Rhyacophila (Green Sedges) Caddisfly PupaRhyacophila (Green Sedges) Caddisfly Pupa View 2 PicturesEven though I already have pictures of a Rhyacophila pupa in its cocoon, I took this one and then tried to keep the pupa alive, hoping to photograph it in several stages of development. That didn't work out; it seems to have died without changing much. Oh well.
