• At its most simple, if you are fishing early spring (doesn't have to be March), and you see a hatch sometime midday, and the color is somewhere in the brown category, you best be prepared.
• This pattern is medium brown, also covers Brown Drake.
• Many places this will be the first significant dry fly action after the long winter.
