Si je suis la clef de W. Ellis :
1b under-surface tentiform mine => 2
2a m ine strongly inflated, almost the entire leaf folding over it; upper side white-mottled; cremaster with two pairs of thorns that are set close together; especially the outer pair stout: Phyllonorycter nigrescentella
ou
2b mine weakly inflated, upper side largely green; cremaster with two pairs of thread thin
La deuxième n'est pas illustrée mais me semble mieux correspondre :
La première :Lower surface tentiform mine that occupies only part of a leaflet. In full grown leaves the mine is strongly inflated an is largely hidden by the leaf. Contrary to other species not the entire leaflet is mined out.
Larvae in July and September – October (Emmet ao, 1985a).
Des avis ?Lower surface tentiform mine that occupies an entire leaflet; lower epidermis strongly folded. Fully developed mines are strongly inflated and the leaflet is so completely folded over the mine that the latter becomes practically invisible. In this stage the larva has consumed also all tissue in the roof of the mine, making the mine thereby very conspicuous. The pupa in a cocoon that consists of a loose lining of the walls of the mine.
Ajouté moins d'une heure après :
P.S. Je me rends compte qu'il y a deux mines de deux folioles différentes mais elles sont semblables, le dessous de la première est également semblable au dessous de la seconde.
