Stigmella prunetorum (Stainton, 1855)
[Lepidoptera: Nepticulidae]

Scarce Sloe Pigmy


Nepticula prunetorum Stainton, 1855. Entomol. Ann.: 50.
Stigmella prunetorum
(Stainton, 1855).


Leaf-miner: A contorted gallery filled with green frass (British leafminers).

Egg at the underside of the leaf, often close to a vein. The mine is a corridor, running in several half or whole circles around the oviposition site. Only the last segment breaks loose, and often runs along the leaf margin. The frass is greenish, lying in coils that are so wide as to almost completely fill the corridor (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 green (British leafminers). Bottle green. The larva is described by 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).

Comments: In the older literature also Crataegus and even Mespilus are mentioned [as hosts]. This is surprising, because the mines are so unmistakable (Bladmineerders van Europa).
