Studies of the dorsal ocelli of the wasp Paravespula vulgaris (L.) led to the following results: Under a biconvex corneal lens, 150 microns in thickness, about 600 receptor cells are located. The rhabdomeres of two adjacent cells form a closed plate-like rhabdom (0.5--1.0 micron in thickness, 6 microns in width and 10--25 microns in depth or length). In the lateral ocellus the receptor cells synapse up to 8 ocellar nerve fibers, and in the median ocellus they synapse up to 16 (20--30 microns thick) ocellar nerve fibers. The ocellar synaptic plexus may display three types of synapses between the two types of neurons: (i) Receptor-cell axons are presynaptic to dendrites of the first-order interneurons. (ii) Dendrites of the first-order interneurons are presynaptic to receptor-cell axons. (iii) The subunits of a dendrite of first-order interneurons form synapses with each other.
对普通黄胡蜂（Paravespula vulgaris (L.)）背单眼的研究得出了以下结果：在一个厚度为150微米的双凸角膜透镜下，约有600个感受器细胞。两个相邻细胞的视杆形成一个封闭的板状视杆（厚度为0.5 - 1.0微米，宽度为6微米，深度或长度为10 - 25微米）。在侧单眼中，感受器细胞与多达8条单眼神经纤维形成突触，而在中单眼中，它们与多达16条（20 - 30微米厚）单眼神经纤维形成突触。单眼突触丛在两类神经元之间可能呈现三种突触类型：(i) 感受器细胞轴突是一级中间神经元树突的突触前成分。(ii) 一级中间神经元的树突是感受器细胞轴突的突触前成分。(iii) 一级中间神经元树突的亚单位相互形成突触。
