Seed-feeder:
The larva can be found on Juncus maritimus seedheads, both
standing and prone on the ground. The larval case, made from a hollowed
seed of the foodplant, is well camouflaged and easily overlooked.
Records should not be made purely on the basis of feeding holes,
as C. glaucicolella,
another species often abundant on saltings, makes similar holes
in Juncus maritimus. Care is needed in the identification
of the foodplant, especially when dealing with dead seedheads, as
the similar Juncus gerardii supports larvae of C. adjunctella
feeding on seeds in the same manner (UKMoths).
Larva:
Details unknown.

Hosts
elsewhere: Unknown.
Time
of year - larvae: September to May (UKMoths
& British
leafminers).
Time
of year - adults: The adult flies from late June to early August
at night and at sunrise. It comes to light, sometimes at a distance
from the coast (UKMoths).
Distribution
in Britain: This species is widespread on English and Welsh
coastal saltings where Sea rush (Juncus maritimus) grows.
It has also been recorded on the Firth of Forth (UKMoths),
South Gloucester (NBN
Gateway distribution map - BRERC)
and Northern Ireland (Karsholt & van Nieukerken in Fauna
Europaea).

recorded in the Republic of Ireland (Karsholt & van Nieukerken

Europaea).
Distribution
elsewhere: Widespread in Europe including Albania, Bulgaria,
Crete, Croatia, Cyprus, Danish mainland, French mainland, Greek
mainland, Italian mainland, North Aegean Is., Portuguese mainland,
Sardinia, Sicily, Spanish mainland, Sweden and The Netherlands.
