Learn to Paint Cracks
|Crack Back PMD -- Aero Style|
Pale Morning Duns, or PMD's, are sometimes an overlooked bug on a lot of rivers I've fished, but it's still a good idea to have a variety of imitations for these common and important mayflies. Not only do they bring a lot of fish to the surface at times, but unlike the Baetis hatch, my experience early on showed me that trout often focus more on the emerging insects which turned my focus more towards a good variety of emergers and soft hackles. In fact, one of my favorite PMD patterns is a floss bodied soft hackle pattern a friend of mine ties. Between that and seeing how distinct the naturals showed their bright yellow bodies as the wing-case would begin to split open, I worked to come up with a good material to use for the "crack". I went through almost any yellow or chartreuse material you can imagine. Most would lose their color brightness when wet. I ultimately settled on some antron but more recently converted my updated Aero-Baetis style mayfly nymph into this crack back we have today.
The key here is that with Baetis or PMD nymphs and emergers you need to keep the body slim and the taper consistent with the natural. And because I'm a big believer in crack-back style emergers, I've taken that concept and applied it to this pattern, albeit a bit differently than others you might have seen. Which probably means it won't work and you'll waste your time tying this horrible pattern.
