Leaf-miner
and case-bearer: The larva feeds on rose, building successively larger portable cases
from cut-out leaf fragments; September 3mm, October to April 6mm.
In mid-April the third and final, 6 or 7 mm, case is formed. At
first it is spatulate with a bivalved anal opening and serrate dorsal
keel formed from a leaf margin. During May, the case is expanded
dorsally, becoming cylindrical with a trivalved anal opening. The
expansion may conceal the dorsal serration (UKMoths).
The
leaf damage and case are also illustrated in British
leafminers.
The
larvae, which hatch around the end of August make three cases during
their lifetime. The final one, which they occupy after the hibernation,
is a laterally flattened tubular leaf case with a dorsal toothed
keel (remnant of the leaf margin from which the cases was excised).
Mouth angle about 60° (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).
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).
Adult:
The adult is illustrated in UKMoths.
The species is included in mothdissection.co.uk.

elsewhere:
Time
of year - larvae: Late August to late October, then April to
mid May.
Time
of year - adults: The adult occurs in late June - July, flying
at dusk and early morning; males will assemble to an unmated female
until 9 a.m. It can also be attracted to light at night (UKMoths).
