Young larvae bore in the midrib, later they mine the leaf from
a web spun over of the leaf (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).
Grey green, with some vague reddish brown length lines; head and
prothoracic plate light brown; rear margin of the pronotum black
brown; anal plate grey green (Jansen, 1999a; Bland et al., 2002a;
Gómez de Aizpúrua, 2003a) (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, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
In the literature also recorded on Atriplex portulacoides,
Salicornia europaea, Suaeda maritima and Suaeda
vera. However, according to Maurice Jansen (in litt.) these
associations are very dubious (Bladmineerders van Europa).
