Apple Caddis and Grannoms
This common name refers to only one family.
Caddisfly Family Brachycentridae
These are pretty much always called Apple Caddis and Grannoms.
Brachycentrus is one of the most important caddisfly genera in America. Microsema is smaller and rarely, if ever, significant. Amiocentrus aspilus can be an important Western hatch.

Brachycentrus (Grannoms) Caddisfly Pupa
View 10 PicturesThe green blob contained in this case is a pupa in the early stages of transformation from larva to the final stage we generally picture and imitate. This specimen and several like it were fixed to a rock I picked up, and each one had the front of its case sealed off, protecting the helpless pupa from predation. It's neat to see the insect part-way through such a radical transformation.
It was very hard to extract this thing from its case, so there's a bit of extra goo near the head from where I accidentally punctured it.
