The Psycho May is one of the most lethal mayfly nymph patterns on the Missouri River and should be a part of your nymph rig system. Traditionally used in a tandem nymph set up, this pattern can also be used as a dropper below a good sized dry fly. The olive pattern is great during the Spring and Fall baetis/bwo hatches. The pmd pattern is a definite go to pattern during the pmd hatches mid summer. If you choose to get our Missouri River Assortment, you’ll most likely see a few of these in there.
Not all sizes are available in both colors.
