在P. terrae-novae中，雄性求偶行为开始于向雌性奔跑，然后是安装，定向和交配。雄性的性活动在成虫羽化后的第二天就开始了，如果提供了“马麦”酵母提取物和牛奶，糖和水的溶液。两种性别对挥发性引诱剂均无反应。其他男性在从性活跃的男性那里引发“邂逅”方面与女性同样有效，在孤立的全男性文化中，男性的邂逅率与男性在有吸引力的女性面前的邂逅率相同。虽然有吸引力的女性不影响男性的行为之前，接触他们引起了更多的机会完成的模式后，遇到，而与其他男性的较量往往会中断在求爱的早期阶段。相对于针对其他性活跃男性的性行为，针对新出现的任何性别个体的性行为都受到抑制。来自混合性别文化的男性逐渐变得对其他男性有吸引力，这些男性对他们的反应就像他们是有吸引力的女性一样。这可能是由于他们的污染与女性信息素的“安装兴奋剂”类型。虽然只喂糖和水的雄性动物性活动的频率大大降低，但它们的性别歧视机制仍然没有受到损害。在雄性活跃的文化中，新出现的雌性在成年后的第二天变得有吸引力并交配。约4%的雄性攻击配偶导致交配的雄性改变。交配后，雌性会通过腹部的翅膀水平振动来拒绝雄性的任何进一步关注。这减少了安装的时间，并防止生殖器接触，否则交配的女性和处女一样有吸引力。女性的振动反应主要是引起安装，特别是在定向后，但从来没有接触前的男性。雄性用后腿的“推”来拒绝求爱，就像在打扫房间一样。当坐骑持续存在时，这会起作用，尽管定向和生殖器延伸的机会减少，但坐骑的机会不会减少。
In P. terrae-novae the male courtship behaviour begins with a run towards the female followed by mounting, orientation, and copulation. Male sexual activity begins on the second day after adult emergence if supplied with a solution of "Marmite" yeast extract and milk, sugar, and water. No reactions to a volatile sex attractant could be demonstrated from either sex. Other males are equally effective as females in eliciting "encounters" from sexually active males, and the encounter rate of males in isolated all male cultures is the same as that of males in the presence of attractive females. Though attractive females do not affect the male behaviour before contact they elicit an increased chance of completion of the pattern after encounter, whereas bouts with other males tend to break off in the early stages of courtship. Sexual behaviour directed towards newly emerged individuals of either sex is inhibited relative to that directed towards other sexually active males. The males from mixed-sex cultures gradually become attractive to other males, which respond to them as if they were attractive females. This may be due to their contamination with a female pheromone of the "mounting stimulant" type. Though males fed only on sugar and water showed a vastly reduced rate of sexual activity, their mechanism of sex discrimination remained unimpaired. In cultures with active males, newly emerged females become attractive and mate on the second day after adult emergence. About 4% of the attacks by males on pairs in copula result in a clnange of copulating male. After copulation females reject any further attention from males by horizontal vibration of their wings across the abdomen. This reduces the duration of mounting and prevents genital contact, otherwise mated females are as attractive as virgins. The female vibration response is elicited mainly on mounting, especially after orientation, but never before contact by the male. Males reject courtship with a "pushing" of the hind legs as in cleaning. This operates when a mount persists, and though the chances of orientation and genital extension are reduced the chance of mounting is not.
