Stigmella samiatella (Zeller, 1839)
[Lepidoptera: Nepticulidae]

Chestnut Pigmy


Lyonetia samiatella Zeller, 1839. Isis.: 215.
Stigmella samiatella
(Zeller, 1839).


Leaf-miner: The gallery is long and broad, frass dispersed in later part of mine (British leafminers).

Oviposition on the leaf underside, almost always close to a thick vein. Mine a fairly long, rather slender corridor. Frass in a broad, often interrupted central band; locally it may be in coiled (Bladmineerders van Europa).

It is recommended that you try to rear out the adults to be certain of their identity.

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 illustrated in 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 illustrated in UKMoths by Rob Edmunds. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
