Leaf-miner: The
frass is arranged in a spiral and a circular blotch is formed (British
leafminers).
Egg
at the underside of the leaf. The mine is an upper-surface blotch
without anything like a preceding corridor. The blotch is about
circular, but my have broad lobes. Black frass grains lie in indistinct
arcs or spirals, glued to the upper epidermis, and forming a cark
central patch. The larva can leave a mined leaf, and restart elsewhere.
Pupation external (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).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).Described by Patocka (2000a) and Patocka and Turcani (2005a)
(Bladmineerders van Europa). Cocoon
spun beneath the leaf (British
leafminers).
Adult:
The adult is not illustrated in UKMoths (check for update). The species is included in mothdissection.co.uk.
