It's Spring baetis time ( or will be soon where you are).

This little bug is so important in the waters I most fish that I'm always on
the look out for new patterns based on it. Often, just "something
different" can be a big factor in heavily fished areas, during hatches the
fish get to know well.

Got any favorite but unusual "Blue Winged Olive", just plain "Olive", or
baetis ties ?
