[Lepidoptera: Cosmopterigidae]

Vivid Cosmet

Cosmopterix schmidiella Frey, 1856. Tin. Schweiz.: 257.

Leaf-miner: Large blotch, that may occupy an entire leaflet. During feeding pauses the larva rests in a silken resting place above the midrib, and is well hidden then. Pupation outside the mine (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).

Head brown, mouthparts darker. Body (and thoracic feet) pale orange-yellow, purple dotted length lines dorsally and laterally. Prothoracic plate black, divided (Koster, 2002c) (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 not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
