Elachista tetragonella is a moth of the Elachistidae family. It is found from Fennoscandia to Spain and Italy and from France to Bulgaria.

A sprig of *Carex montana* exhibiting a mined leaf blade

The wingspan is 6–7 millimetres (0.24–0.28 in). Adults are on wing in January and again in June.^[2]

The larvae feed on Carex montana. They mine the leaves of their host plant. The mine has the form of a white elongate gallery in the top region of the leaf. The frass is deposited irregularly. Pupation takes place outside of the mine.^[3] They are dirty yellow with a pair of grey dorsal length lines and a yellowish head. Larvae can be found from April to the end of May.
