Israel : Q. ithaburensis and Q. libani . Elsewhere: Q. libani , Q. brantii , Q. castaneifolia . Life history. Known only from the bud galls of the asexual generation, which are spherical, single-chambered, 10–14 mm in diameter, with velvety, sometimes slightly wrinkled surface, broadly attached to the branch or sometimes to the trunk ( Fig. 37 ), often in clusters of 5–8. The gall contains an internal ovoid chamber that is attached to the inside wall in young galls but detaches from it and rolls freely inside the mature gall ( Fig. 38 ). Young galls are light green, turning brown when mature. Old galls remain on the trees for several years. Phenology. Galls appear in August and adults emerge from them in October-November. In the present study one adult emerged from a gall on Q. libani in January. Distribution. Israel : Common on Q. ithaburensis throughout its distribution range; on Q. libani found only on Mt. Hermon at 1780 m .a.s.l. Elsewhere: Turkey , Syria , Lebanon , Iran . Comments. Galls of A. persica are very similar to those of A. cerricola and A. kordestanica but these species have not been found in Israel . The galls are often invaded by the inquiline Synergus variabilis Mayr , especially on Q. ithaburensis . An invaded gall is bigger, irregularly shaped and multichambered ( Figs 39–40 ), whereas an uninvaded gall is spherical and single-chambered ( Figs 37–38 ). Sternlicht (1968b) listed the axesual generation of Andricus kollari Hartig as occurring in Israel (his Figs 18–20 ) but we never found this species in Israel and conclude that Sternlicht mistook its galls for those of Aphelonyx persica . Galls of the two species are somewhat similar in shape and colour but those of A. kollari develop only on oaks from section Quercus .
