Elachista bedellella is a moth of the Elachistidae family. It is found from Scandinavia to the Iberian Peninsula, Italy and Bulgaria and from Great Britain to Russia.
The wingspan is 7–8 millimetres (0.28–0.31 in). Adults are on wing from May to June and again in August in two generations per year.
The larvae feed on Arrhenatherum elatius, Avena, Avenula pratensis, Festuca ovina, Phleum, Poa nemoralis and Poa trivialis. They mine the leaves of their host plant. The mine has the form of a blotch in the leaf tip. A single larva may mine two to three leaves. Larvae can be found from September to the end of April and again (after overwintering within the mine) from June to July. Young larvae are yellowish white with a light brown head, while the body becomes grey green when they are full-grown.
