The functions of the gustatory, olfactory, touch and stress receptors on the cerci of Lucilia cuprina Wied. (Diptera: Calliphoridae) are apparent from the morphology of their distal dendritic segments and associated cuticular structures. Each trichoid mechanoreceptor has a dendrite containing a tubular body at the base of the hairshaft. The suspension fibres and socket septum may be involved in transmitting a stimulus to the dendrite terminal and restoring the hair to its resting position. The campaniform sensilla are considered as trichoid mechanoreceptors with reduced hair shafts and socket structures, reflected in fusion of the suspension fibres into the inner cuticle of the dome and loss of the socket septum. Fusion and reduction of the socket structures is also apparent at the bases of the olfactory pegs. They differ from typical antennal olfactory sensilla in having a flexible socket and relatively thick walls; features which may protect them from damage during ovipositor probing of potential oviposition substrates. The two types of cereal gustatory sensilla differ in their complement of chemosensory dendrites, one has three, the other four, the latter type also has a mechanoreceptive dendrite at the base of the hair shaft. Both types have socket structures resembling those of the trichoid mechanoreceptors.
黑边蕈蝇（双翅目：丽蝇科）尾须上味觉、嗅觉、触觉和压力感受器的功能从其远端树突状末梢和相关表皮结构的形态上可以明显看出。每个刚毛机械感受器的树突在毛发轴的底部包含一个管状主体。悬丝和插座隔片可能参与将刺激传递到树突末梢，并将毛发恢复到静止位置。鼓形感觉器被认为是具有减少毛发轴和插座结构的刚毛机械感受器，这反映在悬丝融合到穹顶的内表皮中以及插座隔片的缺失。在嗅觉刺的基部也明显存在插座结构的融合和减少。它们与典型的触角嗅觉感受器不同，具有灵活的插座和相对较厚的壁；这些特征可能在产卵器探测潜在产卵基质时保护它们免受损坏。两种类型的谷物味觉感受器在其化学感觉树突的组成上有所不同，一种有三个，另一种有四个，后者类型在毛发轴的基部还有一个机械感觉树突。两种类型都有类似于刚毛机械感受器的插座结构。
