Missouri Hatch Chart

Here is the Missouri hatch chart for our State.  Many of these hatches are happening at the same time in other states as well.  The imitations suggested are just that – suggestions. Flies that you have that may be similar would work also. Remember when the specific aquatic insect (caddis, mayfly, or stonefly) is hatching their nymphal and larva stage are present as well.  Midges are year round so don’t forget to fish with them.
