Leaf-mine:
The first instar larva tends to make a U-shaped mine, whereas later
larvae make irregular mines. Final instar larvae spin the leaves
together and feed in a silken tube amongst the seeds (British
leafminers). The mine is also illustrated in UKMoths
and Nederlandse
bladmineerders.
Larva:
The larva is illustrated in British
leafminers, UKMoths
and Nederlandse
bladmineerders.
Pupa:
In
a cocoon of sand grains and detritus (British
leafminers).

Hosts
elsewhere:
Time
of year - mines: September - October (British
leafminers).
Time
of year - adults: July and August (UKMoths).
Distribution
in Britain: One of the commonest gelechid moths on saltings
in the British Isles (UKMoths)
including East Ross, Forfar, Kincardine, North Essex, North Somerset,
South Hants, South Wilts, Surrey (NBN
Gateway distribution map - BRERC,
HBRG, JNCC,
NE
and NESBRC)
and Northern Ireland (Karsholt & van Nieukerken in Fauna
Europaea). It
can easily be confused with several other Scrobipalpa species,
so examination of the genitalia is usually necessary, though even
then they can be difficult to determine (UKMoths).

leafminers distribution map.
Also
recorded in the Republic of Ireland (Karsholt & van Nieukerken
in Fauna
Europaea).
Distribution
elsewhere: Widespread in Europe including Austria, Belgium,
Czech Republic, Danish mainland, Estonia, Finland, French mainland,
Germany, Hungary, Latvia, Norwegian mainland, Poland, Romania, Russia
- South, Slovakia, Spanish mainland, Sweden, The Netherlands and
Ukraine (Karsholt & van Nieukerken in Fauna
Europaea).
