Dryocosmus mikoi Melika, Tavakoli, Stone & Azizkhani, 2006

Host plants. Israel: Q. ithaburensis . Elsewhere: Q. libani , Q. brantii and Q. castaneifolia .

Life history. Known only from the leaf galls of the sexual generation, which constitute spherical swellings at the base of leaves, up to 12 mm in diameter, with an apical ‘crest’ up to 4 mm long ( Fig. 64 ). They are singlechambered, fleshy and bright green when young, turning hard as they mature, and dark brown when old.

Phenology. Galls begin to develop in March (June in higher elevations - e.g., En Zivan) and adults emerge in May-June.

Distribution. Israel: Rare in En Zivan, Mezar, Yehudiyya, Dan and Hagoshrim. Elsewhere: Iran.
