Pale Morning Dun Midge

The PMD Midge pattern is not a literal midge but rather a tiny mayfly imitation (usually size 20–24) that mimics small Pale Morning Duns on tailwaters or spring creeks. It can also pass for a chironomid in the appropriate coloration.

History:
As fly design has trended smaller and more realistic, this downsized PMD imitation gained popularity on technical waters where fish feed selectively on tiny duns or cripples. Often tied with sparse dubbing and CDC or soft hackle for realistic presentation.
