Leaf-mine:
Initially the larva mines a basal leaf, subsequently feeding
in flower buds (which turn yellow), opened flowers and foliage (UKMoths).
Larva:
The
camouflaged larvae vary from green to brownish yellow (UKMoths).
Pupa:
The
slender green or red pupa is attached to the foodplant (UKMoths).
Hosts
in Britain:
Hosts
elsewhere:
Time
of year - mines: Two or more generations from June to October
or later. It is uncertain which stage (s) overwinter (UKMoths).
Time
of year - adults: The adult can be found from July to September
in two or more overlapping broods. It generally flies from dusk
onwards, but it can be disturbed from low herbage in the daytime.
It can easily be mistaken for a faded specimen of the common Stenoptilia
bipunctidactyla (agg.), so moths taken near large amounts of
the foodplants should be examined closely (UKMoths).
Distribution
in Britain: Widely distributed in southern Britain (UKMoths)
including East Kent, Hereford, North Essex, North Lincoln, South
Devon, South Lancaster and South Lincoln (NBN
Gateway distribution map - BRERC,
JNCC, NE
and SHWRG).
Usually
locally restricted to sparsely vegetated habitats, such as sea-cliffs,
sand hills, old sand and gravel workings and chalky or dry pastures,
where its foodplants grow in quantity and the moth may be abundant
(UKMoths)
Distribution
elsewhere: Widespread in Europe including Albania, Andorra,
Austria, Azores, Belgium, Bosnia and Herzegovina, Bulgaria, Corsica,
Croatia, Cyprus, Czech Republic, Danish mainland, Finland, French
mainland, Germany, Gibraltar, Greek mainland, Hungary, Italian mainland,
Luxembourg, Macedonia, Malta, North Aegean Is., Poland, Portuguese
mainland, Romania, Sardinia, Sicily, Slovakia, Slovenia, Spanish
mainland, Sweden, Switzerland, The Netherlands and Yugoslavia (Karsholt
& van Nieukerken in Fauna
Europaea).
