narrow, white corridor, descending from close to the leaf tip to
the leaf base or even stem. Frass in an inconspicuous grey line.
From the stem the larva may enter a new leaf (Steuer, 1987a; Bland,
1996a) (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).
Lemon yellow; setae unusually long. Pronotum with two elongate brown
spots. also the anal plate has a brown marking. Prolegds with 2-4(5)
crochets in a faint, posteriorly concave, arc (Steuer, 1987a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Described by Patocka (1999a) and Patocka and Turcani (2005a)
(Bladmineerders van Europa).
The adult is illustrated in UKMoths.
The male and female genitalia are illustrated by the Lepidoptera Dissection
Festuca gigantea is treated
as Schedonorus gigantea (Giant Fescue) and Festuca
pratensis is treated as Schedonorus
pratensis (Meadow Fescue) by Stace (2010).
