红绒茧蜂成虫被其专性寄主粉蝶（Pieris raubecula）的取食活动产生的利它素所吸引和捕获。对视频记录的分析以及对实验室和野外觅食的单个黄蜂的直接观察表明，找到宿主的能力几乎完全取决于黄蜂对这些化学线索的行为反应。黄蜂不会轻易离开有寄主取食损害的植物。当发现宿主时，由于从对宿主的攻击中恢复（梳理）所花费的时间，花费在具有进食损害的植物上的时间进一步增加。这种恢复时间和成功产卵的频率随宿主大小而变化。这些结果进行了讨论有关的寄生虫的觅食策略。
Adult female Cotesia rubecula are attracted to and arrested by kairomones produced by the feeding activities of their obligatory host, Pieris rapae. Analysis of video recordings and direct observations of individual wasps foraging in the laboratory and in the field showed that the ability to find a host depends almost exclusively on the wasps' behavioral responses to these chemical cues. Wasps do not readily leave plants that have host feeding damage. The time spent on a plant with feeding damage is further increased when a host is found because of the time spent recovering (grooming) from an attack on a host. This recovery time and the frequency of successful oviposition vary with host size. These results are discussed in relation to the parasite's foraging strategy.
