Based on examination of ~180,000 specimens from 695 collections of 443 localities collected from the 1930s to 2015 we report 295 species of caddisflies from Michigan. Of these, 41 are reported from the state for the first time. Another 18 species previously reported from Michigan are listed as doubtful. The 11 most abundant species collectively represented over half of all specimens collected. Conversely, 80 species were known from <10 specimens, and 27 species from a single specimen. The Michigan fauna is similar to those of Minnesota and Ohio, adjacent states with comparable recent collecting effort. Regional and habitat affinities for each Michigan species are reported herein. Due to the high level of species discovery over the last few years, despite a >80-year collecting history, it is likely that additional species remain undiscovered in the state.
基于对1930年代至2015年期间从443个地点的695个馆藏中收集的约180,000个标本的检查，我们报告了密歇根州的295种毛翅目昆虫。其中，有41种是该州首次报道。另外，先前在密歇根州报道过的18种被列为可疑物种。11种数量最多的物种共同占所有采集标本的一半以上。相反，有80种已知标本数量少于10个，27种仅知有1个标本。密歇根州的动物区系与明尼苏达州和俄亥俄州相似，这两个相邻州近期的采集工作力度相当。本文报告了密歇根州每个物种的区域和栖息地亲缘关系。尽管有超过80年的采集历史，但由于过去几年物种发现水平较高，该州很可能仍有其他物种未被发现。
