Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington

I browsed through the insect pictures but I am not very good at what things I am looking for that separate the different types of bugs. Can anyone tell me what this is??? Also, pics of a nice brookie and brown.
