[Lepidoptera: Nepticulidae]

Ectoedemia rubivora
(Wocke, 1860).

Leaf-miner: A contorted gallery with dispersed frass, leading to a blotch (British leafminers).

Egg at the underside of the leaf. The mine is a highly contorted gallery, strongly widening towards the end. Frass in the second half of the gallery dispersed. The larva mines venter upwards. Mostly several mines in a leaf (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).

Larva greenish-white with green gut-line and brown head (British leafminers). The larva is also illustrated in Bladmineerders van Europa.
