Trifurcula cryptella (Stainton, 1856)
[Lepidoptera: Nepticulidae]

Wood Lotus Pigmy


Nepticula cryptella Stainton, 1856. Entomol. Ann.: ?
Trifurcula cryptella
(Stainton, 1856).


Leaf-miner: An initial gallery, which usually follows the leaf margin. Then forms a blotch, mining from the leaf base to the tip. The presence of a pupa in the mine is unusual for this species and may indicate parasitism (British leafminers).

Oviposition on the leaf underside. The mine begins as a long corridor with a very broad, green frass line. This corridor suddenly widens into a broad blotch, that in the end may occupy almost an entire leaflet. The blotch generally begins in the leaf base, and it is here that most frass is concentrated. Shortly before pupation the larva leaves its mine through an exit slit in the lower epidermis. After the mine has been vacated the leaflet drops off (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).

The larva is pale yellow, with a pale brown head (British leafminers).

The larva is pale yellow, looks green in the mine; it lies dorsum upwards. The larva is described by Johansson et al. (1990a); thorax dorsally with 13, 11, and 9 pairs of setae per segment, respectively (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).
