Wingspan c. 10mm.
This is a quite common species throughout most of the British Isles, inhabiting a range of grassland habitats. Named after the noticeably whitish forehead, the most likely confusion species is E. apicipunctella, which however has an additional white spot in the apical area of the forewing.
During September until around May, the larva mines a blade of a variety of grasses, leading to a pale blotch, sometimes moving between blades.
The adults fly in a single generation during June and July.
