美国本土的蜜蜂物种提供了宝贵的授粉服务。对本土蜜蜂数量下降的担忧正在增加，有人呼吁建立一个全国性的监测计划。通过覆盖完整性分析在生态上有意义的尺度上记录物种范围是从物种到社区跟踪蜜蜂的基本步骤。所有现有的蜜蜂标本都数字化可能需要几十年的时间，因此现在需要预测未来的研究和管理工作。从192.3万条记录中，我们创建了美国本土近88%（3158种）蜜蜂物种的范围图，提供了一个主要昆虫分支的数字化标本的库存完整性的第一次分析，也许最重要的是，估计空间完整性占美国收藏的所有已知蜜蜂标本，包括未数字化的蜜蜂标本。完整性分析是非常低的（3-37%）在四个检查的空间分辨率时，使用目前可用的蜜蜂标本记录。增加来自社区科学数据源的观测子集并没有显著提高完整性，增加预计的470万个未数字化的标本只增加了12- 13%的完整性。对包括预计标本记录在内的数据的评估表明，分类和地理方面的缺陷持续存在。在加快数字化的同时，将需要将社区科学数据与以布鲁塞尔为基础的文件相结合的新库存，以缩小这些差距。为了更全面地了解美国蜜蜂的分布，需要战略库存和加速数字化活动的共同努力。
Native bee species in the United States provide invaluable pollination services. Concerns about native bee declines are growing, and there are calls for a national monitoring program. Documenting species ranges at ecologically meaningful scales through coverage completeness analysis is a fundamental step to track bees from species to communities. It may take decades before all existing bee specimens are digitized, so projections are needed now to focus future research and management efforts. From 1.923 million records, we created range maps for nearly 88% (3158 species) of bee species in the contiguous United States, provided the first analysis of inventory completeness for digitized specimens of a major insect clade, and perhaps most important, estimated spatial completeness accounting for all known bee specimens in USA collections, including undigitized bee specimens. Completeness analyses were very low (3-37%) across four examined spatial resolutions when using the currently available bee specimen records. Adding a subset of observations from community science data sources did not significantly increase completeness, and adding a projected 4.7 million undigitized specimens increased completeness by only an additional 12-13%. Assessments of data, including projected specimen records, indicate persistent taxonomic and geographic deficiencies. In conjunction with expedited digitization, new inventories that integrate community science data with specimen-based documentation will be required to close these gaps. A combined effort involving both strategic inventories and accelerated digitization campaigns is needed for a more complete understanding of USA bee distributions.
