The length of the forewings is 3.3–3.9 mm for males and 3.3–3.5 mm for females. Adults are very similar to Elachista hiranoi, but can be distinguished by differences in coloration of the forewings. Adults have been recorded on wing from late May to early June, probably in one generation per year.[http://www.nev.nl/tve/pdf/te0148225.pdf Japanese Elachista studied by Parenti (1983) (Lepidoptera, Elachistidae): The Subgenus Aphelosetia and the Gleichenella-, Tetragonella-, and Bifasciella-Groups]
