Ectoedemia hannoverella: larva in its gall

Populus x canadensis, Belgium, prov. Namur, Couvin, Mariembourg © Stéphane Claerebout: larva in the galled petiole


Oviposition in the petiole, c. a cm below the base of the leaf. The larve begins its life as a borer in the petiole, causing it to locally swell somewhat. Once the larva has reached the leaf disc it begins forming an elongate blotch between the leaf margin and the most lateral vein, or, more rarely, between the midrib and the first lateral vein. Frass in two stripes, parallel to the sides of the mine. Pupation external.

The larvae feed only at night, retreating within the petiole at daytime. The larva can be lured into the mine by keeping the leaf in the dark for a while (Borkowski, 1969a). The arrangement of the frass in two stripes is the result of the regular movement of the larva.

host plants

Salicaceae, monophagous

Populus x canadensis, nigra.


Larvae probably already present in July in the petioles, in the leaf disc from end-September – October; mines often in green islands, also in fallen leaves (Hering, 1957a).


BE recorded (Phegea, 2009).

NE recorded (Kuchlein & de Vos, 1999a;, 2009).

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Europe, except the British Isles, perhaps also Greece (Fauna Europaea, 2009).



Nepticula, Stigmella hannoverella.
