干或“幼虫”的眼睛对于理解六足动物的主要视觉器官复眼的进化和个体发育至关重要。利用经典的神经解剖学技术，证明了Chaoborus imagos的持续干与复眼第一、二级神经柱附近的持续干神经柱相连，因此，该imago也具有与复眼的结构和发育模式密切相关的干板和髓质。研究结果进行了比较与其他节肢动物，如附件侧眼Amandibulata和多足类，建议一些祖先，而不是派生的字符状态。J. Morphol. 270：1524-1530，2009. (C)2009 Wiley-Liss，Inc.
Stemmata or "larval" eyes are of crucial importance for the understanding of the evolution and ontogeny of the hexapod's main visual organs, the compound eyes. Using classical neuroanatomical techniques, I showed that the persisting stemmata of Chaoborus imagos are connected to persisting stemma neuropils neighboring the first and second order neuropils of the compound eyes, and therefore also the imago possesses a stemma lamina and medulla closely associated with the architecture and the developmental pattern of those of the compound eyes. The findings are compared with other arthropods, e.g. accessory lateral eyes in Amandibulata and Myriapoda, suggesting some ancestral rather than derived character states. J.
