In mid to late June the fishing on the Androscogin in NH is at its finest. One of the largest and easily recognized aqautic insects on this river is the stonefly. They seem to prefer fast moving water and the Andro has plenty of that. Here is something different to imitate or "suggest" an adult stone. Sometimes offering the trout something they have'nt seen before can really get thier attention. I offer these in sizes 6 and 8.
