The galls of this species are not as well represented in the collections as the similar galls of Cynips divisa. Agama galls are to be distinguished by their smaller size, more uniformly ellipsoidal shape, and much thinner walls. The young galls appear in June (acc. Mayr 1872), becoming mature by the end of August (acc. Connold 1908) or early in September (acc. Kieffer 1901). The non-parasitized galls are deciduous (acc. Kieffer 1901). The adults emerge in October and November (acc. Schlechtendal 1870 and Mayr 1882), more often in November (acc. Kieffer 1901). Further data on the biology of the species are not available. The alternating bisexual insect is not recognized, but it may be expected to inhabit a small cell-like gall in the buds or on the leaves of
