Stigmella oxyacanthella (Stainton, 1854)
[Lepidoptera: Nepticulidae]

Common Fruit-tree Pigmy


Nepticula oxyacanthella Stainton, 1854
Stigmella oxyacanthella
(Stainton, 1854).


Leaf-miner: The reddish frass is linear, later in arcs, finally dispersed (British leafminers).

Long corridor, that widens only little, and winds freely through the leaf, not influenced by the venation. In thick, sun-exposed leaves the mine may be much shorter, especially in Cotoneaster, Malus and Pyrus. Frass brown, in arcs. (Bladmineerders van Europa).

The mine is also illustrated in UKMoths and 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).

The larva is green (British leafminers). The larva is illustrated in Bladmineerders van Europa.

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

The cocoon is illustrated in British leafminers.

Adult: The adult is illustrated in UKMoths. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
