Nectar accessibility and flower-specific hoverfly longevity, choice, visitation and abundance

The Excel file contains 5 data sets, one for each test described in the related paper: 1. Flower size of selected plants species. 2. Hoverfly survival: survival time of male and female Episyrphus balteatus in relation to the flower species present in cage. 3. Flower choice: time allocation of male and female Episyrphus balteatus to one of four flower species present in cage, translated into selection events. 4. Flower visitation: composition of flower visiting insects per plant species in field margin strips. 5. Hoverfly abundance: number of zoophagous hoverflies (and other flower-visiting insects) in relation to flower abundance and composition of field margin strips.
The first sheet provides a more detailed description of the 5 data sets.

本Excel文件包含5组数据集，分别对应相关论文中记载的5项试验：
1. 受试植物物种的花部尺寸
2. 食蚜蝇存活特性：条斑食蚜蝇（Episyrphus balteatus）雌雄成虫的存活时长与饲养笼内供试花卉物种的相关性
3. 花卉选择偏好：条斑食蚜蝇雌雄成虫对饲养笼内4种供试花卉的时间分配情况，该数据已转化为选择事件统计量
4. 访花昆虫组成：农田边际带内各植物物种对应的访花昆虫群落组成
5. 食蚜蝇种群丰度：肉食性食蚜蝇（及其他访花昆虫）的种群数量与农田边际带内花卉丰度及群落组成的相关性

该文件的首个工作表对上述5组数据集进行了详细说明。
