This is a good early season pattern for rainbow trout and a great pattern for grayling all summer long. Little green stones will hatch throughout the season in variable numbers depending upon altitude and river substrate. Normally they are more abundant during the late spring and early summer, however I’ve seen them coming off the water in February during mid-winter warm ups. Tie up a few as occasionally trout will key in specifically to this vibrantly colored pattern.
