Spotted Sedge Pupa (Hydropsyche)

A

Hydropsyche and Cheumatopsyche net-spinners are the season-long caddis from May through September on every Michigan river, and the Muskegon is 'world renowned' for them. Pupal wing pads darken a day before emergence; swing a tan or olive pupa on the rise toward dusk, or hang it under an Elk Hair. St. Marys Atlantics feed on caddis pupae from mid July.
