Nymphs like giant stone flies live in the rivers for as long as three years before they hatch into winged adults. They are attractive to trout in several sizes, almost year round. As the stone fly nymphs grow they must take over a larger territory. Trout target on these vulnerable treats and will feast until gorged.
