The moth family Arctiidae represents a model system for investigating the relative roles of natural and sexual selection in molding courtship and defensive behaviors. During their evolution, two different defense signals (aposematism, ultrasound) have been incorporated independently into courtship behaviors. Plant derived chemicals are sequestered and used for defense in larvae and adults, and one class of these, pyrrolizidine alkaloids, have been incorporated into male courtship pheromones in many species. Another defense signal, ultrasound, is used by adults to deter bat predation. The second defense mode is then incorporated into courtship behaviors of some arctiid species. To date, our ability to study the evolution of tiger moth defense and mating signals has been hampered by the lack of modern systematic studies at all taxonomic levels of the family. The proposed work will comprise revisionary systematic and comparative biology components. Precise descriptions of arctiid male courtship and ultrasound producing structures will be obtained, and systematic tree derived using these and other data.

蛾科Arctiidae代表了一个模型系统，研究自然选择和性选择在塑造求爱和防御行为中的相对作用。 在它们的进化过程中，两种不同的防御信号（警戒，超声波）已经独立地被纳入求爱行为。 植物衍生的化学物质被隔离并用于幼虫和成虫的防御，其中一类吡咯里西啶生物碱已被纳入许多物种的雄性求偶信息素中。 另一种防御信号，超声波，被成年蝙蝠用来阻止捕食。 第二种防御模式，然后被纳入一些arctiid物种的求偶行为。 到目前为止，我们的能力，研究进化的虎蛾防御和交配信号一直受到阻碍，缺乏现代系统的研究，在所有的分类水平的家庭。 拟议的工作将包括修订系统和比较生物学的组成部分。 精确的描述arctiid男性求偶和超声波产生的结构将获得，和系统树推导使用这些和其他数据。
