The setae on the wings make it a big tricky to identify this caddisfly from the "splayed wings" view because they obscure the venation, but several of the side views provide a good look at the important forewing veins. It keys pretty confidently to Ironoquia. Based on species ranges and a photo on BugGuide seemingly of this species and some alternatives, it seems Ironoquia lyrata is by far the most likely option.
