The second documented larval habitat for the northern caddisfly Phanocelia canadensis (Banks) (Trichoptera: Limnephilidae) is far south of the usual range for this species. We have collected larvae consistently over the past five years from two of fourteen small kettle-hole depressions in glacial outwash sands and gravels on outer Cape Cod, Eastham, Massachusetts, USA. The larval life cycles and behavior are similar to those reported from the New Brunswick population studied by Fairchild and Wiggins (1989). Habitat characteristics distinguishing the wetlands inhabited by Phanocelia from those where larvae are not found include low pH and dominance by Sphagnum.
