Elachista compsa is a moth of the family Elachistidae. It is found from Fennoscandia and the Baltic region to Germany, Poland to Italy.
The wingspan is 8–11 millimetres (0.31–0.43 in).[2]
The larvae feed on Deschampsia cespitosa and Melica nutans uniflora. They mine the leaves of their host plant.[3] Larvae can be found from October to December. They then overwinter within the mine. In spring, they vacate the mine to pupate. There is a second generation in July. They have a light brown head.
