Stigmella roborella (Johansson, 1971)
[Lepidoptera: Nepticulidae]

Common Oak Pigmy


Nepticula roborella Johansson, 1971. Ent. scand. 2: 258, fig'd.
Stigmella roborella
(Johansson, 1971).


Leaf-miner: The first generation gallery is short, the second generation is longer. The frass is in a narrow line (British leafminers).

Egg at he upper- or underside. The mine is a long, slender, not very contorted corridor. In the first part the frass lies in a very narrow line; later the frass may in rare cases lie more widely scattered, but nowhere does it take more than 1/3 of the width of the gallery (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).

The larva whitish-yellow, head pale brown (this distinguishes it from S. atricapitella which has a dark head) (British leafminers).

Yellow, head light brown (Huisman et al., 2001; Johansson et al., 1990a). The light coloured head distinguishes the larva from the one of atricapitella (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 by Rob Edmunds. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
