Stigmella tiliae (Frey, 1856)
[Lepidoptera: Nepticulidae]

Lime Pigmy


Nepticula tiliae Frey, 1856. Tin. Pteroph. Schweiz.: 375.
Stigmella tiliae
(Frey, 1856).


Leaf-miner: A contorted gallery, early part in underside of leaf (British leafminers).

Egg at the underside of the leaf. The mine is a gradually widening corridor. Its first part generally is lower-surface, hardly visible from above; further on the mine is full depth. Frass deposition very variable, mostly in a narrow central line throughout, but sometiimes widely dispersed or even coiled (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 pale yellow, head pale brown (British leafminers). Pale yellow; 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).
