The morphology of the compound eye of the noctuid moth Spodoptera exempta was investigated by electron microscopy. This eucone superposition eye is composed of about 8000 ommatidia. Each ommatidium is surrounded by six secondary pigment cells showing pigment movement according to the state of adaptation. It contains four crystalline cone cells forming together a crystalline cone and tract, two primary pigment cells, which encompass the crystalline cone, and usually eight retinula cells. On the basis of their rhabdomeric structure, three types of retinula cells can be distinguished. According to the structure of the rhabdom, two types of ommatidia are found in different regions of the eye. The rhabdom of the lobed type, providing more than 80% of ommatidia, is composed of V-shaped rhabdomeres with fanwise arranged microvilli. The rhabdom of the square type, found in a small area in the dorsal region of the eye, consists of triangular rhabdomeres with parallel microvilli. The functional significance of this difference is discussed.
利用电子显微镜对夜蛾草地贪夜蛾复眼的形态进行了研究。这种真晶锥重叠眼由约8000个小眼组成。每个小眼被六个次生色素细胞包围，这些细胞根据适应状态显示色素移动。它包含四个晶锥细胞，共同形成一个晶锥和晶锥束，两个包围晶锥的初级色素细胞，以及通常八个视杆细胞。根据它们的视杆结构，可以区分出三种类型的视杆细胞。根据视杆的结构，在眼睛的不同区域发现了两种类型的小眼。叶状类型的视杆提供了超过80%的小眼，由呈扇形排列微绒毛的V形视杆节组成。方形类型的视杆位于眼睛背侧的一个小区域，由具有平行微绒毛的三角形视杆节组成。讨论了这种差异的功能意义。
