Stigmella rolandi is a moth of the Nepticulidae family. It is found from Germany to the Iberian Peninsula, Sardinia, Italy and Greece, and from France to central en southern Russia. It is also present in the Near East.
The wingspan is 3.7–4.7 millimetres (0.15–0.19 in) for males and 4.1–4.2 millimetres (0.16–0.17 in) for females. Adults are on wing from early June to early September. There are probably two generations per year.
The larvae feed on Rosa pimpinellifolia, Rosa rugosa and Sanguisorba minor. They mine the leaves of their host plant. The mine consists of a rather broad corridor that often follows the serration of the leaf margin. The frass line is quite broad, especially in the first part of the mine.
