Caloptilia blandella is a moth of the family Gracillariidae. It is known in Canada (Québec) and the United States (including Pennsylvania, Virginia, Maine, Maryland, Texas, and Kentucky).[1]
The wingspan is about .
The larvae feed on Carya ovata and Juglans nigra. They mine the leaves of their host plant. The mine has the form of a little crooked, very narrow mine resembling a small snail's track. It is found on the upper side of the leaf. Later instars create a leaf cone. It involves only one fold of the host leaflet, and therefore, extensive skeletonization can be seen on the exterior of the fold. Often, the fold is located on the margin of the leaflet rather than at the apex.
