larvae make small, brown, full depth blotch mines without frass
in the young leaves, from within the protection of a spinning. Later
they cause upper-surface window feeding, while hidden among spun
leaves (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).
Body dull brownish green, five purplish-brown length lines; second
thoracic segment dark purplish-brown; pinnacula small, black; prolegs
concolorous with body. Head, prothoracic and anal plates, and thoracic
legs black (Heckford, 1955a). Jansen (199a) adds that some larvae
have a brown, rather than green body (Bladmineerders van Europa).
Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).
See Patocka and Turcáni (2005a) (Bladmineerders van Europa).
The adult is illustrated in UKMoths.
The male and female genitalia are illustrated by the Lepidoptera Dissection
Possibly also Mentha. References to Achillea, Artemisia
campestris, Centaurea panicalta, C. stoebe (Acosta rhenana)
and Thymus serpyllum are incorrect, probably partly caused
by confusion with Scrobipalpula psilella (Bladmineerders van Europa).
