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.

OD-
Water penny beetle larvae feed on periphyton, a complex mixture of algae, cyanobacteria, heterotrophic microbes, and detritus coating the rocks to which they attach themselves. The adults are not aquatic.
