This is an uncomplete and ongoing effort to photograph the macroinvertebrates that trout consume in S.E. Minnesota. Below are groupings of images that will be expanded upon as time passes, some contain specific hatch information and a summary of what I witnessed last season. I hope this is helpful as a reference for fly tyers who want to better imitate the natural insects we have in our area.
