NymphMicro Madison Baetis
The Micro Madison Baetis is a small, precise mayfly nymph developed for the technical waters of the Madison River and similar fisheries. The Hungarian partridge tail, Baetis olive dubbing thorax, and opal mirage wing case combine to create a realistic Baetis nymph imitation. The copper bead adds weight without overwhelming the slim profile.

Overview
The Micro Madison Baetis was developed for the demanding trout of the Madison River where Baetis hatches bring fish to feed selectively. The pattern captures the essential elements of a Baetis nymph without unnecessary bulk. The opal mirage wing case adds subtle flash that mimics the gas bubble forming under natural nymph wing cases.

Fishing Tips
Season
Most effective during spring and fall Baetis hatches. These hatches often occur on overcast days and can extend through afternoon hours.
Presentation
Dead drift through seams and feeding lanes where Baetis nymphs naturally drift. Maintain precise depth control for selective fish.
When to Use
Best when trout are feeding on Baetis nymphs before and during hatches. The small size matches the naturals found on most waters.
Water Type
Designed for freestone and tailwater rivers with strong Baetis populations. Particularly effective in slower runs and along current seams.
Rigging Suggestions
Fish as a dropper below a larger nymph or in a tandem rig during Baetis activity. Light tippet (5X-6X) aids natural drift.
Visibility & Floatation
Sinks steadily with the copper bead. The opal flash helps fish and angler locate the fly.
