Plant Parasites of Europe

leafminers, galls and fungi

Ectoedemia caradjai

Ectoedemia caradjai (Groschke, 1944)

Ectoedemia caradjai mine

Quercus cf pubescens, Rhodes; from Klimesch (1978b)

Ectoedemia caradjai mine

Quercus macrolepis, Anatolia; from Klimesch (1978b)


Oviposition of the underside of the leaf. The mine is a short, strongly contorted corridor, almost completely filled with frass, widening into a pear-shaped upper-surface blotch with the frass in its basal part. Pupation external.

host plants

Fagaceae, monophagous

Quercus coccifera, frainetto, ithaburensis subsp. macrolepis, petraea, pubescens, pyrenaica, robur.


Larvae in July – August, much earlier than the other Ectoedemias on oak; in southern Europe at least three generations per year (van Nieukerken ao, 2006a, 2010a).

distribution within Europe

South of the line France, Czechia, Ukraine (Fauna Europaea, 2009).


Green; ventral plates absent.


Nepticula, Stigmella caradjai.


Hering (1932g) was the first to recognise this species, but he described only the mine. According to the rules of nomenclature the description of “the work of an animal”, published after 1930, does not form an available publication. The first available description was by Grosche (1944a).
