Urbanization poses threats and opportunities for the biodiversity of wild bees. At the same time, cities can harbor diverse wild bee assemblages, partly due to the unique plant assemblages that provide resources. While bee dietary preferences have been investigated in various studies, bee dietary studies have been conducted mostly in nonurban ecosystems and data based on plant visitation observations or palynological techniques. This data set describes the larval food preferences of four wild bee species (i.e., Chelostoma florisomne, Hylaeus communis, Osmia bicornis, and O. cornuta) common in urban areas in five different European cities (i.e., Antwerp, Belgium; Paris, France; Poznan, Poland; Tartu, Estonia; and Zurich, Switzerland). In addition, the data set describes the larval food preferences of individuals from three wild bee genera (i.e., Chelostoma sp., Hylaeus sp., and Osmia sp.) that could not be identified to the species level. These data were obtained from a Europe-level study aimed at understanding the effects of urbanization on biodiversity across different cities and cityscapes and a Swiss project aimed at understanding the effects of urban ecosystems in wild bee feeding behavior. Wild bees were sampled using standardized trap nests at 80 sites (32 in Zurich and 12 in each of the remaining cities), selected following a double gradient of available habitat at local and landscape scales. Larval pollen was obtained from the bee nests and identified using DNA metabarcoding. The data provide the plant composition at the species or genus level preferred by each bee. These unique data can be used for a wide array of research questions, including urban ecology (e.g., diversity of food sources along urban gradients), bee ecology (characterization of bee feeding preferences), or comparative studies on the urban evolution of behavioral traits between urban and nonurban sites. In addition, the data can be used to inform urban planning and conservation strategies, particularly concerning flower resources (e.g., importance of exotic species and, thus, management activities). This data set can be freely used for noncommercial purposes, and this data paper should be cited if the data is used; we request that collaboration with the data set contact person to be considered if this data set represents an important part of the data analyzed in a study.
城市化对野生蜜蜂的生物多样性既构成威胁，又带来机遇。与此同时，城市可以容纳多种多样的野生蜜蜂群落，部分原因是城市拥有提供资源的独特植物组合。虽然已经对蜜蜂的饮食偏好进行了各种研究，但这些研究主要是在非城市生态系统中进行的，并且数据是基于植物访问观察或孢粉学技术。本数据集描述了在五个不同欧洲城市（比利时安特卫普、法国巴黎、波兰波兹南、爱沙尼亚塔尔图和瑞士苏黎世）的城市地区常见的四种野生蜜蜂物种（Chelostoma florisomne、Hylaeus communis、Osmia bicornis 和 O. cornuta）的幼虫食物偏好。此外，该数据集还描述了无法确定种属水平的三种野生蜜蜂属（Chelostoma sp.、Hylaeus sp. 和 Osmia sp.）个体的幼虫食物偏好。这些数据来自一项旨在了解不同城市和城市景观中城市化对生物多样性影响的欧洲层面研究，以及一项旨在了解城市生态系统对野生蜜蜂取食行为影响的瑞士项目。使用标准化的陷阱巢在 80 个地点（苏黎世 32 个，其余每个城市 12 个）采集野生蜜蜂样本，这些地点是在本地和景观尺度上可用栖息地的双梯度选择的。从蜜蜂巢穴中获取幼虫花粉，并使用 DNA metabarcoding 进行鉴定。该数据提供了每种蜜蜂偏好的植物组成（种或属水平）。这些独特的数据可用于广泛的研究问题，包括城市生态学（例如，城市梯度上食物源的多样性）、蜜蜂生态学（蜜蜂取食偏好的特征）或城市和非城市地点之间行为特征的城市进化比较研究。此外，这些数据还可用于为城市规划和保护策略提供信息，特别是在花卉资源方面（例如，外来物种的重要性以及因此的管理活动）。本数据集可免费用于非商业目的，如果使用了这些数据，则应引用本文；我们要求在研究中分析的数据集是重要部分的情况下，与数据集联系人合作。
