Stigmella aceris (Frey, 1857)
[Lepidoptera: Nepticulidae]

Scarce Maple Pigmy


Nepticula aceris Frey, 1857. Linn. Ent. 2: 386.
Stigmella aceris
(Frey, 1857).


Leaf-miner: A gallery filled with green frass. In the older gallery the frass turns brown (British leafminers).

A narrow corridor. The coiled frass is greenish (blackish brown in old or dried mines). Generally the entire width of the corridor is filled up, making the mine rather inconspicuous. The sides of the corridor are not straight, rather irregular (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).

Bright green; see Gustafsson and van Nieukerken (1990a) and Schoorl et. al. (1985a) for an extensive description (Bladmineerders van Europa). The larva is green (British leafminers).

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 male genitalia, but not the female genitalia (check for update), are not illustrated by the Lepidoptera Dissection Group.
