Wild bee communities in urban ecosystems are often challenged by habitat fragmentation and low floral diversity. In such settings, marginal land surrounding airports or in power line corridors may support bees, even with small habitat patches. However, temporal surveys of wild bees are lacking for many urban areas such as the Puget Sound region of western Washington State, USA. Here, we conducted wild bee surveys at three peri-urban sites in the Puget Sound over 7 years. Specifically, a standardized protocol was used to sample wild bee communities monthly from April to October at two sites associated with airports and one site in a power line corridor. In total, our surveys collected 25,441 specimens representing 118 confirmed species within 24 genera, with individual subsites having between 15 and 35 species in any year. The Halictidae represented the largest number of individuals collected, with 47% of specimens. By genus, was the most speciose ( = 21), with , , and also ubiquitous and diverse. Bee diversity was high across spring and summer, and our surveys resolved the presumptive overlap of parasites with their hosts. Our study shows that marginal lands requiring little management can support diverse wild bee communities in urban areas. Our work also provides a baseline for future evaluations of wild bee communities in the Puget Sound and broader Pacific Northwest.
城市生态系统中的野生蜜蜂群落常常受到栖息地破碎化和低花卉多样性的挑战。在这种情况下，机场周边或输电线走廊的边缘土地可能会为蜜蜂提供支持，即使栖息地斑块较小。然而，美国华盛顿州西部普吉特海湾地区等许多城市地区缺乏对野生蜜蜂的长期调查。在此，我们在普吉特海湾的三个城郊地点进行了为期7年的野生蜜蜂调查。具体而言，我们采用标准化方案，于4月至10月每月在两个与机场相关的地点和一个输电线走廊地点对野生蜜蜂群落进行采样。我们的调查总共收集了25441个标本，代表24个属中的118个已确认物种，任何一年中各个子地点的物种数在15至35种之间。隧蜂科的采集个体数量最多，占标本的47%。按属来看，Lasioglossum种类最多（21种），Andrena、Bombus和Perdita也很常见且多样。春季和夏季的蜜蜂多样性都很高，我们的调查确定了寄生虫与其宿主之间可能存在的重叠情况。我们的研究表明，几乎无需管理的边缘土地能够支持城市地区多样化的野生蜜蜂群落。我们的工作还为未来对普吉特海湾及更广阔的太平洋西北地区野生蜜蜂群落的评估提供了一个基线。
