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

Small Beech Pigmy


Nepticula tityrella Stainton, 1854. Ins. Brit.: 304.
Stigmella tityrella
(Stainton, 1854).


Leaf-miner: A gallery completely without coiled frass (British leafminers).

Ovipisition at the underside of the leaf, in the axil of a vein. From there a corridor, that does not widen much, zigzags between two lateral veins in the direction of the leaf margin. Frass at first in a narrow central line. Later the frass becomes widely dispersed; it never lies in coils (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 yellow, dark head and prothoracic plate (British leafminers). The larva is also illustrated in 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. The species is included in mothdissection.co.uk.
