Leaf-miner: The first half of the mine is filled with brown frass and the
early gallery is broad. The frass is later coiled and the larva
is yellow. S.
crataegella has a thinner initial gallery. Mines starting
in the petiole are harder to name without seeing the larva (British
leafminers).
Oviposition
on the underside of the leaf, rarely on the petiole (in Scandinavia
the reverse is true, see Johansson et al., 1990a). The mine is a
corridor that quickly widens into a secondary blotch without, ar
only a very short, free initial corridor part. The mine is constrained
between two veins or, less frequently, a lateral vein and the leaf
margin. In the pseudoblotch the frass is warm brown and coiled (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).
Yellow (British
leafminers; Emmet, 1983a; Gustafsson and van Nieukerken, 1990a;
Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
Adult:
The adult is illustrated in UKMoths by Rob Edmunds.
The species is included in mothdissection.co.uk.
Comments:
Skala (1939a) found the mine once also on Prunus domestica.
He also mentions the species from Hippophae; the latter association
has also been reported by Szocs (1977a) (Bladmineerders van Europa).
