It is a frequent pest in commercial highbush blueberries in New Jersey. There are at least three generations per year.

The larvae feed on Rhododendron species, including Rhododendron occidentale. They mine the leaves of their host plant. The mine has the form of a tentiform mine on the underside of the leaf. The lower epidermis is wrinkled. Later, the leaf is rolled from the tip downward onto the underside of the leaf.
