Elachista biatomella is a moth of the Elachistidae family. It is found from Sweden to the Iberian peninsula, Sardinia and Italy and from Great Britain to Ukraine.
The wingspan is 7-9 mm.[2] Adults are on wing from May to September in two generations per year.[3]
The larvae feed on Carex acuta prolixa and Carex flacca. They mine the leaves of their host plant. The mine starts at a leaf axil and ascends as a narrow corridor with a thin frass line. After 20-30 mm, the direction of the mine reverses, resulting in an elongate and lightly inflated blotch. Pupation takes place outside of the mine.[4] Larvae can be found from June to July and again (after overwintering within the mine) from September to April. They are yellowish with a dark brown head.
