Gary, may I ask how you ID these caddisflies? Do you have a specific guide that you use, or get assistance online, just research them, etc.? I could use some tips. Trichopterans are really tough for me to get to species level, but I see while mothing and would love to get better at identifying them. Posted 6 years ago

  I rely on Bug Guide primarily going over their record of confirmed id's. Also Tom Murry's photos at Pbase. As far as guide books there don't seem to be any except for a few technical volumes that are out of my price range right now. The Glyphopsyche irrorata was confirmed for me by an authority on the genus using a photo although Bug Guide is still in doubt. I am sending him specimens I collected last fall for verification. There are papers on Trichoptera and while many lack illustrations they do contain descriptions which I use to help me figure them out. This paper does have some illustrations with descriptions and is good for the Upper Midwest at least: Houghton DC (2012) Biological diversity of the Minnesota caddisflies (Insecta, Trichoptera). ZooKeys 189:
  1–389. doi: 10.3897/zookeys.189.2043
  
  I think I have a handle on the divisions within Trichoptera and can recognize the northern caddisfly group somewhat consistently. I'm pretty confident about recognizing these genera: Oecetis, Triaenodes, Pycnopsyche, Ptilostomis, Limnephilus, Nemotaulius, and Platycentropus. Posted 6 years ago

    I am not at all confident IDing them, but hopefully will be at some point. But, it's great to have you here, sharing your knowledge! I'm hoping to get out in some streams this spring to photograph some caddisfly larvae (and other aquatic insects). Their cases are so fantastic! Posted 6 years ago
