Grannom Pupa

A

Brachycentrus emerges in intense afternoon bursts once water holds in the low 50s, from late April on Michigan charts (Mother's Day caddis), a week or two later in the U.P. Swing or dead-drift a green-bodied pupa toward the surface in the hour before the adults appear, then fish it as a dropper behind an Elk Hair Caddis.
