Stigmella magdalenae (Klimesch, 1950)
[Lepidoptera: Nepticulidae]

Northern Rowan Pigmy


Nepticula magdalenae Klimesch, 1950. Ent. Nachr. Bl. öst. Schweiz. Ent. 2 :72.
Stigmella magdalenae
(Klimesch, 1950).


Leaf-miner: A long thin linear gallery with frass in a thin line, sometimes broken. This distinguishes it form S.nylandriella, which never has linear frass throughout the mine. The gallery of S.magadalenae is also narrower than S.nylandriella . S. magdalenae can both be an edge miner or make a small mine in the leaf blade, or run along a vein (British leafminers).

Egg at the underside of the leaf, independent of the venation. The corridor is narrow from start to end, and compressed on a small space, sometimes following the leaf margin for a while, more often along a major vein. Frass in a narrow, regularly interrupted central line. In thick leaves the frass line is broader, and the corridor is shorter (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; Emmet, 1983a; Schoorl et al., 1985a; 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).
