature approaches 70 degrees.
Early in the morning, when the air and water temperatures are still on the cool side it will be a subsurface game. Nymphs, wet flies, and small streamers will all produce fish. My favorite patterns include wet flies like my panfish versions of the Pass Lake Special and traditional soft hackles. The drab flies that I used during the winter can be put back in storage. This is the time of year where color becomes an attractor. The flies I fish this time of year will always have a little splash of color. As far as streamers go the James Wood Bucktail is a big bluegill killer. Big bluegills, crappie, bass, and pickerel can't resist a JW Bucktail slowly retrieved through the water.
