larva creates a long narrow mine in the blade (UKMoths).
fairly translucent. It starts as a narrow corridor, running towards
the leaf tip, but this almost invariably is overrun be a later,
broad, descending corridor. The centre of the mine contains a vertical
tube made of loose silk, in which the larva can quickly move up
or down, and in which also most frass gets trapped. The sides of
the mine are smooth (contrary to E.
gangabella ). Mines are difficult to find, because the leaves
are wilting when larvae are present (Bladmineerders van Europa).
Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).
Dark olive green (greyish black while hibernating). Head and prothoracic
plate black. Each thorax segment dorsally with a pair of roundish
or crescent shaped light spots (Steuer, 1973a) (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Hosts in Great Britain & Ireland:
of year - larvae:
Larvae in autumn; in October they are full grown, but they leave
their mine only just before pupation, in early spring (Bladmineerders van Europa).
of year - adults: The adults tend to fly during June (UKMoths).
in Great Britain & Ireland: Widely distributed on moors
and heaths over much of Britain (UKMoths)
including Caernarvonshire (VC49), Glamorganshire (VC41), Merionethshire (VC48), Monmouthshire (VC35),
North Ebudes (VC104), Pembrokeshire (VC45), Shropshire (VC40), South Wiltshire (VC8), Stafford
