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

Apple Pygmy


Nepticula malella Stainton, 1854. Ins. Brit. Lep. Tin. Pteroph.: 204.
Stigmella malella
(Stainton, 1854).


Leaf-miner: The gallery is sinuous, widening later, with linear frass (British leafminers).

Egg at the underside of the leaf, near a vein. The mine is quite variable. It is a rather strongly tortuous corriodor, sometime widening only a little, sometimes strongly, at times ending in a secondary blotch. Frass black or brown, in a narrow central line (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, head brown (British leafminers; Briolini (1961a); Gustafsson and van Nieukerken (1990a); 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).
