The dance flies (Diptera: Empididae: Empidinae), a lineage of over 2,000 species, exhibit a suite of specialized mating behaviors and morphology that place them among the most commonly cited examples of sexual selection in insects. They are the subject of many detailed behavioral studies and textbook examples. This collaborative study integrates molecular, behavioral and morphological data collection to develop a comprehensive evolutionary classification for the Empidinae. Evolution of behavior and sexual morphology is studied within specific focal clades to identify key traits involved in swarming, sex-role reversal, presentation of nuptial gifts ("ballooning"), and intersexual conflict. Genetic data are used to frame and inform tests of evolutionary hypotheses concerning generation of diversity in dance flies and examine the implication of these findings other organisms. Project results will test long-standing hypotheses on mating system evolution and provide key empirical evidence in support of the hypothesized link between sexual selection and diversification rate dynamics in a diverse lineage of insects. The project involves academic training and a program of outreach, including educational material that will be presented via the project website, and online resources for undergraduate and K-12 levels.

舞蹈苍蝇（双翅目：Empididae：Empidinae）是一种超过2,000种的谱系，表现出一套专业的交配行为和形态，使它们成为昆虫中最常见的性选择例子。它们是许多详细的行为研究和教科书示例的主题。 这项合作研究将分子，行为和形态数据收集整合在一起，以开发针对empidinae的全面进化分类。 在特定的焦点进化枝中研究了行为和性形态的演变，以识别涉及蜂群，性角色逆转，婚礼呈现（“膨胀”）（“ balloning”）的关键特征和两性冲突。 遗传数据用于构建和告知关于舞蹈蝇中多样性的进化假设的测试，并研究这些发现的其他生物的含义。项目结果将检验有关交配系统演化的长期假设，并提供关键的经验证据，以支持在多样化昆虫谱系中性选择与多样化率动态之间的假设联系。 该项目涉及学术培训和宣传计划，包括将通过项目网站介绍的教育材料以及本科和K-12级别的在线资源。
