Enteucha acetosae (Stainton, 1854)
[Lepidoptera: Nepticulidae]

Sorrel Pigmy


Nepticula acetosae Stainton, 1854. Ins. Brit. Lep. Tin. Pteroph.: 303.
Nepticula arifoliella
Klimesch, 1940. Zeits. Wien. ent. Ver. 25: 92.
Enteucha acetosae
(Stainton, 1854).


Leaf-miner: Oviposition at the leaf underside, usually near a vein. The mine is a narrow, hardly widening, corridor that makes about 5 whole of half circles closely around the egg. The leaf tissue around th mine is intensely reddened; often several mines in a leaf. Frass in a narrow central line. Pupation outside the mine (Bladmineerders van Europa).

The gallery starts in tight spirals, turning leaf red (British leafminers).

The larva moves away in an irregular gallery (UKMoths).

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).

Larva pale yellow (British leafminers). Body pale yellowish, head very pale light brown (Gustafsson and van Nieukerken, 199a) (Bladmineerders van Europa).

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

Pupation on detritus in a cocoon (British leafminers).

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