内陆沃茨覆盖不到地球表面的百分之一，但却拥有超过百分之六的昆虫物种：来自12个目的近10万种昆虫在淡水中度过一个或多个生命阶段。尽管人们认为异域物种形成和生态适应是主要机制，但对这种显著的多样性是如何产生的却知之甚少。淡水栖息地特别容易受到环境变化的影响，并表现出明显的生态梯度。水生昆虫的两栖生活方式导致了物种多样性中灭绝、异域和非异域物种形成的复杂贡献。与缺乏进化研究相反，水生昆虫的生态学和栖息地偏好已被深入研究，部分原因是它们被广泛用作生物指示剂。水生昆虫遗传学与广泛的生态学数据相结合，为未来的研究提供了一个有前途的途径，使水生昆虫非常适合用于生态多样性研究的模型。
Inland waters cover less than one percent of Earth’s surface, but harbor more than six percent of all insect species: nearly 100,000 species from 12 orders spend one or more life stages in freshwater. Little is known about how this remarkable diversity arose, although allopatric speciation and ecological adaptation are thought to be primary mechanisms. Freshwater habitats are exceptionally susceptible to environmental change, and exhibit marked ecological gradients. The amphibiotic lifestyles of aquatic insects result in complex contributions of extinction and allopatric and non-allopatric speciation in species diversification. In contrast to the lack of evolutionary studies, the ecology and habitat preferences of aquatic insects have been intensively studied, in part because of their widespread use as bio-indicators. The combination of phylogenetics with the extensive ecological data provides a promising avenue for future research, making aquatic insects highly suitable models for the study of ecological diversification.
