Leaf-mine: Larva forms a long greenish linear mine, frequently following a
vein; mines can be up to 10 cm long. Pupation internal; anterior
spiracles projecting through the leaf epidermis (Spencer, 1972b).
with the frass in an almost uninterrupted line along one side. In
small leaves the corridor often follows the margin, but when space
is not limited, like in Hart's-tongue Fern, it curves smoothly,
not infrequently running over the midrib for some distance. Pupation
mostly within the mine; the anterior spiracles then penetrate the
epidermis (Bladmineerders van Europa).
Forms a long narrow mine (up to 10cms). It is normally greenish and upper surface (British
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 larva is described by Dempewolf (2001:
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).
'Slipper-shaped', whitish-yellow with minute black spiracles; posterior
spiracles each with an ellipse of 9 bulbs.
Ceterach officinarum is treated as Asplenium
ceterach (Rustyback) and Phyllitis
scolopendrium is treated as Asplenium
scolopendrium (Hart's-tongue) by Stace (2010).
Hosts in Great Britain & Ireland: Asplenium ruta-muraria (Wall-rue), Phyllitis scolopendrium (= Asplenium scolopendrium)(Hartstongue), Polypodium vulgare (Common Polypody)
of year - mines: May-September.
of year - adults: May.
