Epinotia fraternana (Haworth, 1811)
[Lepidoptera: Tortricidae]

Silver-barred Bell


Tortrix fraternana Haworth, 1811. Lep. Brit.: 449.
Epinotia fraternana
(Haworth, 1811).


Leaf-miner: Egg generally at the upperside of the tip of a needle. The larva spins a number of needles together in a more or less conical spinning, then mines out one needle after the other. The larva enters and leaves a needle through the same opening, mostly in the distal half of the needle. Most frass is ejected, part of it is trapped in the spinning. During feeding the larva pauses to rest in the mine. Most mines in the older needles. Pupation external (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 light green; head, pronotum and anal plate light brown; anal comb present, brown, with 4-7 prongs; thoracic legs green; pinacula brown (Bradley et al., 1979a; Patocka, 1960a) (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 illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
