Description

The wingspan is 9–10 millimetres (0.35–0.39 in). Adults are on wing from May to July. There are two generations per year.

Larvae have been recorded on bent (Agrostis species), sweet vernal grass (Anthoxanthum odoratum), sedge (Carex species), tufted hairgrass (Deschampsia cespitosa), fescue (Festuca species), Yorkshire fog (Holcus lanatus), reed canary grass (Phalaris arundinacea) and smooth meadow-grass (Poa pratensis), but tufted hairgrass is the main hostplant. The other host plants are not all equally trustworthy because of possible confusion with Elachista canapennella.[1]

The young larvae make a short corridor that is stuffed with frass in spring. After hibernation, they vacate this mine and make a number of elongated blotches, all descending from the leaf tip.

Distribution

It is found in most of Europe, except the Iberian Peninsula and the Balkan Peninsula.[2]
