LaFontaine Sparkle Pupa
Gary LaFontaine's caddis-pupa design using a translucent Antron-style veil to suggest the emergence envelope.
- Common size
- #12–18
- Colors reviewed
- olive, tan, cream, amber
- Imitates
- ascending caddis pupa, emerging caddis
A sparse translucent synthetic veil surrounding the body is the defining idea. Deep Sparkle Pupa and Emergent Sparkle Pupa forms differ in wing, weight, and fishing level and remain labeled variants.

On the water
Understand it. Then fish it.
The river, depth, insects, and fish behavior still decide the final presentation. These are reviewed starting points—not a claim about what is happening today.
How to fish it
- Dead-drift, then allow a controlled lift or swing.
- Use weighted and unweighted forms to follow the stage.
Mistakes to avoid
- Treating deep and emergent forms as identical.
- Packing the veil so densely that it loses translucence.
Variant control
Small changes matter.
Three reviewed technical illustrations show the identifying profile, construction, and fishing orientation. They are schematic field-guide aids, not photographs.
