Ecology
The larvae feed on Potentilla caulescens, Rosa arkansana, Rosa canina, Rosa centifolia, Rosa glauca, Rosa pendulina, Rosa rubiginosa, Rosa rugosa, Rosa tomentosa, Rosa wichurana, Sanguisorba minor and Sanguisorba officinalis. They mine the leaves of their host plant. The mine consists of a clear corridor, often with a hairpin turn. The section before the turn often follows the leaf margin. The first section of the mine is entirely filled with frass. Pupation takes place outside of the mine.
