Leaf-mine: A blotch with large dark grey larva - discarded grey larval
skin visible in vacated mine. The mine starts by the edge of the
leaf (British
leafminers).
Large,
white, primary, full depth blotch, following upon a very short corridor.
The blotch begins adjacent to the leaf margin, expanding deeper
into the leaf. Frass in striking, long threads. Pupation in the
soil. Vacated mines shrivel and wither away; later in summer no
a trace remains (Bladmineerders
van Europa).
Larva:
Dark grey and quite distinctive if the mined leaf is held up to
the light (UKMoths).
The
larva is also illustrated in Bladmineerders
van Europa.
Pupa:
Details unknown.
Adult:
The adult is illustrated in UKMoths.
The male
and female
genitalia are illustrated by the Lepidoptera Dissection Group.

Distribution
in Great Britain and Ireland: Although stated in the literature
as local in Britain (MBGBI), renewed interest in this group in recent
years has shown the species to be well distributed and quite common,
especially in northern England (UKMoths)
including Banff, Bedfordshire, Buckinghamshire, Derbyshire, East
Suffolk, Glamorgan, Herefordshire, Kincardine, North Aberdeen, North
Somerset, Northamptonshire, Shropshire, South Aberdeen, South Hampshire,
South Lancaster, South Wiltshire, Stafford, Surrey, West Gloucestershire,
West Kent, West Norfolk, West Suffolk, Westmorland and Worcestershire
(NBN
Gateway - N.B. includes Watsonian Vice Counties having publicly available records
that fall within or overlap the vice county border at 10km resolution
or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below). See also British
leafminers distribution map.

Distribution
elsewhere: Widespread in continental Europe including Austria,
Czech Republic, Danish mainland, Estonia, Finland, French mainland,
Germany, Latvia, Norwegian mainland, Poland, Romania, Russia - North,
Sweden, Switzerland and The Netherlands (Karsholt and van Nieukerken
in Fauna
Europaea).
