Inside the Gallapfels (also Folii Galle or Blattgalle called) is a larva, from which in the autumn then the always female insect hatches, which puts ever a unbefruchtetes egg into the vegetation cone of the oak bud. This wintered there and forms starting from spring bud-close-budding close all (Taschenbergii Gallen) out of those then in June both for males and females of the calibration close all wasp slips. The fertilized females placing then again eggs with the help of the putting prick into a vein of the oak sheet. From a defence reaction of the oak the diseased rampant growth around the putting place, which is called due to the sphericalness Gallapfel, results.
