Data from: Beneath the buzz: Quantifying nest locations and densities of ground-nesting wild bees (Hymenoptera: Anthophila)

Data for the publication Hellerich et al. (2025) in <i>Methods in Ecology and Evolution</i>: Beneath the buzz: Quantifying nest locations and densities of ground-nesting wild bees (Hymenoptera: Anthophila). The dataset contains all bee specimens collected during the 2023 field survey using emergence traps. Data fields include information about collected species, time and site of collection, levels of wear and phenological remarks used to classify nesting activity and nests estimated this way.Nesting activity was classified based on the categories suggested by Portman et al. (2022) for the level of wear of wings and mandibles: 1 = Unworn (no nicks on the wings / no scratches on the mandibles and their shiny surface reaching the very tip); 2 = Slightly worn (one or two small nicks on the wings / shiny surface of the mandibles worn at the very tip, combined with small scratches); 3= Moderatly or extremly worn (multiple nicks or tears on the wings / noticeably worn down mandibles).

发表于《Methods in Ecology and Evolution》（生态学与进化方法）的Hellerich等人（2025）论文配套数据集：《嗡鸣之下：量化野生地面筑巢蜂的巢穴位置与种群密度（膜翅目（Hymenoptera）：蜂亚目（Anthophila））》。本数据集收录了2023年野外调查期间使用羽化诱捕器（emergence trap）采集的所有蜂类标本。数据字段涵盖采集物种、采集时间与采集地点、磨损程度分级信息，以及用于判定筑巢活动并据此估算巢穴数量的物候备注内容。筑巢活动的分级依据Portman等人（2022）提出的翅与上颚（mandibles）磨损程度分级标准，具体如下：1级：无磨损（翅部无缺刻 / 上颚及其光亮表面未出现延伸至尖端的划痕）；2级：轻度磨损（翅部存在1至2处细小缺刻 / 上颚光亮表面尖端出现磨损，伴随细小划痕）；3级：中度或极度磨损（翅部存在多处缺刻或撕裂 / 上颚出现明显磨损）。
