Taxonomy
E. sulphurella was first described scientifically by J.C. Fabricius in 1775. Subsequently, the same scientific name was used for several other moths, creating a number of junior homonyms that are all invalid. These include:
 * T. sulphurella of Fabricius (1777) is Oecophora bractella
 * T. sulphurella of Hübner (1793) is Ypsolophus sulphurella
 * T. sulphurella of Haworth (1829) is Povolnya leucapennella
