Bohemannia pulverosella (Stainton, 1849)
[Lepidoptera: Nepticulidae]

Dusty Apple Pigmy

Trifurcula pulverosella Stainton, 1849. Cat. Brit. Lep. Pterophoridae: 30
Bohemannia pulverosella
(Stainton, 1849).

Leaf-miner: The larvae create a distinctive blotch mine in the leaves of apple (Malus ). The larva cuts an exit hole on the underside of the leaf, which distuingishes the mine from that of Ectoedemia atricollis (UKMoths).

Egg either at upperside or underside of the leaf, close to the leaf margin. The mine begins as a narrow corridor which is strongly contorted, unless it lies close to the leaf margin. The corridor abruptly widens into an elongate blotch, that often runs over the initial corridor. The frass is brown; it almost fills the initial corridor; in the blotch it is concentrated in its first section. Pupation external; exit slit invariably in the lower epidermis. In Ectoedemia atricollis, of which the mine bears some resemblance to the one of pulverosella the exit slit is in the upper epidermis; moreover, atricollis is much later in the year (Bladmineerders van Europa).

The gallery leads to large brownish blotch (British leafminers).

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 yellow, head pale brown (British leafminers). Yellow (Emmet, 1983a); Gustafsson and van Nieukerken (1990a) give a description of the larva (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).
