I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

This topic is about the Caddisfly Species Macrostemum zebratum
The "Zebra Caddis" is one of the most well-known caddisfly species, and one of the largest to produce high intensity hatches on our trout streams.It is also an important species for smallmouth bass. Gary LaFontaine wrote in Caddisflies about encountering Macrostemum zebratum on a large smallmouth river:
I never caught so many smallmouth bass on a fly rod before in my life.

Is there a photo of one? I've never heard of them or perhaps I know them by a different name.
