Retinular fine structure has been compared in the superposition compound eyes of three sphingid moths, one nocturnal, Cechenena, and two diurnal, Cephonodes and Macroglossum. Cechenena and Cephonodes have tiered retinas with three kinds of retinular cells: two distal, six regular and one basal. The distal retinular cells in Cechenena are special in having a complex partially intracellular rhabdomere not present in Cephonodes. Macroglossum lacks the distal retinular cell. In Cephonodes a unique rhabdom type, formed by the six regular retinular cells in the middle region of the retinula, is divided into three separate longitudinal plates arranged closely parallel to one another. Their constituent microvilli are consequently all nearly unidirectional. The ratio of rhabdom volume to retinular cell volume in the two diurnal sphingids is 10-27%; this is about the same as that (25%) of skipper butterflies, but significantly smaller than in the nocturnal Cechenena (60%). In the diurnal sphingids retinular cell membranes show elongate meandering profiles with septate junctions between adjacent retinular cells. From the comparative fine structure of their eyes the diurnal sphingids and the skippers would appear to be phylogenetically closely related.
对三种天蛾科蛾类复眼中的小网膜精细结构进行了比较，其中一种是夜间活动的茜草天蛾（Cechenena），另外两种是日间活动的长喙天蛾（Cephonodes）和长喙天蛾属（Macroglossum）。茜草天蛾和长喙天蛾的视网膜分层，有三种类型的小网膜细胞：两种远端细胞、六种规则细胞和一种基部细胞。茜草天蛾的远端小网膜细胞特殊之处在于具有复杂的部分细胞内视杆，而长喙天蛾没有。长喙天蛾属缺少远端小网膜细胞。在长喙天蛾中，由小网膜中部的六个规则小网膜细胞形成的一种独特视杆类型，被分成三个彼此紧密平行排列的独立纵向板。因此，它们的组成微绒毛几乎都是单向的。两种日间活动的天蛾科蛾类中视杆体积与小网膜细胞体积之比为10%-27%；这与弄蝶的比例（25%）大致相同，但明显小于夜间活动的茜草天蛾（60%）。在日间活动的天蛾科蛾类中，小网膜细胞膜呈现出细长的蜿蜒轮廓，相邻小网膜细胞之间有分隔连接。从它们眼睛的比较精细结构来看，日间活动的天蛾科蛾类和弄蝶在系统发育上似乎关系密切。
