Eriophyes licopolii Trotter & Cecconi, 1902
Quercus ilex, galls (from Houard, 1998a)
Of this gall two rather diverging descriptions exist:
According to Houard the anthers are enlarged to 5-6 mm long and 2 mm thick, adnd covered by a reddish-brown felt of stellate hair of which the rays are cylindrical with a blunt tip. His illustration (above) indeed does show a normal catkin with galled flowers.
Stork & Wüest at the other hand write that the axis of the catkin is swollen and bears male and female flowers that have been transformed into an, initially fleshy, ultimately lignified, mass, covered by a reddish-brown felt consisting of cylindrical trichomes with a blunt tip. Old galls remind of old alder-cones.
Fagaceae, narrowly monophagous
Aceria ilicis var. licopolii.
