In late fall, I located a spindle-shaped swelling (~35-45mm in length) in the distal portion of a basal leaf petiole, just below the base of the leaf blade. The shape of the swelling and the internal fungal blackening it contained were both typical of Neolasioptera, but I did not open the swelling enough to observe larvae directly.
