This moth has a wingspan of 9–12 mm. It can be confused with species from other families, but O. salaciella is fairly easy to distinguish from other small species due to the typical scales at the top of the eyes, the so-called eye-caps. It also misses the brown dot on the forewing present with P. auritella.
