  A huge rainbow trout even with hooked jaw ... caught on a dry fly ! To experience the benefit of a mayfly (E.Danica) hatch, it is not always mandatory to fish on the most known chalk streams. Although only this last type of rivers can offer the "spectacle" of thousends of insects hatching togheter, the ephemera danica is often present, less massively, in many rivers in our continent.
