The wingspan is 13–14 mm. There is one generation per year.[3]

The larvae feed on Betula alleghaniensis. The first two instars skeletonise the lower surface of a leaf of their host plant. They feed from beneath a sheet of silk that is constructed between two lateral veins. Third instar larvae move to the upper surface of a different leaf and fold it lengthwise. They then feed on the upper epidermis within the fold until the leaf falls down.
