The external morphology of contact-chemoreceptive hairs (taste hairs) of six fly species, Calliphora vicina, Lucilia caesar, Musca domestica, Phormia terranovae, Sarcophaga carnaria and Stomoxys calcitrans, is described. The species can be distinguished by the differences between the patterns of taste hairs at the ventral side of their prothoracic tarsi. Taste hairs can be subdivided into morphological types, using the shape of the cuticle around the apical pore as criterion, even though this shape changes slightly on opening and closing of the pore. Light microscopical studies reveal that the nature and osmolarity of stimuli are decisive for the effect stimuli have on the shape of the top of the labellar hairs. The motions of the apical cuticle appear to be reversible. Gentle ultrasonic treatment preserves the shape of the cuticle of the top and the diameter of the pores on fluid stimulation. This technique makes it possible to study the effect of a previous stimulation on both tarsal and labellar hairs with the scanning electron microscope. It is supposed that stimuli can affect cuticular components around the pore, producing volume changes in that cuticle which alter the diameter of the pore.
描述了六种蝇类，即红头丽蝇、铜绿蝇、家蝇、新陆原伏蝇、肉蝇和厩螫蝇的接触化学感受毛（味觉毛）的外部形态。这些物种可以通过其前胸跗节腹侧味觉毛的模式差异来区分。味觉毛可以根据顶端孔周围角质层的形状分为形态类型，尽管这种形状在孔的开闭时会略有变化。光学显微镜研究表明，刺激的性质和渗透压对于刺激对唇叶毛顶端形状的影响起决定性作用。顶端角质层的运动似乎是可逆的。温和的超声处理在液体刺激下能保持顶端角质层的形状和孔的直径。这项技术使得用扫描电子显微镜研究先前刺激对跗节毛和唇叶毛的影响成为可能。据推测，刺激可以影响孔周围的角质层成分，使该角质层产生体积变化，从而改变孔的直径。
