果蝇（Brachycera）在跗节末端有一个称为pulvilli的粘性垫。垫被附着的刚毛覆盖，有时称为附着毛，用于增加实际。附着于表面的区域。透射电镜和扫描电镜观察表明，近端和远端的持毛具有不同的超微结构。远端粘性刚毛的设计适于在接触区域附近释放粘性物质。它的结论是分泌物注射精确地针对下的一个单一的刚毛的远端尖端。
Flies (Brachycera) have adhesive pads called pulvilli at the terminal tarsomere. The pulvilli are covered by tenent setae, sometimes termed tenent hairs, which serve to increase the actual. area of attachment to the surface. By using transmission and scanning electron microscopy it is shown that proximal and distal tenent setae have different ultrastructures. The design of distal adhesive setae is adapted for the release of adhesive substances close to the area of contact. It is concluded that secretion injection is precisely targeted under the distal tip of a single seta.
