question
This is neat! I have never seen these larvae before - is there some character in this photo that helps distinguish this from Polycentropus? Have these been reared to determine species?

Key
I used the Trichoptera key in Merritt et al.(1) Long, narrow prothoracic tarsi(at least 2/3 length of tibia) and strongly curved anal claws distinguish Cernotina from Polycentropus.
