Stigmella basiguttella (Heinemann, 1862)
[Lepidoptera: Nepticulidae]

Base-spotted Pigmy


Nepticula basiguttella Heinemann, 1862. Schmett. Deutschl. 2 (1): 199.
Stigmella cerricolella
Klimesch, 1946. Z. Wien. ent. Ges. 31: 160, fig'd.
Stigmella basiguttella
(Heinemann, 1862).


Leaf-miner: The gallery is long and sinuous, filled with greenish frass. The initial mine is greenish/brown and becomes more visible as it ages and goes browner (British leafminers).

Ovipostion close to a thick vein, mostly at the upper side. The mine is a long, slowly widening, slender corridor, with a characteristic sinuous course. Frass completely filling the corridor, in clear arcs, green when fresh, brown later. Fresh mines are almost concolorous with the leaf, and not very apparent (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 is green (British leafminers and 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).
