Midge / EmergersBaetis Foam Emerger
The Baetis Foam Emerger is a buoyant emerger pattern that uses a foam wing pad to keep the fly suspended in the surface film. The grey foam mimics the developing wing case of an emerging BWO while providing reliable floatation even after multiple fish. The slim dubbing body and trailing shuck complete the emerger silhouette.

Overview
The Baetis Foam Emerger was developed for extended fishing during heavy BWO hatches where traditional patterns lose floatation. The foam wing pad provides unsinkable buoyancy while maintaining a realistic emerger profile. This pattern is particularly effective on spring creeks and tailwaters where fish see heavy pressure and become educated to standard patterns.
Pattern Characteristics
Materials
Hook: Tiemco 100 or Umpqua U001, #18-22
Thread: Uni-Thread, 8/0, olive dun (or Gordon Griffith's 14/0, olive)
Shuck: Crinkled Zelon, dark dun
Body: Superfine Dubbing, grey olive
Wing Pad: Evazote Fly Foam, grey
Hackle: Dun dry fly hackle, medium or dark
Fishing Tips
Season
Most effective during spring (March-May) and fall (September-November) Baetis hatches. The foam construction makes it ideal for extended fishing sessions during heavy emergences.
Presentation
Dead drift in the surface film with occasional twitches to mimic a struggling emerger. The foam keeps the fly riding properly even without floatant, making it ideal for covering lots of water.
When to Use
Best when fish are keyed on emergers in the film rather than fully emerged duns. Excellent for long sessions when you need a pattern that maintains its profile fish after fish.
Water Type
Ideal for spring creeks, tailwaters, and technical freestone water. The foam construction allows fishing in choppier water than traditional emerger patterns.
Rigging Suggestions
Fish on 12-15 foot leader with 6X-7X tippet. No floatant needed on the foam, but a light application to the hackle can help. The buoyant design supports a small midge dropper.
Visibility & Floatation
Excellent floatation from foam construction. The grey foam wing pad provides visibility while maintaining a natural appearance. Floats all day without waterlogging.
