Leaf-mine: A lower surface mine. Pupation normally in the ground (Spencer, 1976: 202).

Broad, usually lower-surface corridor in the blade, generally first rising, then descending. Mostly one larva in a mine, but sometimes several mines on a leaf may merge. Frass in grains that gradually become both larger and more widely spaced. Pupation outside the mine (Bladmineerders van Europa).

Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.

The yellow larva is described by de Meijere (1938), Nowakowski (1973) and (Dempewolf (2001: 119).

Posterior spiracles with a circle of 12-18 bulbs. Mandibles with 2 teeth each, strongly alternating. Above the mandibles a transverse row of fine hairs (Bladmineerders van Europa).

Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).

Yellowish-brown (Spencer, 1976: 202). Puparium yellow- to blackish brown (Bladmineerders van Europa).

Comments: Festuca gigantea is treated as Schedonorus gigantea (Giant Fescue) and Festuca pratensis is treated as Schedonorus pratensis (Meadow Fescue) by Stace (2010).
