Cnephasia incertana (Treitschke, 1835)
[Lepidoptera: Tortricidae]

Light Grey Tortrix


Sciaphila incertana Treitschke, 1835. Schmett. Europ. 10 (3): 91.
Cnephasia incertana
(Treitschke, 1835).


Leaf-miner: In the first instar the larva mines the leaves, forming short, irregular, blotch-like mines, but in later instars it lives externally, feeding in spun leaves and often twisting those of tender shoots (Bradley et al., 1973).

Small, full depth mine without a definite shape; little frass. Some silk is deposited in the mine. The larva soon leaves the mine and continues feeding among spun leaves (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).

Head light-brown or yellowish brown, edged with black postero-laterally, ocellar area blackish; prothoracic plate black edged with whitish anteriorly; abdomen dull dark green; pinacula distinct, black, sometimes brownish but with black bases to setae; anal plate large, black (Bradley et al., 1973). The overwintering larvae feed in a spinning on a range of herbaceous plants (UKMoths).

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

Dull black; spines on the cremaster not bent into hooks, short, their lenght less than the distance to a ridge lying ventrad; caudal bristles only slightly thickened away from their point of origin, bent distally to form hooks (Bradley et al., 1973).

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

Comments: Ranunculus ficaria is treated as Ficaria verna (Lesser Celandine) by Stace (2010).
