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.

舞飞（双翅目：舞虻科：隐翅虫亚科（Empidinae），一个超过2,000种的谱系，表现出一套专门的交配行为和形态，使它们成为昆虫性选择中最常引用的例子。他们是许多详细的行为研究和教科书例子的主题。 这项合作研究整合了分子，行为和形态学数据收集，为Empidinae制定了一个全面的进化分类。 在特定的焦点分支内研究行为和性形态的进化，以确定参与集群、性别角色逆转、婚姻礼物的呈现（“气球”）和性间冲突的关键特征。 遗传数据被用来框架和告知测试的进化假说产生的多样性在舞蹈苍蝇，并检查这些发现的其他生物的影响。项目结果将检验长期存在的关于交配系统进化的假设，并提供关键的经验证据，以支持昆虫多样化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推广计划，包括将通过项目网站提供的教育材料，以及本科和K-12水平的在线资源。
