During courtship, males of Chrysopa perla extrude from the genital aperture two eversible vesicles that bear approximately 50 sclerotized tubercles with a long, apical hair. Ultrastructural study reveals within each tubercle two juxtaposed subunits: a sensory subunit formed by a mechanoreceptor neuron, a glial cell, two enveloping cells, and a glandular subunit consisting of a glandular cell provided with an extracellular reservoir, a duct cell and an enveloping cell. The glandular-cell cytoplasm is characterized by extensive RER, a large amount of SER, probably involved in lipid elaboration, and voluminous myeloid bodies encircling the reservoir. The secretion is released to the outside by a cuticular duct that opens into the side of the tubercle. The function of the mechanoreceptor associated with the glandular subunit is discussed.
在求偶期间，普通草蛉的雄性个体从生殖孔挤出两个可外翻的囊泡，囊泡上带有大约50个具长顶端毛的硬化瘤。超微结构研究显示，每个瘤内有两个并列的亚单位：一个由机械感受器神经元、一个神经胶质细胞、两个包被细胞组成的感觉亚单位，以及一个由具有细胞外储存库的腺细胞、一个导管细胞和一个包被细胞组成的腺亚单位。腺细胞的细胞质特征为有广泛的粗面内质网、大量可能参与脂质合成的滑面内质网，以及围绕储存库的大量髓样体。分泌物通过通向瘤侧面的表皮导管释放到外部。文中讨论了与腺亚单位相关的机械感受器的功能。
