Stigmella minusculella (Herrich-Schäffer, 1855)
[Lepidoptera: Nepticulidae]

Brown-tipped Pigmy


Nepticula minusculella Herrich-Schäffer, 1855. Syst. Bearb. Schmett. Europ. 5: 348.
Nepticula embonella
Klimesch, 1978. Tijdschr. Ent. 121 (5): 259, fig'd.
Stigmella minusculella
(Herrich-Schäffer, 1855).


Egg at the underside of the leaf. The mine is a not very strongly contorted corridor, also not limited to a small portion of the leaf, and usually not forming a secondary blotch. Frass black. The frass line is very narrow, especially in the first section of the mine. In the second part the line may be broader, with the frass dispersed or indistinctly coiled, but always the width of the frass remains less than a third of the width of 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).

Bright green; see Gustafsson and van Nieukerken (1990a) and Schoorl (1985a) for a description (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).
