Case-Bearing Moth

Small, horn-shaped structure that was moving about on the underside of a leaf. When I held it, the larva came out reaching for something to grab onto. When I put it on the leaf, it walked away. The horn-house seemed to be moulded rather than made from sticks or twigs stuck together. The Case Bearing Moths are of the Families Pychidae and Coleophoridae. I can't tell which one this is.
