扫描电镜观察到丽蝇科（Calliphoridae）、家蝇及近缘种（Muscophagae）和肉蝇科（Sarcophagidae）的足爪间垫状结构，即粘着器的超微结构。蝇种为Chani蝇、黑足蝇、红腹蝇和维伦纽维蝇;而家蝇及其近缘种分别为家蝇和铜腹水虻。新鲜蝇种包括白尾双翅目（Boettcherisca peregrina）和嗜蝇类（Liophaga dux）。在枕的腹侧观察到许多附着刚毛。结果表明，该刺的两个特征是：（1）刺端呈铲状（inC.查尼角（C. pinguis，C. nigripes、黑足M. Alternatica，H. chalcogaster，B. peregrina和L. dux）和匙状尖端（inC. villeneuvi）。透射电镜下观察了黑腹叶蜂的寄生刚毛。Domestic发现电子透明的物质位于中心，表明是一种粘附物质。这些结果提供了解剖学信息，使我们不仅能够理解苍蝇成功附着在光滑表面上，而且还澄清了它们作为微生物机械载体的作用。
The ultrastructure of adhesive device or the pulvilli, pad-like structure between the tarsal claws of the legs, is presented in the blowfly (Calliphoridae), housefly and relatives (Muscidae), and flesh fly (Sarcophagidae) through scanning electron microscopy. The blowfly species wereChrysomya chani,Chrysomya nigripes,Chrysomya pinguis, andChrysomya villeneuvi; while those of the housefly and relatives wereMusca domesticaandHydrotaea chalcogaster, respectively. Fresh fly species includedBoettcherisca peregrinaandLiosarcophaga dux. Numerous tenent setae were observed on the ventral side of the pulvilli. Two features of the tip of the tenent setae were found as a spatula-like (inC. chani,C. pinguis,C. nigripes,M. domestica,H. chalcogaster,B. peregrina, andL. dux) and spoon-like tip (inC. villeneuvi). Transmission electron microscopy of the tenent setae inM. domesticarevealed the electron-lucent centrally located, suggesting an adhesive substance. These results provided anatomical information that allow us to not only understand the successful attachment of flies to smooth surfaces but also clarify their role as a mechanical carrier of microorganisms.
