与许多其他双翅目昆虫一样，雌性果蝇在被斩首后还能活几天。这种被砍头的雌性果蝇的直立姿态与普通果蝇相当，能够而且确实从事复杂的动作，比如梳理毛发、飞行，在胁迫下还会行走。尽管有物种差异，大多数果蝇的雄性都会向被砍头的雌性求爱。迄今为止，所有被斩首的雌性都把雄性的求爱行为当作有害的外来刺激来对待。如果通过强制攻击，雄性与被斩首的雌性实现了生殖器插入，那么交配在各方面都是正常进行的。雄性对被斩首的雌性的求偶行为清楚地表明，雌性的求偶行为是由它从雌性那里得到的一系列刺激决定的，而雌性产生的各种刺激中的任何一种的相对重要性在不同的物种之间都是不同的。然而，在关系密切的物种中，雄性的反应却相当相似。利用被斩首的雌性果蝇可以作为分析果蝇求偶行为和性隔离机制的有效工具。
Female drosophillds, in common with many other Diptera, will live for several days after they have been decapitated. Such beheaded females assume an upright stance comparable to that of a normal fly and can and do engage in complex actions such as preening, flying and, under duress, walking. Although species specific variations occur, males of most spp. of Drosophila will court their decapitated females. All decapitated females of all spp. studied to date treat the courting overtures of the males as if they were noxious foreign stimuli. If by forcible assault the male achieves genitalic intromission with a decapitated female, then the copulation proceeds normally in all respects. Male courtship behavior with decapitated females clearly shows that the initiation of courtship by the female is determined by a number of stimuli that he receives from the female and that the relative importance of any 1 of these diverse female-produced stimuli varies between spp. Males of closely related spp., however, show considerable similarity in their responses. The use of decapitated females can serve as an efficient tool for the analysis of courtship behavior and the sexual isolating mechanisms of the genus Drosophlla.
