Leaf-mine:
Long, extremely narrow lower- or upper-surface corridor, with
a black or brown central frass line. After a while this primary
mine is vacated, and the larva starts making shorter, much broader,
full depth blotch mines. In the end the larva lives free among spun
leaves (Bladmineerders
van Europa).
The
mine is also described and illustrated in UKMoths.
Larva:
The larvae can live on plants on the lowest parts of saltings, which
are frequently immersed by the tide (UKMoths).
Dirty
yellow with a red length line; head light brown; pronotum, anal
shield and thoracic feet black (Bladmineerders
van Europa).
Pupa:
The pupa is described and illustrated in UKMoths.
Adult:
The adult is illustrated in UKMoths.
The female
genitalia, but not the male genitalia (check
for update), are illustrated by the Lepidoptera Dissection Group.
Comments:
According to the literature also on Aster tripolium and Suaeda
maritima, but probably this concerns occasional observations
or confusion with the mines of Bucculatrix maritima (Bland,
2002a; Jansen, in litt.)
The
list of hostplants presented by Elsner et al. (1999a), including
Atriplex, Spergularia media and even Ferula is bizarre
(Bladmineerders
van Europa).

Time
of year - larvae: May (UKMoths).
Time

Distribution
in Great Britain & Ireland: Found on saltings in England
and Wales where its foodplants grow (UKMoths)
including Dorset, East Kent, Isle of Wight, North Lincoln, South
Essex, South Hants and West Sussex (NBN
Gateway distribution map - NE).
It is regarded as a local and difficult-to-record species (MBGBI
4-2), and can probably be most easily found by searching for larvae
from late April to early June (UKMoths).
