Leptoceridae Caddisfly AdultLeptoceridae Caddisfly Adult View 17 PicturesThis specimen keyed easily to Leptoceridae, but I hit a bit of a dead end in the genus key, because I can't seem to find the cross-veins in the wings that are supposed to help narrow it down. I took pictures of all the relevant features under the microscope; maybe somebody with more experience with the family can help.
