flat, whitish, relatively broad corridor descending from the leaf
tip. Frass irregularly scattered. The larva may make several mines
during its lifetime. Pupation outside the mine (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
Yellowish grey, head and protharacic shield black; prothoracic shield
divided (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
The adult is illustrated in UKMoths.
genitalia are illustrated as Cosmiotes freyerella by the
Lepidoptera Dissection Group.
Festuca arundinacea is treated
as Schedonorus arundinacea (Tall Fescue) by Stace (2010).
Hosts in Great Britain & Ireland:
of year - larvae: The larval mines can be found from March to
