Leaf-miner: The mine is upper side and silvery, over the midrib. Leaf later
may fold upwards, concealing the mine (British
is on the base of the midrib. From there an epidermal corridor is
made, running towards the leaf tip. The corridor then is widened
into an epidermal, silvery blotch, finally into a longitudinally
contracted tentiform mine. Frass in fine, shining grains, mostly
in a line over the midrib, rarely in a mass in a corner of the mine.
The epidermis of the mine has a number of yellow spots, but never
the black specks that are apparent in P.
corylifoliella (Bladmineerders van Europa).
mine is also illustrated in UKMoths, on the Royal Horticultural Society's website and on iSpot.
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).
The larva is illustrated in Bladmineerders van Europa.
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
pupa is illustrated in Bladmineerders van Europa.
The adult is illustrated in UKMoths.
genitalia are illustrated by the Lepidoptera Dissection Group.
When population densities become high in summer also other Rosaceae
may be infested, like Chaenomeles; Cotoneaster lucidus; Crataegus;
Cydonia oblonga; Malus; Pyracantha coccinea; Pyrus; Sorbus torminalis.
Because only Pyracantha keeps its foliage in winter, and
leucographella larvae do not have a diapause, this is their
normal home base (Sefrová. 1999a; Triberti, 2007a) (Bladmineerders van Europa).
Hosts in Great Britain & Ireland:
of year - larvae: July, October - April. The larva in the autumn

of year - adults: Having a number of generations, the adults
can be found between April and October (UKMoths).
in Great Britain & Ireland: Discovered in Essex in 1989,
this species has spread rapidly northwards through England to parts
of north York, and is now fairly common in gardens and other suburban

Derbyshire (VC57), East Norfolk (VC27), East Suffolk (VC25), East Sussex (VC14), Glamorganshire (VC41),

been recorded from Cheshire and Huntingdonshire (British
leafminers - Newsletter, October 2008) and Derbyshire (VC57), (British
leafminers) See also British
leafminers distribution map.
