I don't get excited about fishing egg patterns like some fishermen do. But, there's good reason for their excitement: they work. It's a simple fact.

Anglers aiming to imitate eggs in the water generally have two options in the world of fly fishing: the more traditional yarn-based egg patterns such the Glo Bug or the more recently adopted plastic bead egg imitations.
