Pseudoswammerdamia combinella (Hübner, 1786)
[Lepidoptera: Yponomeutidae]

Copper-tipped Ermel

Tinea combinella Hübner, 1786. Beitr. Ges. Schmett. 1 (1): 5.
Pseudoswammerdamia combinella
(Hübner, 1786).

Leaf-miner: The small larvae leaf-mining at first, and later living externaly in a silken web (UKMoths).

The young larva makes a full depth blotch. Most frass is ejected by a slit in the epidermis. Later the larva life free in a web, often communally (Agassiz, 1996a) (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 yellowish, dorsal line yellowish green, a subdorsal line of dull red dots. Head pale yellowish (Agassiz, 1996a) (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).

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
