Leaf-miner: The larval mine is a long gallery with linear black frass to
begin with, subsequently neatly scattered, and finally more central
and irregular. The egg is usually laid on the underside of the leaf
(UKMoths).
Forms a long, relatively wide mine. The frass is initially in a thin central line, but later may vary from a thin central line to frass almost filling the mine (British
leafminers).
Oviposition
at the underside of the leaf. The mine is a remarkably long, not
very slender corridor. Frass line of inconstant width, mostly occupying
more than half the width of the gallery (Bladmineerders van Europa).
It is recommended that you try to rear out the adults to be certain of their identity.
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).
Yellow,
head brown (Borkowski, 1972b; Gustafsson and van Nieukerken (1990a).
Abdomen 9 with two pairs of setae (other species, as far as known,
having three pairs) (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.
