Tinea semifulvella is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the nominate subfamily Tineinae. It is widespread and common in much of the western Palearctic, but seems to be absent from Portugal and the Balkans as well as the outlying islands. The nocturnal adults are on the wing around May to September, depending on the location, and are easily attracted to light sources.
