The egg of the leafhopperEuscelis plebejus was deformed by involuting both egg poles in longitudinal direction until the egg poles touched inside the egg. Even under those conditions a complete germ band with normal sequence of segments may be formed.
叶蝉Euscelis plebejus的卵通过纵向内卷卵的两极直至两极在卵内接触而发生变形。即便在这些条件下,也可能形成具有正常节段序列的完整胚带。
