Stigmella argentifasciella is a moth of the Nepticulidae family. It is found in Ohio, Kentucky and Illinois. The wingspan is 3.6–4.8 millimetres (0.14–0.19 in). 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.
