Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

Southeast Minnesota was ravaged by floods this weekend. Their was an incredible 16 inches of rain in a 24 hour period in a town called Lewiston. Six people have died in the flood waters. There is one marginal stream that I'm very concerned about. It doesn't have very good natural reproduction to begin with and when i saw boulders 50 feet or more on the bank i don't think the trout could have done very well, let alone the streams invertabrate population.
