Povolnya leucapennella (Stephens, 1835)
[
Lepidoptera: Gracillariidae]


Gracillaria leucapennella Stephens, 1835. Ill. Brit. Ent. Haust. 4: 368.
Coriscium citrinellum
Zeller, 1839.
Caloptilia leucapennella
(Stephens, 1835)
Povolnya leucapennella
(Stephens, 1835).


Leaf-miner: Initially makes an oval blotch, between the veins. It then makes a small fold at the leaf edge; then two cones, formed by curling the leaf downwards (British leafminers, as Caloptilia leucapennella).

The mine begins as a narrow lower-surface epidermal gallery, that widens into an oval, eventually full depth blotch between two side veins. Later the larva lives free, at first in a folded leaf margin, finally in a partly rolled leaf tip. Possibly a preference for young leaves (Meyrick, cited by Emmet et al., 1985a) (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 greyish white, head brownish (Bladmineerders van Europa).

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

At the underside of the leaf, in a fold, under a greyish green membrane (Bladmineerders van Europa).

Adult: The adult is not illustrated in UKMoths (check for update). The male and female genitalia are illustrated by the Lepidoptera Dissection Group as Caloptilia leucapennella.
