SOS Fly Tying Pattern by Spencer Higa's

Spencer Higa created the SOS fly pattern with Baetis in mind.  Once the red wingcase was added this fly took a turn toward an attractor style nymph while retaining its imitative traits.  Generally speaking, Baetis nymphs are dark in color with a slim profile and noticeable segmentation in the abdomen.  This is a quick tie, and will work great throughout the year with peak times during Baetis (BWO) hatches spring and fall as well as through the winter months when much of a river Trout's diet consists of baetis nymphs and midge larva/pupa.  Spencer also uses the SOS on lakes suspended under an indicator or retrieved, usually behind a larger fly like a leech or wooly bugger.
