Leaf-miner: Oviposition on a young shoot. The larva penetrates a leaf, empties
it, leaves it, often by making another hole in the epidermis, and
starts a new mine. Older larvae bore in a twig. Pupation external.
Mines twigs rurn brown and are dropped (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 of aurulentella has body green; head, prothoracic and anal plate black; feet greenish brown (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patočka and Turčáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths
and the Encyclopedia
of Life. The male
genitalia are illustrated by the Lepidoptera Dissection Group.
leylandii is treated as X
Cuprocyparis leylandii (Leyland Cypress) by Stace (2010).
Hosts in Great Britain & Ireland:
of year - larvae:
Mid June - end March (Bladmineerders van Europa).
of year - adults: May and June (UKMoths).
in Great Britain & Ireland: This tiny (6-8 mm wingspan),
but quite distinctive moth was not discovered in Britain until 1982,
when one was caught in London. More recently there have been several
more records and it is thought that these are being imported with
garden conifers, probably juniper and Leyland cypress etc. (UKMoths);
