The most common genus we encounter is Polycentropus. These caseless caddisflies frequently have speckled or freckled heads. The anal proleg typically has a prominent black X, although it can in some specimens appear to be a little faded. They are common at Oakledge Park in Lake Champlain, where we also find an additional genus in the same family: Nyctiophylax.
