Neuroterus quercusbaccarum Linnaeus, 1758

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

Life history. The sexual generation induces the largest catkin galls on oaks in Israel. These are fleshy, spherical galls, up to 8 mm in diameter, smooth, shiny, light green with purple ‘veins’ and single-chambered ( Fig. 27 View FIGURES 23–28 ). The asexual generation induces dome-shaped leaf galls, up to 6 mm in diameter, with a pointed central projection, single-chambered, usually in clusters ( Fig. 35, 36A View FIGURES 35–40 ). When young, the galls are pale green, sometimes covered by very short, reddish hairs, turning pink as they mature.

Phenology. Galls of the asexual generation appear in August, drop from the leaves in November-December and adults emerge from them in March. Galls of the sexual generation appear in March and adults emerge from them in April-May.

Distribution. Israel: Known from galls of both generations throughout the distribution range of Q. boissieri . Elsewhere: Common and widespread from Northwestern Africa to Norway, Russia and Iran.

Comments. Galls of the asexual generation are similar to those of Neuroterus tricolor Hartig in Europe but the latter are spherical rather than dome-shaped and do not have a central pointed projection.
