Ectoedemia haraldi (Soffner, 1942)

Quercus ilex, France, Angoulème; from Soffner (1942a)
mine
Egg at the upperside of the leaf, not near a vein. The mine is an, especially at first, rather straight corridor, that widens only a little. Frass black, in a broad band that almost entirely fills the corridor.
hostplants
Fagaceae, monophagous
Quercus coccifera, ilex, rotundifolia, suber.
phenology
One generation; larvae have been collected from February till March.
distribution within Europe
Mediterranean Region from Iberia and southern France to Greece; also Corsica and Crete (Fauna Europaea, 2009).
larva
Whitish; head and prothoracic plate dark brown; ganglia conspicuous, dark brown; no ventral plates. Soffner (1942a) describes the larva.
synonyms
Nepticula, Stigmella haraldi.
notes
Throughout the Mediterranean this is the commonest Ectoedemia on evergreen oaks (van Nieukerken ao, 2006a).
The mines can hardly be distinguished from those of E. algeriensis, alnifoliae,coscoja, ilicis, and pseudoilicis. In comparison with these the mine generally is less contorted, therefore occupies a larger surface of the leaf, als also is somewhat larger (van Nieukerken ao, 2010a).
