Caloptilia cuculipennella (Hübner, 1796)
[Lepidoptera: Gracillariidae]

Feathered Slender


Tinea cuculipennella Hübner, 1796. Samml. Europ. Schmett. 8 (Tin.): 6A fig. 1, 6B fig. 2
Caloptilia cuculipennella
(Hübner, 1796).


Leaf-miner: Initially an epidermal mine on the upper surface of the leaf, later the mine starts to contract and the leaf concealing the mine. Now the larvae leave the mine and live freely in a downwards rolled leaflet (Catalogue of Belgian Lepidoptera).

Larva solitary in an elongate upper-surface epidermal (thence silvery) mine. Frass initially in a rust-coloured central line. Later, when the mine starts to contract and the leaf folds over the mine, the frass is black and concentrated in a corner of the mine. At this point the larva leaves the mine, and starts living freely in a downwards rolled leaflet (Bladmineerders van Europa).

The mine can be distinguished from that of G.syringella on the same plant as it is a silver colour whereas that of G.syringella is brownish (British leafminers).

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).

Emmet, Watkins and Wilson (1985a) write that the larva has a black spot laterally on head and prothorax; that does not match with the photo above (Bladmineerders van Europa).

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

Pupation in a flimsy white cocoon, attached hammock-wise within the final cone (Catalalogue of Belgian Lepidoptera). Pupation in a white cocoon that is attached to the leaf with fine threads (Bladmineerders van Europa).

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