Elachista serricornis is a moth of the family Elachistidae found in Europe.
The wingspan is 7–8 millimetres (0.28–0.31 in).[1] The head is grey, face whitish. Forewings in male grey, in female blackish-grey ; plical stigma black, elongate, followed by a white dot ; an oblique white triangular costal spot at 2/3 ; a small indistinct whitish tornal spot somewhat beyond it. Hindwings grey.grey.[2]
The larvae feed on Carex elata, rare spring sedge (Carex ericetorum), Carex ferruginea, wood segge (Carex sylvatica), bladder sedge (Carex vesicaria), common cottongrass (Eriophorum angustifolium), Eriophorum latifolium, hare's-tail cottongrass (Eriophorum vaginatum) and Scirpus sylvaticus.[3] Young larvae make a long, brown corridor, and hibernate in this. In spring, the larva makes a new mine in another leaf, starting near the base of the blade. The mine widens upwards and forms a blotch at the end. Pupation takes place outside of the mine.[4]
It is found from Fennoscandia and northern Russia to northern Italy and from Ireland to Poland and Hungary.[5]
