Cynips divisa Hartig, 1840  

Host plants. Israel: Q. boissieri   . Elsewhere: several oak species from section Quercus   .

Life history. Both the sexual and asexual generations are known but in Israel only the leaf galls of the asexual generation were found. These are spherical, detachable galls on the underside of the leaves, 4–6 mm in diameter and single-chambered ( Fig. 33 View FIGURES 29–34 ). Young galls are green and fleshy, turning golden-brown and thick-walled when mature. Galls of the sexual generation are small, conical, single-chambered leaf-margin galls with a small apical tip.

Phenology. In Europe, galls of the asexual generation begin to develop in June and adults emerge from them in October-November or in February-March of the following year. In Israel they were found in July but no adults were reared from them. Galls of the sexual generation develop rapidly after leaf burst in spring and adults emerge in May.

Distribution. Israel: Throughout the distribution range of Q. boissieri   . Elsewhere: A common species from the Iberian Peninsula to Transcaucasia and Iran.

Comments. Galls of the asexual generation of this species are somewhat similar to those of Cynips quercus   on the same host plant ( Fig. 32 View FIGURES 29–34 ) but are smaller and golden-brown rather than green.
