Cnephasia conspersana Douglas, 1846
[Lepidoptera: Tortricidae]

Coast Shade


Cnephasia conspersana Douglas, 1846. Zool. 9: 1267.


Seed/Shoot feeder: Larva feeds in the flower heads of composites and other plants drawing together the petals to form a shelter and eating out the immature seeds; also on young shoots drawing together the terminal leaves and eating out the heart (Bradley et al., 1973).

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 and prothoracic plate light brown or yellowish brown, head with a black lateral marking; abdomen light yellow, sometimes pale greenish grey dorsally, translucent; pinacula small, black; peritreme of spiracles black; anal plate yelowish brown, marked with black; anal comb black; thoracic legs yellowish; terminal segments brownish (Bradley et al., 1973).

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

Blackish brown (Bradley et al., 1973).

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