Elachista biatomella is a moth of the family Elachistidae found in Europe.
Description
The wingspan is 7–9 millimetres (0.28–0.35 in). [1] The head is pale grey, face whitish.Forewings are ochreous - whitish, irrorated with grey ; plical and second discal stigmata elongate, black, plical preceded and followed by whitish marks ; in darker specimens an oblique triangular white spot is visible on costa at 2/3, in paler specimens it is obsolete. Hindwings are grey.The larva is yellowish ; head brown ; 2 with two pale brown spots. [2]
Adults are on wing from May to September in two generations per year.
The larvae feed on acute sedge ( Carex acuta prolixa) and glaucous sedge ( Carex flacca), mining 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 millimetres (0.79–1.18 in), the direction of the mine reverses, resulting in an elongate and lightly inflated blotch. Pupation takes place outside of the mine. [3] 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.
Distribution
It is found from Sweden to the Iberian peninsula, Sardinia and Italy, and from Great Britain and Ireland to Ukraine. [4]
