Paraswammerdamia albicapitella (Scharfenberg, 1805)
[Lepidoptera: Yponomeutidae]

White-headed Ermel

Paraswammerdamia albicapitella
(Scharfenberg, 1805).


Leaf-miner: The short full depth corridor mine is made in the leaf in September and the larva then hibernates on the axil of the leaf, making a web and feeding the next spring (British leafminers). In the spring they feed on the leaves from within a silk web (UKMoths).

The larvae make a small full depth corridor in autumn. They pass the winter in a hiberaculum outside the mine, later they live free in a spinning (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).

Free-living larva- Body slender, reddish brown; head light brown; prothoracic plate dark brown. Laterally a bright white, broad but to the rear quickly narrowing length line on thorax of foremost abdomen segments. A similar dorsal line, but narrower and shorter, begins behind the head (Bladmineerders van Europa).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

Pupation on a twig in a cocoon (British leafminers).

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