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.

Biography & Thoughts
My interest in identification of aquatic insects developed as a natural byproduct of transitioning from other methods of fishing to fly fishing during my early 40�s. However, it was not until my retirement, which followed a 35-year career in information technology, that I was afforded the opportunity to fully pursue study of aquatic entomology and taxonomy.
Within several years following retirement, I had accumulated an enormity of texts and notes on aquatic entomology and taxonomy. And, it was becoming readily apparent that some manner of organizing and accessing that information was sorely needed, as accurate memory of minutia was definitely not my strong suit.
My initial approach was to organize all the information in an Access database, but it didn�t take long to realize that this approach (alone) would not allow sharing the information with other flyfishers. So, I developed a website, which was initially just many entomology-related pages on the website of the flyfishing club to which I belonged. However, as my ever-increasing need for storage began to cause a problem, I took the big plunge, and got my own domain name and hosting provider. To date my website has received in excess of (300,000) separate visits, from (125) countries, representing all (6) inhabited continents.
