Mine

The wingspan is 2.8-4.6 mm. Late instar larvae have been found in the middle of June, latter part of July and October in Cincinnati. Adults have been collected in May and late June to the middle of July, indicating that there are at least two and possibly three generations per year.

The larvae feed on Rubus species, including Rubus occidentalis. They mine the leaves of their host plant. The mine is a long, very narrow, serpentine tract on the upper surface of the leaf. The frass is deposited centrally as a dense black line becoming more diffuse in the distal fifth of the mine.
