Leaf-miner: The larvae form galleries along the edge of the leaf, leading to the development of large blotches on the leaf margin (UKMoths). Oviposition on the leaf underside. There begins a full depth corridor that gradually widens into an irregular elliptic blotch. Generally the corridor part for a large stretch follows the leaf margin. If oviposition occurred well away from the leaf margin, the corridor starts by making some irregular loops around the oviposition site; however, when, as often occurs, the egg is placed close to the leaf margin, at once the leaf margin is mined. Frass blackish brown (rarely brown) in the corridor, black in the blotch. In the corridor the frass lies in lumps or indistinct coils; in the blotch the frass is irregularly dispersed. Pupation outside the mine; exit slit in the upper epidermis, contrary to Bohemannia pulverosella, with which atricollis may co-occur on Apple (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). Larva whitish, head and ventral spots dark (this distinguishes it from Stigmella hybnerella, which has a pale head) (British leafminers). The larva is greenish white and lies belly-up in the mine. The head is blackish brown (contrary to the pale brown head of Stigmella hybnerella, of which the mines sometimes resemble those of atricollis). Young larvae, in their 2nd and 3rd instar, with a chain of black ventral plates (van Nieukerken, 1985a). 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 species is included in mothdissection.co.uk.
