PMD Series, Part 1

Over the next few weeks I am going to be showcasing a few PMD patterns that I use. This week I am tying a PMD nymph that has been working great on the Missouri for the last few weeks. It is a mix of a few different flies. A friend showed me on of his favorite PMDs and I thought I would add some little pieces to it. The epoxy bubble back, wing case and legs are borrowed from the JuJu patterns. PMD’s nymphs come in different color combos, from a mottled amber to dark brown. As they approach emergence they tend to darken up. This is why I use the dark brown thread on this pattern. This is a great fly to use pre hatch or even during a hatch…. Well.. There are beter ones to use during a hatch…. Part 2?

PMD? Pale Morning Dun AKA Ephmerella… What does this mean to you? They are one of the next items on the menu on the Missouri and your favorite river when it reaches 55 for a bit. You know them.. The mayflies that show up after BWO’s, slightly larger and a pale yellow color? Some times they have huge redish orange eyes. PMD’s. They have three tails, their hind wing is is set back from the leading edge of there main wing and has a angle in its leading edge. Want more on specifics on PMD’s?

Why did that brown refuse my bug? Oh boy! Had to many tails on that PMD dun! I should have paid more attention to You could drive yourself mad with all the information on his site… I love it!



PMDs….Trout love them and should not be over looked. The key to this fly is a slim abdomen with a slightly fatter thorax. Thread body makes the slim abdomen pretty easy and the X-Small ribbing keeps the whole abdomen slim. We all like slim abdomens and so do the trout! You also want the thorax to be slightly larger than say a PT. A real subtle way to add some bulk is with the epoxy bubble. The epoxy gives an appearance of bulk, transparency and some subtle trout eye catching shine. UV Knot Sense is my favorite trout tying epoxy. It works great on little bubble backs or any of your trout epoxy needs. A small bottle for $8.00 will last almost forever.

Tie up a bunch and go get'm!


  1. Big Country says:

    Great looking PMD nymph. Keep up the great patterns and videos

  2. Great video and pattern. I like the sound of the UV Knot Sense. In the past I have tied up a bunch of flies and then mixed up some 5 minute epoxy and tried to apply it to them before it gets too stiff. That’s not been too convenient as the longer it sits the harder it is to spread on the fly and not get too big of a bubble and also not have little “stringers” coming off of them. Can’t wait to try it.
