Tube Maker Caddisfly - Cernotina spicata

Tube Maker Caddisfly - Cernotina spicata
Pine Lake, Gravenhurst, Muskoka, Ontario, Canada
July 2, 2011
Size: 10 mm
Ontario data point. Collected in benthic dredge.

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?

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.
