D'après W. Ellis :
1a mine upper- or lower-surface; frass in two lines; larva a maggot => 2
2a corridor from start to end => 3
3a first part of the corridor in a tight spiral; leaf tissue there often discoloured : Liriomyza eupatorii
Les photos du site ressemblent tout à fait à ça.
Ajouté moins d'une heure après :
Upper-surface corridor. The first part is wound in a dense spiral that quickly turns brown. The spiral continues in a long, generally unbranched corridor that maintains almost the same width. Frass in long thick strings. When the mine is positioned near the leaf margin the spiral part may be missing; the thick frass strings then are sufficiently characteristic. Pupation outside the mine; exit slit in lower epidermis.
A very common species, mostly found on Eupatorium and Galeopsis.
Larvae in May-June and July-August (Hering, 1957a).
