and Illinois
.
The wingspan
is 3.6-4.8 mm. There are two or possibly three generations per year. Full-grown larvae have been collected in June, August and September.
The larvae feed on Tilia americana
. They mine the leaves of their host plant. At first, the mine is within the parenchyma of the leaf and barely visible on upper surface. Later it broadens into a blotch or broad tract and becomes transparent. The frass
is deposited in sinuous curves.
