Leaf-miner: A mine with several creases in lower epidermis, causing the
leaf to arch or fold over (British
larvae feed on blackthorn or sometimes wild plum. On blackthorn
the mines are narrow and cause the leaf to pucker strongly, often
folding right over, and being whitish, resemble those of the blackthorn-feeding Parornix species (UKMoths).
strongly inflated tentifom mine bewtwwn to side veins. Lower epidermis
with folds, green. Pupa in a white cocoon, frass in a mass in a
corner of the mine. Before emergence the pupa works itself halfway
out of the mine (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).
The pupa is illustrated in Bladmineerders van Europa.
The adult is illustrated in UKMoths.
