Uses

Imitates the nymph stage of pale morning dun mayflies.

 
PMD nymphs are naturally slim, as well as small. Many traditional nymph patterns are too thick and don't match the natural insect's profile. This thin, sparse pattern looks more like the real insect than many commercial patterns.

 
By varying the size and color slightly, other small, slim nymphs can be imitated, such as blue-winged olives and Callibaetis.

Variations

To match blue-winged olives, use size 16-20 hooks. To match Callibaetis, use size 14-18 hooks.

How to Fish

In rivers, use the indicator, tight line, rising nymph, or shallow nymph presentations. The first three are suited to beadhead versions of the nymph. The latter presentation is usually used with non-beadhead flies

 
When imitating Callibaetis nymph in lakes, the slow retrieve. presentation is most useful. Use a non-beadhead fly.
