and case-bearer: Larva in autumn forming a few small mines.
Feeding restarts in the same case in spring before changing to a
new case by late April. In spring the cases or mines cannot be reliably
separated from those of C.
coracipennella or C.
larva lives two years. In the first year, in autumn, a composite
leaf case is made that resembles a boomerang: front and rear end
stand at almost right angles. In its second year the larva makes
a trivalved tubular leaf case of about 6 mm, with a mouth angle
of c. 45°; the case tapers somewhat to both ends (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 adult is illustrated in UKMoths and the Encyclopedia
of Life. The male
genitalia are illustrated by the Lepidoptera Dissection Group.
