Range maps are used to estimate the geographic extent of taxa, providing valuable information for biodiversity and conservation research and management. Freshwater macroinvertebrates are not well-represented in the range map literature relative to freshwater vertebrates. To address this knowledge gap, we provide range maps for 1158 freshwater macroinvertebrate genera based on two decades of publicly available occurrence data from the USEPA National Aquatic Resource Surveys, which included 11,628 sites and 6,906,990 organisms across the contiguous USA. Maps were created by applying unweighted and weighted pair group method with arithmetic mean clustering and single-linkage clustering algorithms to the occurrence data and creating three layers of polygons from the minimum convex hulls of clusters. A total of 25 freshwater macroinvertebrate classes are represented in the range map dataset. Most mapped genera were insects (394/1158), followed by malacostracans (242/1158), polychaetes (182/1158), and bivalves (121/1158). Additionally, we provide waterbody type percent occupancy data for all genera, detailing how genera are partitioned between boatable streams, wadeable streams, inland lakes, Laurentian Great Lakes, and coastal estuaries.
范围图用于估计分类单元的地理范围，为生物多样性和保护研究以及管理提供有价值的信息。与淡水脊椎动物相比，淡水大型无脊椎动物在范围图文献中的代表性不足。为了弥补这一知识空白，我们根据美国环保署国家水生资源调查 20 多年来公开提供的现有数据，为 1158 个淡水大型无脊椎动物属提供了范围图，这些数据包括美国大陆的 11628 个地点和 6906990 个生物。通过对出现数据应用无加权和加权对组平均聚类和单链接聚类算法，并从聚类的最小凸壳创建三个多边形层，创建了地图。范围图数据集共涵盖 25 个淡水大型无脊椎动物类群。大多数映射的属为昆虫（394/1158），其次是软甲纲（242/1158）、多毛纲（182/1158）和双壳纲（121/1158）。此外，我们还提供了所有属的水体类型百分比占有数据，详细说明了属如何在可划船溪流、可涉水溪流、内陆湖泊、大湖地区和沿海河口之间划分。
